The user performs necessary +actions via a Python script called `setup.py'. For simple programs, +this is straight-forward. However, for more complex software packages, +especially for those which also include code in other languages such as +C or Fortran, the limitations of the `distutils' method quickly become +apparent. + + The configuration and installation of GNU software and many other +programs, on the other hand, is done according to the use of standard +`configure' scripts and Make recipes. This method has the advantage of +being language-agnostic, very flexible, time-proven. pyconfigure +consists of all the files necessary to use the standard GNU build +process to configure and install Python packages. + + Without modification, pyconfigure provides a wrapper around +`setup.py', which allows the user to use the familiar GNU installation +commands to install a Python package. With the powerful Autoconf macros +that it provides, a Python developer can greatly extend or even replace +altogether the capabilities of `setup.py'. Plus, since this method is +language-agnostic, all the power of Autoconf for compiled languages is +gained for free. + +* Menu: + +* Configuring Python packages:: + + +File: pyconfigure.info, Node: Configuring Python packages, Prev: Introduction, Up: Introduction + +1.1 Configuring Python packages +=============================== + +Configuring and installing Python packages which use pyconfigure +follows the familiar steps of all standard GNU software: + + $ ./configure + $ make + $ make install + + In fact, since most programs do not have anything to build, the +second step could usually be skipped. + + As usual, the user may pass arguments to `configure' in order to +specify how she wants the software to be installed. By default, +`configure' takes the following useful arguments: + +Argument Description +-------------------------------------------------------------------------- +`--prefix' Set the root directory in which to install files + (default=/usr/local) +`--with-virtualenv'Install to a virtualenv at `$prefix' +`PYTHON' Path to the Python interpreter to use +`PYTHONPATH' The PYTHONPATH to use during the installation + + However, as the developer is expected to customize these files, the +final `configure' script may take many more arguments.

In particular, you will want to customize +`configure.ac' and `Makefile.in'. `configure.ac' contains a series of +macros which are used by Autoconf to build a portable `configure' shell +script. This script either guesses important system settings or is +provided them by the user. When the user invokes `configure', it uses +`Makefile.in' as a template to create the Make recipe `Makefile'. + + Several Autoconf macros are provided in the pyconfigure file +`src/m4/python.m4' to allow the developer to write robust tests *Note +Autoconf macros::. Note that when you distribute your software, you +must include this directory and file with your distribution. + + Once you modify your `configure.ac' to your liking, you must +regenerate your `configure' script with autoreconf: + + $ autoreconf -fvi + + A full explanation of the use of Autoconf macros is beyond the scope +of this document, however it is worth presenting some examples. + +* Menu: + +* Required macros:: +* Verifying the Python version:: +* Checking for a module or function:: +* Writing test programs:: +* Using Sphinxbuild to build documentation:: + + +File: pyconfigure.info, Node: Required macros, Next: Verifying the Python version, Prev: Using pyconfigure, Up: Using pyconfigure + +2.1 Required macros +=================== + +Several macros are required in `configure.ac' to use pyconfigure. These +are: + + m4_include([m4/python.m4]) + + This macro imports all of the Python Autoconf macros. If you choose +to write your own macros for other purposes, you would also include them +in this manner. + + AC_INIT(project_name, project_version) + + This initializes Autoconf and also substitutes your project name and +version in any output that it generates. + + AC_CONFIG_MACRO_DIR([m4]) + + Now that Autoconf is initialized, we inform it of the location of our +macros. + + AC_PROG_PYTHON + + This is the key macro. It finds the highest-version Python +interpreter available on the system and saves its path in the `PYTHON' +variable. + + PC_PYTHON_SITE_PACKAGE_DIR + PC_PYTHON_EXEC_PACKAGE_DIR + + These two macros figure out where Python expects packages to be +installed (i.e. `/usr/lib/python2.7/site-packages/') and saves them in +the variables `pkgpythondir' and `pkgpyexecdir', respectively, for use +in `Makefile.in' + + +File: pyconfigure.info, Node: Verifying the Python version, Next: Checking for a module or function, Prev: Required macros, Up: Using pyconfigure + +2.2 Verifying the Python version +================================ + +As described in the previous section, `AC_PROG_PYTHON' finds the Python +interpreter with the highest version installed on the system. Often, +you will want to be sure that the user has some minimum version +installed. There is a macro available to simplify this, +`PC_PYTHON_VERIFY_VERSION'. + + m4_define(python_min_ver, 2.6.1) + PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , + [AC_MSG_ERROR(Python interpreter too old)]) + + In this example, we set the minimum version to 2.6.1 through the use +of an M4 macro. We then check if the interpreter stored in the `PYTHON' +variable (either set by the user or found by `AC_PROG_PYTHON') is at +least of that version. If it is not, the resulting `configure' script +will exit with an appropriate error message. + + Unfortunately, the divide between Python 2 and Python 3 and many +programs are only compatible with Python 2. Since `AC_PROG_PYTHON' will +find the latest Python interpreter, if the user has any Python version +3.x installed, `configure' must be able to instead find the most latest +2.x version installed. This is slightly less straight-forward, but one +possible implementation is as follows: + + PC_PYTHON_VERIFY_VERSION([$PYTHON], 3.0, + py3k=true, + py3k=false) + # If a Python 3 interpreter was found, look specifically for a Python 2 one + if test "$py3k" = "true" ; then + m4_define_default([_PYTHON2_BINS], [python2 python2.7 python2.6]) + AC_PATH_PROGS(PYTHON, [_PYTHON2_BINS]) + else + # otherwise check that the Python 2 version is sufficient + PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , + [AC_MSG_ERROR(Python interpreter too old)]) + fi + if test -z "$PYTHON"; then + AC_MSG_ERROR(No Python 2 interpreter found) + fi + + We first check to see if Python is version 3.0 or greater. If it is, +we create a list of compatible Python interpreters and manually check +for them using standard Autoconf macros. Finally, we check if the +interpreter that we found this time is of sufficient version, otherwise +`configure' will halt with an error. Likewise, if no appropriate +interpreter was found, an error message will be