Other changes include:
- Refreshing all necessary patches for 3.7.0
- Add a hash for the license file.
- Python no longer has it's own internal libffi, as such, host-libffi
is now required to build host-python3, and is added as a
dependency.
- Drop PYTHON3_LIBTOOL_PATCH = NO, since there is no longer any
internal libffi copy that was causing the libtool patching process
to fail.
- A new core module "uuid" is now is added in the Config.in file, and
relies on util-linux's uuid library.
- Also, a new patch: 0030-Fix-cross-compiling-the-uuid-module.patch
is required to fix compiling the uuid module, because the include
directory search path for uuid.h is hardcoded to /usr/include/uuid,
which causes an "unsafe for cross-compilation" error during
compiling if the host pc has uuid headers installed.
- 0031-Add-an-option-to-disable-uuid-module.patch is added to allow
disabling the Python3 UUID module, so that when
BR2_PACKAGE_PYTHON3_UUID is disabled by the UUID library is
present, the uuid Python module is not built, as expected.
- 0032-fix-building-on-older-distributions.patch is added to change
os.replace by os.rename in the update_file.py script to fix
building on older Linux distributions that have older versions of
python that don't include os.replace.
os.rename acts in the same way as os.replace, but is cross-platform
compatible. Because Buildroot is guaranteed to be built in a POSIX
environment, it is safe to change replace to rename.

Subject: [PATCH] Add infrastructure to disable the build of certain extensions
|
|
|
|
Some of the extensions part of the Python core have dependencies on
|
|
external libraries (sqlite, tk, etc.) or are relatively big and not
|
|
necessarly always useful (CJK codecs for example). By extensions, we
|
|
mean part of Python modules that are written in C and therefore
|
|
compiled to binary code.
|
|
|
|
Therefore, we introduce a small infrastructure that allows to disable
|
|
some of those extensions. This can be done inside the configure.ac by
|
|
adding values to the DISABLED_EXTENSIONS variable (which is a
|
|
word-separated list of extensions).
|
|
|
|
The implementation works as follow :
|
|
|
|
* configure.ac defines a DISABLED_EXTENSIONS variable, which is
|
|
substituted (so that when Makefile.pre is generated from
|
|
Makefile.pre.in, the value of the variable is substituted). For
|
|
now, this DISABLED_EXTENSIONS variable is empty, later patches will
|
|
use it.
|
|
|
|
* Makefile.pre.in passes the DISABLED_EXTENSIONS value down to the
|
|
variables passed in the environment when calling the setup.py
|
|
script that actually builds and installs those extensions.
|
|
|
|
* setup.py is modified so that the existing "disabled_module_list" is
|
|
filled with those pre-disabled extensions listed in
|
|
DISABLED_EXTENSIONS.
|
|
|
|
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
|
|
then extended by Thomas Petazzoni
|
|
<thomas.petazzoni@free-electrons.com>.
