Main Makefile targets
|
||||
---------------------
|
||||
|
||||
* ``make``: Build Python with the standard library.
|
||||
* ``make platform:``: build the ``python`` program, but don't build the
|
||||
standard library extension modules.
|
||||
* ``make profile-opt``: build Python using Profile Guided Optimization (PGO).
|
||||
You can use the configure :option:`--enable-optimizations` option to make
|
||||
this the default target of the ``make`` command (``make all`` or just
|
||||
``make``).
|
||||
make
|
||||
^^^^
|
||||
|
||||
* ``make test``: Build Python and run the Python test suite with ``--fast-ci``
|
||||
option. Variables:
|
||||
For the most part, when rebuilding after editing some code or
|
||||
refreshing your checkout from upstream, all you need to do is execute
|
||||
``make``, which (per Make's semantics) builds the default target, the
|
||||
first one defined in the Makefile. By tradition (including in the
|
||||
CPython project) this is usually the ``all`` target. The
|
||||
``configure`` script expands an ``autoconf`` variable,
|
||||
``@DEF_MAKE_ALL_RULE@`` to describe precisely which targets ``make
|
||||
all`` will build. The three choices are:
|
||||
|
||||
* ``TESTOPTS``: additional regrtest command line options.
|
||||
* ``TESTPYTHONOPTS``: additional Python command line options.
|
||||
* ``TESTTIMEOUT``: timeout in seconds (default: 20 minutes).
|
||||
* ``profile-opt`` (configured with ``--enable-optimizations``)
|
||||
* ``build_wasm`` (configured with ``--with-emscripten-target``)
|
||||
* ``build_all`` (configured without explicitly using either of the others)
|
||||
|
||||
* ``make buildbottest``: Similar to ``make test``, but use ``--slow-ci``
|
||||
option and default timeout of 20 minutes, instead of ``--fast-ci`` option
|
||||
and a default timeout of 10 minutes.
|
||||
Depending on the most recent source file changes, Make will rebuild
|
||||
any targets (object files and executables) deemed out-of-date,
|
||||
including running ``configure`` again if necessary. Source/target
|
||||
dependencies are many and maintained manually however, so Make
|
||||
sometimes doesn't have all the information necessary to correctly
|
||||
detect all targets which need to be rebuilt. Depending on which
|
||||
targets aren't rebuilt, you might experience a number of problems. If
|
||||
you have build or test problems which you can't otherwise explain,
|
||||
``make clean && make`` should work around most dependency problems, at
|
||||
the expense of longer build times.
|
||||
|
||||
|
||||
make platform
|
||||
^^^^^^^^^^^^^
|
||||
|
||||
Build the ``python`` program, but don't build the standard library
|
||||
extension modules. This generates a file named ``platform`` which
|
||||
contains a single line describing the details of the build platform,
|
||||
e.g., ``macosx-14.3-arm64-3.12`` or ``linux-x86_64-3.13``.
|
||||
|
||||
|
||||
make profile-opt
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
Build Python using profile-guided optimization (PGO). You can use the
|
||||
configure :option:`--enable-optimizations` option to make this the
|
||||
default target of the ``make`` command (``make all`` or just
|
||||
``make``).
|
||||
|
||||
|
||||
|
||||
make clean
|
||||
^^^^^^^^^^
|
||||
|
||||
Remove built files.
|
||||
|
||||
|
||||
make distclean
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
In addition to the the work done by ``make clean``, remove files
|
||||
created by the configure script. ``configure`` will have to be run
|
||||
before building again. [#]_
|
||||
|
||||
|
||||
make install
|
||||
^^^^^^^^^^^^
|
||||
|
||||
Build the ``all`` target and install Python.
|
||||
|
||||
|
||||
make test
|
||||
^^^^^^^^^
|
||||
|
||||
Build the ``all`` target and run the Python test suite with the
|
||||
``--fast-ci`` option. Variables:
|
||||
|
||||
* ``TESTOPTS``: additional regrtest command-line options.
|
||||
* ``TESTPYTHONOPTS``: additional Python command-line options.
|
||||
* ``TESTTIMEOUT``: timeout in seconds (default: 10 minutes).
|
||||
|
||||
|
||||
make buildbottest
|
||||
^^^^^^^^^^^^^^^^^
|
||||
|
||||
This is similar to ``make test``, but uses the ``--slow-ci``
|
||||
option and default timeout of 20 minutes, instead of ``--fast-ci`` option.
|
||||
|
||||
|
||||
make regen-all
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
Regenerate (almost) all generated files. These include (but are not
|
||||
limited to) bytecode cases, and parser generator file.
|
||||
``make regen-stdlib-module-names`` and ``autoconf`` must be run
|
||||
separately for the remaining `generated files <#generated-files>`_.
|
||||
|
||||
* ``make install``: Build and install Python.
|
||||
* ``make regen-all``: Regenerate (almost) all generated files;
|
||||
``make regen-stdlib-module-names`` and ``autoconf`` must be run separately
|
||||
for the remaining generated files.
|
||||
* ``make clean``: Remove built files.
|
||||
* ``make distclean``: Same than ``make clean``, but remove also files created
|
||||
by the configure script.
