pybuild

invokes various build systems for requested Python versions in order to build modules and extensions

SYNOPSIS

pybuild [ACTION] [BUILD SYSTEM ARGUMENTS] [DIRECTORIES] [OPTIONS]

DEBHELPER COMMAND SEQUENCER INTEGRATION

• build depend on dh-python, • build depend on all supported Python interpreters, pybuild will use it to create a list of interpreters to build for. Recognized depen‐ dencies: • python3-all-dev - for Python extensions that work with Python 3.X interpreters, • python3-all-dbg - as above, add this one if you're building -dbg packages, • python3-all - for Python modules that work with Python 3.X in‐ terpreters, • python3-dev - builds an extension for default Python 3.X inter‐ preter (useful for private extensions, use python3-all-dev for public ones), • python3 - as above, used if headers files are not needed to build private module, • python-all-dev - for Python extensions that work with obsolete Python 2.X interpreters, • python-all-dbg - as above, add this one if you're building -dbg packages, • python-all - for Python modules that work with obsolete Python 2.X interpreters, • pypy - for PyPy 2.X interpreter. • add --buildsystem=pybuild to dh's arguments in debian/rules, • if more than one binary package is build: add debian/python-foo.in‐ stall files, or export PYBUILD_NAME=modulename (modulename will be used to guess binary package prefixes), or export PYBUILD_DESTDIR env. variables in debian/rules • add --with=python3 or --with=python3,python2,pypy to dh's arguments in debian/rules (see proper helper's manpage for more details) or add dh-sequence-python3 (dh-sequence-python2 for Python 2.X, dh-se‐ quence-pypy for PyPy) to Build-Depends debian/rules file example: #! /usr/bin/make -f export PYBUILD_NAME=foo %: dh $@ --with python2,python3 --buildsystem=pybuild

OPTIONS

Most options can be set (in addition to command line) via environ‐ ment variables. PyBuild will check: • PYBUILD_OPTION_VERSIONED_INTERPRETER (f.e. PY‐ BUILD_CLEAN_ARGS_python3.2) • PYBUILD_OPTION_INTERPRETER (f.e. PYBUILD_CONFIG‐ URE_ARGS_python3-dbg) • PYBUILD_OPTION (f.e. PYBUILD_INSTALL_ARGS) optional arguments -h, --help show this help message and exit -v, --verbose turn verbose mode on -q, --quiet doesn't show external command's output -qq, --really-quiet be quiet --version show program's version number and exit ACTION The default is to build, install and test the library using detected build system version by version. Selecting one of following actions, will invoke given action for all versions - one by one - which (con‐ trary to the default action) in some build systems can overwrite previous results. --detect return the name of detected build system --clean clean files using auto-detected build system specific methods --configure invoke configure step for all requested Python versions --build invoke build step for all requested Python versions --install invoke install step for all requested Python versions --test invoke tests for auto-detected build system --list-systems list available build systems and exit --print print pybuild's internal parameters TESTS unittest's discover from standard library (available in Python 2.7 and >= 3.2) is used in test step by default. --test-nose use nose module in test step, remember to add python-nose and/or python3-nose to Build-Depends --test-pytest use pytest module in test step, remember to add python-pytest and/or python3-pytest to Build-Depends --test-tox use tox command in test step, remember to add tox to Build-Depends. Requires tox.ini file testfiles Tests are invoked from within build directory to make sure newly built files are tested instead of source files. If test suite re‐ quires other files in this directory, you can list them in de‐ bian/pybuild.testfiles file (you can also use debian/py‐ build-pythonX.testfiles or debian/pybuild-pythonX.Y.testfiles) and files listed there will be copied before test step and removed be‐ fore install step. By default only test and tests directories are copied to build directory. BUILD SYSTEM ARGUMENTS Additional arguments passed to the build system. --system=custom requires complete command in --foo-args parameters. --before-clean COMMAND invoked before the clean command --clean-args ARGUMENTS arguments added to clean command generated by build sys‐ tem plugin --after-clean COMMAND invoked after the clean command --before-configure COMMAND invoked before the configure command --configure-args ARGUMENTS arguments added to configure command generated by build system plugin --after-configure COMMAND invoked after the configure command --before-build COMMAND invoked before the build command --build-args ARGUMENTS arguments added to build command generated by build sys‐ tem plugin --after-build COMMAND invoked after the build command --before-install COMMAND invoked before the install command --install-args ARGUMENTS arguments added to install command generated by build system plugin --after-install COMMAND invoked after the install command --before-test COMMAND invoked before the test command --test-args ARGUMENTS arguments added to test command generated by build system plugin --after-test COMMAND invoked after the test command variables that can be used in ARGUMENTS and COMMAND • {version} will be replaced with current Python version, you can also use {version.major}, {version.minor}, etc. • {interpreter} will be replaced with current interpreter, you can also use {interpreter.include_dir} • {dir} will be replaced with sources directory, • {destdir} will be replaced with destination directory, • {home_dir} will be replaced with temporary HOME directory, where plugins can keep their data (.pybuild/interpreter_version/ by de‐ fault), • {build_dir} will be replaced with build directory • {install_dir} will be replaced with install directory. • {package} will be replaced with suggested package name, if --name (or PYBUILD_NAME) is set to foo, this variable will be replaced to python-foo, python3-foo or pypy-foo depending on interpreter which is used in given iteration. DIRECTORIES -d DIR, --dir DIR set source files directory - base for other relative dirs [by default: current working directory] --dest-dir DIR set destination directory [default: debian/tmp] --ext-dest-dir DIR set destination directory for .so files --ext-pattern PATTERN regular expression for files that should be moved if --ext-dest-dir is set [default: .so(.[^/]*)?$] --ext-sub-pattern PATTERN regular expression for part of path/filename matched in --ext-pattern that should be removed or replaced with --ext-sub-repl --ext-sub-repl PATTERN replacement for matches in --ext-sub-pattern --install-dir DIR set installation directory [default: .../dist-packages] --name NAME use this name to guess destination directories (depending on interpreter, "foo" sets debian/python-foo, de‐ bian/python3-foo, debian/python3-foo-dbg, etc.) variables that can be used in DIR • {version} will be replaced with current Python version, • {interpreter} will be replaced with selected interpreter. LIMITATIONS -s SYSTEM, --system SYSTEM select a build system [default: auto-detection] -p VERSIONS, --pyver VERSIONS build for Python VERSIONS. This option can be used multiple times. Versions can be separated by space character. The default is all Python 3.X supported versions. -i INTERPRETER, --interpreter INTERPRETER change interpreter [default: python{version}] --disable ITEMS disable action, interpreter, version or any mix of them. Note that f.e. python3 and python3-dbg are two different in‐ terpreters, --disable test/python3 doesn't disable python3-dbg's tests. disable examples • --disable test/python2.5-dbg - disables tests for python2.5-dbg • --disable '2.4 2.7' - disables all actions for version 2.4 and 2.7 • PYBUILD_DISABLE_python2=1 - disables all actions for Python 2.X • PYBUILD_DISABLE_python3.3=test - disables tests for Python 3.3 • PYBUILD_DISABLE=test/python3.3 - same as above • PYBUILD_DISABLE=configure/python3 2.4 pypy - disables configure ac‐ tion for all python3 interpreters, all actions for version 2.4, and all actions for pypy