printed and `configure' +will stop. + + +File: pyconfigure.info, Node: Checking for a module or function, Next: Writing test programs, Prev: Verifying the Python version, Up: Using pyconfigure + +2.3 Checking for a module or function +===================================== + +It's reasonable to assume that many Python packages will have +dependencies on other, external modules. With the provided pyconfigure +macros, this is simple. All you have to do is use the +`PC_PYTHON_CHECK_MODULE' macro as follows: + + PC_PYTHON_CHECK_MODULE([foo]) + + If the module is a hard requirement, you may provide actions to do if +it is not present: + + PC_PYTHON_CHECK_MODULE([foo], , AC_MSG_ERROR([Module foo is not installed])) + + If you need more fine-grained control, you can also test for a +specific function: + + PC_PYTHON_CHECK_FUNC([foo], [bar], [arg1, arg2]) + + Remember that you may omit arguments to Autoconf macros: in the above +example, the final two arguments, which correspond to the action to +take if the test is successful and if it fails simply are not present +in the argument list. Similarly, if you do not need to pass arguments +to the test function, you can entirely omit the third argument to the +macro: + + PC_PYTHON_CHECK_FUNC([foo], [bar]) + + +File: pyconfigure.info, Node: Writing test programs, Next: Using Sphinxbuild to build documentation, Prev: Checking for a module or function, Up: Using pyconfigure + +2.4 Writing test programs +========================= + +One great benefit of Autoconf is the ability to embed test programs +inside `configure'. The pyconfigure macros allow for this by defining +Python as a language within Autoconf. You then would proceed to write +test programs as you would in any other language that Autoconf supports +like C. + + AC_LANG_PUSH(Python)[] + AC_RUN_IFELSE([AC_LANG_PROGRAM([dnl + # some code here + import foo + ], [dnl + # some more code here + foo.bar() + ])], [ACTION-IF-SUCCESSFUL], [ACTION-IF-FAILED]) + AC_LANG_POP(Python)[] + + The first argument to `AC_LANG_PROGRAM' is the so-called "prolog", +and typically will contain your `import' statements or function +definitions. The second argument contains the main body of the program, +which will be in the scope of an `if __name__=="__main__":' block. So, +you must be sure to indent the code appropriately. + + +File: pyconfigure.info, Node: Using Sphinxbuild to build documentation, Prev: Writing test programs, Up: Using pyconfigure + +2.5 Using Sphinxbuild to build documentation +============================================ + +Using pyconfigure and Autoconf to test for other tools is quite easy. +For example, many Python packages use Sphinxbuild to build their +documentation.

(Thus, if the Document + is in part a textbook of mathematics, a Secondary Section may not + explain any mathematics.) The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in + the notice that says that the Document is released under this + License. If a section does not fit the above definition of + Secondary then it is not allowed to be designated as Invariant. + The Document may contain zero Invariant Sections. If the Document + does not identify any Invariant Sections then there are none. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. A + Front-Cover Text may be at most 5 words, and a Back-Cover Text may + be at most 25 words. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images + composed of pixels) generic paint programs or (for drawings) some + widely available drawing editor, and that is suitable for input to + text formatters or for automatic translation to a variety of + formats suitable for input to text formatters. A copy made in an + otherwise Transparent file format whose markup, or absence of + markup, has been arranged to thwart or discourage subsequent + modification by readers is not Transparent. An image format is + not Transparent if used for any substantial amount of text. A + copy that is not "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and + standard-conforming simple HTML, PostScript or PDF designed for + human modification. Examples of transparent image formats include + PNG, XCF and JPG. Opaque formats include proprietary formats that + can be read and edited only by proprietary word processors, SGML or + XML for which the DTD and/or processing tools are not generally + available, and the machine-generated HTML, PostScript or PDF + produced by some word processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + The "publisher" means any person or entity that distributes copies + of the Document to the public. + + A section "Entitled XYZ" means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + "Acknowledgements", "Dedications", "Endorsements", or "History".) + To "Preserve the Title" of such a section when you modify the + Document means that it remains a section "Entitled XYZ" according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow + the conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the + title equally prominent and visible. You may add other material + on the covers in addition. Copying with changes limited to the + covers, as long as they preserve the title of the Document and + satisfy these conditions, can be treated as verbatim copying in + other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a + machine-readable Transparent copy along with each Opaque copy, or + state in or with each Opaque copy a computer-network location from + which the general network-using public has access to download + using public-standard network protocols a complete Transparent + copy of the Document, free of added material. If you use the + latter option, you must take reasonably prudent steps, when you + begin distribution of Opaque copies in quantity, to ensure that + this Transparent copy will remain thus accessible at the stated + location until at least one year after the last time you + distribute an Opaque copy (directly or through your agents or + retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of + copies, to give them a chance to provide you with an updated + version of the Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with + the Modified Version filling the role of the Document, thus + licensing distribution and modification of the Modified Version to + whoever possesses a copy of it. In addition, you must do these + things in the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of + previous versions (which should, if there were any, be listed + in the History section of the Document). You may use the + same title as a previous version if the original publisher of + that version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled "History", Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on + the Title Page. If there is no section Entitled "History" in + the Document, create one stating the title, year, authors, + and publisher of the Document as given on its Title