NAME
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
o build depend on dh-python,
o build depend on all supported Python interpreters, pybuild will use
it to create a list of interpreters to build for. Recognized depen-
dencies:
o python3-all-dev - for Python extensions that work with Python
3.X interpreters,
o python3-all-dbg - as above, add this one if you're building -dbg
packages,
o python3-all - for Python modules that work with Python 3.X in-
terpreters,
o python3-dev - builds an extension for default Python 3.X inter-
preter (useful for private extensions, use python3-all-dev for
public ones),
o python3 - as above, used if headers files are not needed to
build private module,
o python-all-dev - for Python extensions that work with obsolete
Python 2.X interpreters,
o python-all-dbg - as above, add this one if you're building -dbg
packages,
o python-all - for Python modules that work with obsolete Python
2.X interpreters,
o pypy - for PyPy 2.X interpreter.
o add --buildsystem=pybuild to dh's arguments in debian/rules,
o 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
o 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:
o PYBUILD_OPTION_VERSIONED_INTERPRETER (f.e. PY-
BUILD_CLEAN_ARGS_python3.2)
o PYBUILD_OPTION_INTERPRETER (f.e. PYBUILD_CONFIG-
URE_ARGS_python3-dbg)
o 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
o {version} will be replaced with current Python version, you can also
use {version.major}, {version.minor}, etc.
o {interpreter} will be replaced with current interpreter, you can also
use {interpreter.include_dir}
o {dir} will be replaced with sources directory,
o {destdir} will be replaced with destination directory,
o {home_dir} will be replaced with temporary HOME directory, where
plugins can keep their data (.pybuild/interpreter_version/ by de-
fault),
o {build_dir} will be replaced with build directory
o {install_dir} will be replaced with install directory.
o {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
o {version} will be replaced with current Python version,
o {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
o --disable test/python2.5-dbg - disables tests for python2.5-dbg
o --disable '2.4 2.7' - disables all actions for version 2.4 and 2.7
o PYBUILD_DISABLE_python2=1 - disables all actions for Python 2.X
o PYBUILD_DISABLE_python3.3=test - disables tests for Python 3.3
o PYBUILD_DISABLE=test/python3.3 - same as above
o 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