Page, + then add an item describing the Modified Version as stated in + the previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in + the "History" section. You may omit a network location for a + work that was published at least four years before the + Document itself, or if the original publisher of the version + it refers to gives permission. + + K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the + section all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section + titles. + + M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option + designate some or all of these sections as invariant. To do this, + add their titles to the list of Invariant Sections in the Modified + Version's license notice. These titles must be distinct from any + other section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end + of the list of Cover Texts in the Modified Version. Only one + passage of Front-Cover Text and one of Back-Cover Text may be + added by (or through arrangements made by) any one entity. If the + Document already includes a cover text for the same cover, + previously added by you or by arrangement made by the same entity + you are acting on behalf of, you may not add another; but you may + replace the old one, on explicit permission from the previous + publisher that added the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination + all of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the + documents in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow + this License in all other respects regarding verbatim copying of + that document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of + a storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense, or distribute it is void, + and will automatically terminate your rights under this License. + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly + and finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from + you under this License. If your rights have been terminated and + not permanently reinstated, receipt of a copy of some or all of + the same material does not give you any rights to use it. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + `http://www.gnu.org/copyleft/'. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If + the Document does not specify a version number of this License, + you may choose any version ever published (not as a draft) by the + Free Software Foundation. If the Document specifies that a proxy + can decide which future versions of this License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Document. + + 11. RELICENSING + + "Massive Multiauthor Collaboration Site" (or "MMC Site") means any + World Wide Web server that publishes copyrightable works and also + provides prominent facilities for anybody to edit those works. A + public wiki that anybody can edit is an example of such a server. + A "Massive Multiauthor Collaboration" (or "MMC") contained in the + site means any set of copyrightable works thus published on the MMC + site. + + "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 + license published by Creative Commons Corporation, a not-for-profit + corporation with a principal place of business in San Francisco, + California, as well as future copyleft versions of that license + published by that same organization. + + "Incorporate" means to publish or republish a Document, in whole or + in part, as part of another Document. + + An MMC is "eligible for relicensing" if it is licensed under this + License, and if all works that were first published under this + License somewhere other than this MMC, and subsequently + incorporated in whole or in part into the MMC, (1) had no cover + texts or invariant sections, and (2) were thus incorporated prior + to November 1, 2008. + + The operator of an MMC Site may republish an MMC contained in the + site under CC-BY-SA on the same site at any time before August 1, + 2009, provided the MMC is eligible for relicensing. + + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.

The user performs +necessary actions via a Python script called @file{setup.py}. For +simple programs, this is straight-forward. However, for more complex +software packages, especially for those which also include code in +other languages such as C or Fortran, the limitations of the +@code{distutils} method quickly become apparent. + +The configuration and installation of GNU software and many other +programs, on the other hand, is done according to the use of standard +@file{configure} scripts and Make recipes. This method has the +advantage of being language-agnostic, very flexible, +time-proven. pyconfigure consists of all the files +necessary to use the standard GNU build process to configure and +install Python packages. + +Without modification, pyconfigure provides a wrapper +around @file{setup.py}, which allows the user to use the familiar GNU +installation commands to install a Python package. With the powerful +Autoconf macros that it provides, a Python developer can greatly +extend or even replace altogether the capabilities of +@file{setup.py}. Plus, since this method is language-agnostic, all the +power of Autoconf for compiled languages is gained for free. + +@menu +* Configuring Python packages:: +@end menu + +@node Configuring Python packages, , Introduction, Introduction +@section Configuring Python packages + +Configuring and installing Python packages which use +pyconfigure follows the familiar steps of all standard GNU +software: + +@example +$ ./configure +$ make +$ make install +@end example + +In fact, since most programs do not have anything to build, the second +step could usually be skipped. + +As usual, the user may pass arguments to @file{configure} in order to +specify how she wants the software to be installed. By default, +@file{configure} takes the following useful arguments: + +@multitable @columnfractions .25 .75 +@headitem +Argument +@tab +Description + +@item +@code{--prefix} +@tab +Set the root directory in which to install files (default=/usr/local) + +@item +@code{--with-virtualenv} +@tab +Install to a virtualenv at @code{$prefix} + +@item +@code{PYTHON} +@tab +Path to the Python interpreter to use + +@item +@code{PYTHONPATH} +@tab +The PYTHONPATH to use during the installation + +@end multitable + +However, as the developer is expected to customize these files, the +final @file{configure} script may take many more arguments. The +developer is expected to provide proper documentation in this case. + +@node Using pyconfigure, Appendix, Introduction, Top +@chapter Using pyconfigure + +While it is possible to simply copy the pyconfigure files from +the @file{src} directory into your project's source directory and use +them unmodified, it is recommended that you customize them to more +appropriately fit your needs. In particular, you will want to +customize @file{configure.ac} and +@file{Makefile.in}. @file{configure.ac} contains a series of macros +which are used by Autoconf to build a portable @file{configure} shell +script. This script either guesses important system settings or is +provided them by the user. When the user invokes @file{configure}, it +uses @file{Makefile.in} as a template to create the Make recipe +@file{Makefile}. + +Several Autoconf macros are provided in the pyconfigure file +@file{src/m4/python.m4} to allow the developer to write robust tests +@xref{Autoconf macros}. Note that when you distribute your software, +you must include this directory and file with your distribution. + +Once you modify your @file{configure.ac} to your liking, you must +regenerate your @file{configure} script with autoreconf: + +@example +$ autoreconf -fvi +@end example + +A full explanation of the use of Autoconf macros is beyond the scope +of this document, however it is worth presenting some examples. + +@menu +* Required macros:: +* Verifying the Python version:: +* Checking for a module or function:: +* Writing test programs:: +* Using Sphinxbuild to build documentation:: +@end menu + +@node Required macros, Verifying the Python version, Using pyconfigure, Using pyconfigure +@section Required macros + +Several macros are required in @file{configure.ac} to use +pyconfigure. These are: + +@example +m4_include([m4/python.m4]) +@end example + +This macro imports all of the Python Autoconf macros. If you choose to +write your own macros for other purposes, you would also include them +in this manner. + +@example +AC_INIT(project_name, project_version) +@end example + +This initializes Autoconf and also substitutes your project name and +version in any output that it generates. + +@example +AC_CONFIG_MACRO_DIR([m4]) +@end example + +Now that Autoconf is initialized, we inform it of the location of our +macros. + +@example +AC_PROG_PYTHON +@end example + +This is the key macro. It finds the highest-version Python interpreter +available on the system and saves its path in the @code{PYTHON} +variable. + +@example +PC_PYTHON_SITE_PACKAGE_DIR +PC_PYTHON_EXEC_PACKAGE_DIR +@end example + +These two macros figure out where Python expects packages to be +installed (i.e. @file{/usr/lib/python2.7/site-packages/}) and saves +them in the variables @code{pkgpythondir} and @code{pkgpyexecdir}, +respectively, for use in @file{Makefile.in} + +@node Verifying the Python version, Checking for a module or function, Required macros, Using pyconfigure +@section Verifying the Python version + +As described in the previous section, @code{AC_PROG_PYTHON} finds the +Python interpreter with the highest version installed on the +system. Often, you will want to be sure that the user has some minimum +version installed. There is a macro available to simplify this, +@code{PC_PYTHON_VERIFY_VERSION}. + +@example +m4_define(python_min_ver, 2.6.1) +PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , + [AC_MSG_ERROR(Python interpreter too old)]) +@end example + +In this example, we set the minimum version to 2.6.1 through the use +of an M4 macro. We then check if the interpreter stored in the +@code{PYTHON} variable (either set by the user or found by +@code{AC_PROG_PYTHON}) is at least of that version. If it is not, the +resulting @file{configure} script will exit with an appropriate error +message. + +Unfortunately, the divide between Python 2 and Python 3 and many +programs are only compatible with Python 2. Since +@code{AC_PROG_PYTHON} will find the latest Python interpreter, if the +user has any Python version 3.x installed, @code{configure} must be +able to instead find the most latest 2.x version installed. This is +slightly less straight-forward, but one possible implementation is as +follows: + +@example +PC_PYTHON_VERIFY_VERSION([$PYTHON], 3.0, + py3k=true, + py3k=false) +# If a Python 3 interpreter was found, look specifically for a Python 2 one +if test "$py3k" = "true" ; then + m4_define_default([_PYTHON2_BINS], [python2 python2.7 python2.6]) + AC_PATH_PROGS(PYTHON, [_PYTHON2_BINS]) +else +# otherwise check that the Python 2 version is sufficient + PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , + [AC_MSG_ERROR(Python interpreter too old)]) +fi +if test -z "$PYTHON"; then + AC_MSG_ERROR(No Python 2 interpreter found) +fi +@end example + +We first check to see if Python is version 3.0 or greater. If it is, +we create a list of compatible Python interpreters and manually check +for them using standard Autoconf macros. Finally, we check if the +interpreter that we found this time is of sufficient version, +otherwise @file{configure} will halt with an error. Likewise, if no +appropriate interpreter was found, an error message will be printed +and @file{configure} will stop. + +@node Checking for a module or function, Writing test programs, Verifying the Python version, Using pyconfigure +@section Checking for a module or function + +It's reasonable to assume that many Python packages will have +dependencies on other, external modules. With the provided +pyconfigure macros, this is simple. All you have to do is use the +@code{PC_PYTHON_CHECK_MODULE} macro as follows: + +@example +PC_PYTHON_CHECK_MODULE([foo]) +@end example + +If the module is a hard requirement, you may provide actions to do if +it is not present: + +@example +PC_PYTHON_CHECK_MODULE([foo], , AC_MSG_ERROR([Module foo is not installed])) +@end example + +If you need more fine-grained control, you can also test for a +specific function: + +@example +PC_PYTHON_CHECK_FUNC([foo], [bar], [arg1, arg2]) +@end example + +Remember that you may omit arguments to Autoconf macros: in the above +example, the final two arguments, which correspond to the action to +take if the test is successful and if it fails simply are not present +in the argument list. Similarly, if you do not need to pass arguments +to the test function, you can entirely omit the third argument to the +macro: + +@example +PC_PYTHON_CHECK_FUNC([foo], [bar]) +@end example + +@node Writing test programs, Using Sphinxbuild to build documentation, Checking for a module or function, Using pyconfigure +@section Writing test programs + +One great benefit of Autoconf is the ability to embed test programs +inside @file{configure}. The pyconfigure macros allow for this by +defining Python as a language within Autoconf. You then would proceed +to write test programs as you would in any other language that +Autoconf supports like C. + +@example +AC_LANG_PUSH(Python)[] +AC_RUN_IFELSE([AC_LANG_PROGRAM([dnl +# some code here +import foo +], [dnl + # some more code here + foo.bar() +])], [ACTION-IF-SUCCESSFUL], [ACTION-IF-FAILED]) +AC_LANG_POP(Python)[] +@end example + +The first argument to @code{AC_LANG_PROGRAM} is the so-called +``prolog'', and typically will contain your @code{import} statements +or function definitions. The second argument contains the main body of +the program, which will be in the scope of an @code{if __name__=="__main__":} +block.

The user performs necessary -actions via a Python script called `setup.py'. For simple programs, -this is straight-forward. However, for more complex software packages, -especially for those which also include code in other languages such as -C or Fortran, the limitations of the `distutils' method quickly become -apparent. - - The configuration and installation of GNU software and many other -programs, on the other hand, is done according to the use of standard -`configure' scripts and Make recipes. This method has the advantage of -being language-agnostic, very flexible, time-proven. python-configure -consists of all the files necessary to use the standard GNU build -process to configure and install Python packages. - - Without modification, python-configure provides a wrapper around -`setup.py', which allows the user to use the familiar GNU installation -commands to install a Python package. With the powerful Autoconf macros -that it provides, a Python developer can greatly extend or even replace -altogether the capabilities of `setup.py'. Plus, since this method is -language-agnostic, all the power of Autoconf for compiled languages is -gained for free. - -* Menu: - -* Configuring Python packages:: - - -File: python-configure.info, Node: Configuring Python packages, Prev: Introduction, Up: Introduction - -1.1 Configuring Python packages -=============================== - -Configuring and installing Python packages which use python-configure -follows the familiar steps of all standard GNU software: - - $ ./configure - $ make - $ make install - - In fact, since most programs do not have anything to build, the -second step could usually be skipped. - - As usual, the user may pass arguments to `configure' in order to -specify how she wants the software to be installed. By default, -`configure' takes the following useful arguments: - -Argument Description --------------------------------------------------------------------------- -`--prefix' Set the root directory in which to install files - (default=/usr/local) -`--with-virtualenv'Install to a virtualenv at `$prefix' -`PYTHON' Path to the Python interpreter to use -`PYTHONPATH' The PYTHONPATH to use during the installation - - However, as the developer is expected to customize these files, the -final `configure' script may take many more arguments. The developer is -expected to provide proper documentation in this case. - - -File: python-configure.info, Node: Using python-configure, Next: Appendix, Prev: Introduction, Up: Top - -2 Using python-configure -************************ - -While it is possible to simply copy the python-configure files from the -`src' directory into your project's source directory and use them -unmodified, it is recommended that you customize them to more -appropriately fit your needs. In particular, you will want to customize -`configure.ac' and `Makefile.in'. `configure.ac' contains a series of -macros which are used by Autoconf to build a portable `configure' shell -script. This script either guesses important system settings or is -provided them by the user. When the user invokes `configure', it uses -`Makefile.in' as a template to create the Make recipe `Makefile'. - - Several Autoconf macros are provided in the python-configure file -`src/m4/python.m4' to allow the developer to write robust tests *Note -Autoconf macros::. Note that when you distribute your software, you -must include this directory and file with your distribution. - - Once you modify your `configure.ac' to your liking, you must -regenerate your `configure' script with autoreconf: - - $ autoreconf -fvi - - A full explanation of the use of Autoconf macros is beyond the scope -of this document, however it is worth presenting some examples. - -* Menu: - -* Required macros:: -* Verifying the Python version:: -* Checking for a module or function:: -* Writing test programs:: -* Using Sphinxbuild to build documentation:: - - -File: python-configure.info, Node: Required macros, Next: Verifying the Python version, Prev: Using python-configure, Up: Using python-configure - -2.1 Required macros -=================== - -Several macros are required in `configure.ac' to use python-configure. -These are: - - m4_include([m4/python.m4]) - - This macro imports all of the Python Autoconf macros. If you choose -to write your own macros for other purposes, you would also include them -in this manner. - - AC_INIT(project_name, project_version) - - This initializes Autoconf and also substitutes your project name and -version in any output that it generates. - - AC_CONFIG_MACRO_DIR([m4]) - - Now that Autoconf is initialized, we inform it of the location of our -macros. - - AC_PROG_PYTHON - - This is the key macro. It finds the highest-version Python -interpreter available on the system and saves its path in the `PYTHON' -variable. - - PC_PYTHON_SITE_PACKAGE_DIR - PC_PYTHON_EXEC_PACKAGE_DIR - - These two macros figure out where Python expects packages to be -installed (i.e. `/usr/lib/python2.7/site-packages/') and saves them in -the variables `pkgpythondir' and `pkgpyexecdir', respectively, for use -in `Makefile.in' - - -File: python-configure.info, Node: Verifying the Python version, Next: Checking for a module or function, Prev: Required macros, Up: Using python-configure - -2.2 Verifying the Python version -================================ - -As described in the previous section, `AC_PROG_PYTHON' finds the Python -interpreter with the highest version installed on the system. Often, -you will want to be sure that the user has some minimum version -installed. There is a macro available to simplify this, -`PC_PYTHON_VERIFY_VERSION'. - - m4_define(python_min_ver, 2.6.1) - PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , - [AC_MSG_ERROR(Python interpreter too old)]) - - In this example, we set the minimum version to 2.6.1 through the use -of an M4 macro. We then check if the interpreter stored in the `PYTHON' -variable (either set by the user or found by `AC_PROG_PYTHON') is at -least of that version. If it is not, the resulting `configure' script -will exit with an appropriate error message. - - Unfortunately, the divide between Python 2 and Python 3 and many -programs are only compatible with Python 2. Since `AC_PROG_PYTHON' will -find the latest Python interpreter, if the user has any Python version -3.x installed, `configure' must be able to instead find the most latest -2.x version installed. This is slightly less straight-forward, but one -possible implementation is as follows: - - PC_PYTHON_VERIFY_VERSION([$PYTHON], 3.0, - py3k=true, - py3k=false) - # If a Python 3 interpreter was found, look specifically for a Python 2 one - if test "$py3k" = "true" ; then - m4_define_default([_PYTHON2_BINS], [python2 python2.7 python2.6]) - AC_PATH_PROGS(PYTHON, [_PYTHON2_BINS]) - else - # otherwise check that the Python 2 version is sufficient - PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , - [AC_MSG_ERROR(Python interpreter too old)]) - fi - if test -z "$PYTHON"; then - AC_MSG_ERROR(No Python 2 interpreter found) - fi - - We first check to see if Python is version 3.0 or greater. If it is, -we create a list of compatible Python interpreters and manually check -for them using standard Autoconf macros. Finally, we check if the -interpreter that we found this time is of sufficient version, otherwise -`configure' will halt with an error. Likewise, if no appropriate -interpreter was found, an error message will be printed and `configure' -will stop. - - -File: python-configure.info, Node: Checking for a module or function, Next: Writing test programs, Prev: Verifying the Python version, Up: Using python-configure - -2.3 Checking for a module or function -===================================== - -It's reasonable to assume that many Python packages will have -dependencies on other, external modules. With the provided -python-configure macros, this is simple. All you have to do is use the -`PC_PYTHON_CHECK_MODULE' macro as follows: - - PC_PYTHON_CHECK_MODULE([foo]) - - If the module is a hard requirement, you may provide actions to do if -it is not present: - - PC_PYTHON_CHECK_MODULE([foo], , AC_MSG_ERROR([Module foo is not installed])) - - If you need more fine-grained control, you can also test for a -specific function: - - PC_PYTHON_CHECK_FUNC([foo], [bar], [arg1, arg2]) - - Remember that you may omit arguments to Autoconf macros: in the above -example, the final two arguments, which correspond to the action to -take if the test is successful and if it fails simply are not present -in the argument list. Similarly, if you do not need to pass arguments -to the test function, you can entirely omit the third argument to the -macro: - - PC_PYTHON_CHECK_FUNC([foo], [bar]) - - -File: python-configure.info, Node: Writing test programs, Next: Using Sphinxbuild to build documentation, Prev: Checking for a module or function, Up: Using python-configure - -2.4 Writing test programs -========================= - -One great benefit of Autoconf is the ability to embed test programs -inside `configure'. The python-configure macros allow for this by -defining Python as a language within Autoconf. You then would proceed -to write test programs as you would in any other language that Autoconf -supports like C. - - AC_LANG_PUSH(Python)[] - AC_RUN_IFELSE([AC_LANG_PROGRAM([dnl - # some code here - import foo - ], [dnl - # some more code here - foo.bar() - ])], [ACTION-IF-SUCCESSFUL], [ACTION-IF-FAILED]) - AC_LANG_POP(Python)[] - - The first argument to `AC_LANG_PROGRAM' is the so-called "prolog", -and typically will contain your `import' statements or function -definitions. The second argument contains the main body of the program, -which will be in the scope of an `if __name__=="__main__":' block. So, -you must be sure to indent the code appropriately. - - -File: python-configure.info, Node: Using Sphinxbuild to build documentation, Prev: Writing test programs, Up: Using python-configure - -2.5 Using Sphinxbuild to build documentation -============================================ - -Using python-configure and Autoconf to test for other tools is quite -easy.

Copying with changes limited to the - covers, as long as they preserve the title of the Document and - satisfy these conditions, can be treated as verbatim copying in - other respects. - - If the required texts for either cover are too voluminous to fit - legibly, you should put the first ones listed (as many as fit - reasonably) on the actual cover, and continue the rest onto - adjacent pages. - - If you publish or distribute Opaque copies of the Document - numbering more than 100, you must either include a - machine-readable Transparent copy along with each Opaque copy, or - state in or with each Opaque copy a computer-network location from - which the general network-using public has access to download - using public-standard network protocols a complete Transparent - copy of the Document, free of added material. If you use the - latter option, you must take reasonably prudent steps, when you - begin distribution of Opaque copies in quantity, to ensure that - this Transparent copy will remain thus accessible at the stated - location until at least one year after the last time you - distribute an Opaque copy (directly or through your agents or - retailers) of that edition to the public. - - It is requested, but not required, that you contact the authors of - the Document well before redistributing any large number of - copies, to give them a chance to provide you with an updated - version of the Document. - - 4. MODIFICATIONS - - You may copy and distribute a Modified Version of the Document - under the conditions of sections 2 and 3 above, provided that you - release the Modified Version under precisely this License, with - the Modified Version filling the role of the Document, thus - licensing distribution and modification of the Modified Version to - whoever possesses a copy of it. In addition, you must do these - things in the Modified Version: - - A. Use in the Title Page (and on the covers, if any) a title - distinct from that of the Document, and from those of - previous versions (which should, if there were any, be listed - in the History section of the Document). You may use the - same title as a previous version if the original publisher of - that version gives permission. - - B. List on the Title Page, as authors, one or more persons or - entities responsible for authorship of the modifications in - the Modified Version, together with at least five of the - principal authors of the Document (all of its principal - authors, if it has fewer than five), unless they release you - from this requirement. - - C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. - - D. Preserve all the copyright notices of the Document. - - E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. - - F. Include, immediately after the copyright notices, a license - notice giving the public permission to use the Modified - Version under the terms of this License, in the form shown in - the Addendum below. - - G. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's - license notice. - - H. Include an unaltered copy of this License. - - I. Preserve the section Entitled "History", Preserve its Title, - and add to it an item stating at least the title, year, new - authors, and publisher of the Modified Version as given on - the Title Page. If there is no section Entitled "History" in - the Document, create one stating the title, year, authors, - and publisher of the Document as given on its Title Page, - then add an item describing the Modified Version as stated in - the previous sentence. - - J. Preserve the network location, if any, given in the Document - for public access to a Transparent copy of the Document, and - likewise the network locations given in the Document for - previous versions it was based on. These may be placed in - the "History" section. You may omit a network location for a - work that was published at least four years before the - Document itself, or if the original publisher of the version - it refers to gives permission. - - K. For any section Entitled "Acknowledgements" or "Dedications", - Preserve the Title of the section, and preserve in the - section all the substance and tone of each of the contributor - acknowledgements and/or dedications given therein. - - L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section - titles. - - M. Delete any section Entitled "Endorsements". Such a section - may not be included in the Modified Version. - - N.

TRANSLATION - - Translation is considered a kind of modification, so you may - distribute translations of the Document under the terms of section - 4. Replacing Invariant Sections with translations requires special - permission from their copyright holders, but you may include - translations of some or all Invariant Sections in addition to the - original versions of these Invariant Sections. You may include a - translation of this License, and all the license notices in the - Document, and any Warranty Disclaimers, provided that you also - include the original English version of this License and the - original versions of those notices and disclaimers. In case of a - disagreement between the translation and the original version of - this License or a notice or disclaimer, the original version will - prevail. - - If a section in the Document is Entitled "Acknowledgements", - "Dedications", or "History", the requirement (section 4) to - Preserve its Title (section 1) will typically require changing the - actual title. - - 9.

The user performs -necessary actions via a Python script called @file{setup.py}. For -simple programs, this is straight-forward. However, for more complex -software packages, especially for those which also include code in -other languages such as C or Fortran, the limitations of the -@code{distutils} method quickly become apparent. - -The configuration and installation of GNU software and many other -programs, on the other hand, is done according to the use of standard -@file{configure} scripts and Make recipes. This method has the -advantage of being language-agnostic, very flexible, -time-proven. python-configure consists of all the files -necessary to use the standard GNU build process to configure and -install Python packages. - -Without modification, python-configure provides a wrapper -around @file{setup.py}, which allows the user to use the familiar GNU -installation commands to install a Python package. With the powerful -Autoconf macros that it provides, a Python developer can greatly -extend or even replace altogether the capabilities of -@file{setup.py}. Plus, since this method is language-agnostic, all the -power of Autoconf for compiled languages is gained for free. - -@menu -* Configuring Python packages:: -@end menu - -@node Configuring Python packages, , Introduction, Introduction -@section Configuring Python packages - -Configuring and installing Python packages which use -python-configure follows the familiar steps of all standard GNU -software: - -@example -$ ./configure -$ make -$ make install -@end example - -In fact, since most programs do not have anything to build, the second -step could usually be skipped. - -As usual, the user may pass arguments to @file{configure} in order to -specify how she wants the software to be installed. By default, -@file{configure} takes the following useful arguments: - -@multitable @columnfractions .25 .75 -@headitem -Argument -@tab -Description - -@item -@code{--prefix} -@tab -Set the root directory in which to install files (default=/usr/local) - -@item -@code{--with-virtualenv} -@tab -Install to a virtualenv at @code{$prefix} - -@item -@code{PYTHON} -@tab -Path to the Python interpreter to use - -@item -@code{PYTHONPATH} -@tab -The PYTHONPATH to use during the installation - -@end multitable - -However, as the developer is expected to customize these files, the -final @file{configure} script may take many more arguments. The -developer is expected to provide proper documentation in this case. - -@node Using python-configure, Appendix, Introduction, Top -@chapter Using python-configure - -While it is possible to simply copy the python-configure files from -the @file{src} directory into your project's source directory and use -them unmodified, it is recommended that you customize them to more -appropriately fit your needs. In particular, you will want to -customize @file{configure.ac} and -@file{Makefile.in}. @file{configure.ac} contains a series of macros -which are used by Autoconf to build a portable @file{configure} shell -script. This script either guesses important system settings or is -provided them by the user. When the user invokes @file{configure}, it -uses @file{Makefile.in} as a template to create the Make recipe -@file{Makefile}. - -Several Autoconf macros are provided in the python-configure file -@file{src/m4/python.m4} to allow the developer to write robust tests -@xref{Autoconf macros}. Note that when you distribute your software, -you must include this directory and file with your distribution. - -Once you modify your @file{configure.ac} to your liking, you must -regenerate your @file{configure} script with autoreconf: - -@example -$ autoreconf -fvi -@end example - -A full explanation of the use of Autoconf macros is beyond the scope -of this document, however it is worth presenting some examples. - -@menu -* Required macros:: -* Verifying the Python version:: -* Checking for a module or function:: -* Writing test programs:: -* Using Sphinxbuild to build documentation:: -@end menu - -@node Required macros, Verifying the Python version, Using python-configure, Using python-configure -@section Required macros - -Several macros are required in @file{configure.ac} to use -python-configure. These are: - -@example -m4_include([m4/python.m4]) -@end example - -This macro imports all of the Python Autoconf macros. If you choose to -write your own macros for other purposes, you would also include them -in this manner. - -@example -AC_INIT(project_name, project_version) -@end example - -This initializes Autoconf and also substitutes your project name and -version in any output that it generates. - -@example -AC_CONFIG_MACRO_DIR([m4]) -@end example - -Now that Autoconf is initialized, we inform it of the location of our -macros. - -@example -AC_PROG_PYTHON -@end example - -This is the key macro. It finds the highest-version Python interpreter -available on the system and saves its path in the @code{PYTHON} -variable. - -@example -PC_PYTHON_SITE_PACKAGE_DIR -PC_PYTHON_EXEC_PACKAGE_DIR -@end example - -These two macros figure out where Python expects packages to be -installed (i.e. @file{/usr/lib/python2.7/site-packages/}) and saves -them in the variables @code{pkgpythondir} and @code{pkgpyexecdir}, -respectively, for use in @file{Makefile.in} - -@node Verifying the Python version, Checking for a module or function, Required macros, Using python-configure -@section Verifying the Python version - -As described in the previous section, @code{AC_PROG_PYTHON} finds the -Python interpreter with the highest version installed on the -system. Often, you will want to be sure that the user has some minimum -version installed. There is a macro available to simplify this, -@code{PC_PYTHON_VERIFY_VERSION}. - -@example -m4_define(python_min_ver, 2.6.1) -PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , - [AC_MSG_ERROR(Python interpreter too old)]) -@end example - -In this example, we set the minimum version to 2.6.1 through the use -of an M4 macro. We then check if the interpreter stored in the -@code{PYTHON} variable (either set by the user or found by -@code{AC_PROG_PYTHON}) is at least of that version. If it is not, the -resulting @file{configure} script will exit with an appropriate error -message. - -Unfortunately, the divide between Python 2 and Python 3 and many -programs are only compatible with Python 2. Since -@code{AC_PROG_PYTHON} will find the latest Python interpreter, if the -user has any Python version 3.x installed, @code{configure} must be -able to instead find the most latest 2.x version installed. This is -slightly less straight-forward, but one possible implementation is as -follows: - -@example -PC_PYTHON_VERIFY_VERSION([$PYTHON], 3.0, - py3k=true, - py3k=false) -# If a Python 3 interpreter was found, look specifically for a Python 2 one -if test "$py3k" = "true" ; then - m4_define_default([_PYTHON2_BINS], [python2 python2.7 python2.6]) - AC_PATH_PROGS(PYTHON, [_PYTHON2_BINS]) -else -# otherwise check that the Python 2 version is sufficient - PC_PYTHON_VERIFY_VERSION([$PYTHON], python_min_ver, , - [AC_MSG_ERROR(Python interpreter too old)]) -fi -if test -z "$PYTHON"; then - AC_MSG_ERROR(No Python 2 interpreter found) -fi -@end example - -We first check to see if Python is version 3.0 or greater. If it is, -we create a list of compatible Python interpreters and manually check -for them using standard Autoconf macros. Finally, we check if the -interpreter that we found this time is of sufficient version, -otherwise @file{configure} will halt with an error. Likewise, if no -appropriate interpreter was found, an error message will be printed -and @file{configure} will stop. - -@node Checking for a module or function, Writing test programs, Verifying the Python version, Using python-configure -@section Checking for a module or function - -It's reasonable to assume that many Python packages will have -dependencies on other, external modules. With the provided -python-configure macros, this is simple. All you have to do is use the -@code{PC_PYTHON_CHECK_MODULE} macro as follows: - -@example -PC_PYTHON_CHECK_MODULE([foo]) -@end example - -If the module is a hard requirement, you may provide actions to do if -it is not present: - -@example -PC_PYTHON_CHECK_MODULE([foo], , AC_MSG_ERROR([Module foo is not installed])) -@end example - -If you need more fine-grained control, you can also test for a -specific function: - -@example -PC_PYTHON_CHECK_FUNC([foo], [bar], [arg1, arg2]) -@end example - -Remember that you may omit arguments to Autoconf macros: in the above -example, the final two arguments, which correspond to the action to -take if the test is successful and if it fails simply are not present -in the argument list. Similarly, if you do not need to pass arguments -to the test function, you can entirely omit the third argument to the -macro: - -@example -PC_PYTHON_CHECK_FUNC([foo], [bar]) -@end example - -@node Writing test programs, Using Sphinxbuild to build documentation, Checking for a module or function, Using python-configure -@section Writing test programs - -One great benefit of Autoconf is the ability to embed test programs -inside @file{configure}. The python-configure macros allow for this by -defining Python as a language within Autoconf. You then would proceed -to write test programs as you would in any other language that -Autoconf supports like C. - -@example -AC_LANG_PUSH(Python)[] -AC_RUN_IFELSE([AC_LANG_PROGRAM([dnl -# some code here -import foo -], [dnl - # some more code here - foo.bar() -])], [ACTION-IF-SUCCESSFUL], [ACTION-IF-FAILED]) -AC_LANG_POP(Python)[] -@end example - -The first argument to @code{AC_LANG_PROGRAM} is the so-called -``prolog'', and typically will contain your @code{import} statements -or function definitions. The second argument contains the main body of -the program, which will be in the scope of an @code{if __name__=="__main__":} -block. So, you must be sure to indent the code appropriately. - -@node Using Sphinxbuild to build documentation, , Writing test programs, Using python-configure -@section Using Sphinxbuild to build documentation - -Using python-configure and Autoconf to test for other tools is quite -easy. For example, many Python packages use Sphinxbuild to build their -documentation.
