Even though jumping from 2.7.3 to 2.7.6 looks like a minor version bump, it is in fact a fairly significant one, because a good number of changes to help cross-compilation have been merged into Python upstream. Therefore, most of our patches are affected by this change. In detail, this commit: * Renames all the patches to follow the naming convention of patches in Buildroot: the patch file names should not have any version number. * The patches numbered above 100, that add configuration options to disable certain modules of the Python standard library, are only renamed and slightly adapted, they didn't change that much. * The patches numbered below 100 are almost entirely rewritten: many of the cross-compilation problems that used to exist in Python 2.7.3 no longer exist, and the number of remaining problems is smaller, and can be fixed with smaller patches.

Fix get_python_inc() for cross-compilation
|
|
|
|
When we are cross compiling, doing os.path.dirname(sys.executable) to
|
|
get the build directory is incorrect, because we're executing the host
|
|
Python to build things for the target. Instead, we should use the
|
|
project_base variable.
|
|
|
|
This fixes cross-compilation, which was adding incorrect header paths
|
|
pointing to the location where the host Python was built:
|
|
|
|
/home/thomas/projets/buildroot/output/host/usr/bin/arm-none-linux-gnueabi-gcc -fPIC -fno-strict-aliasing \
|
|
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -Os -DNDEBUG -g -O3 -Wall -Wstrict-prototypes \
|
|
-I/usr/include -I. -IInclude -I./Include -I/home/thomas/projets/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/include \
|
|
-I/home/thomas/projets/buildroot/output/host/usr/bin/Include -I/home/thomas/projets/buildroot/output/host/usr/bin \
|
|
-c /home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/_struct.c \
|
|
-o build/temp.linux2-arm-2.7/home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/_struct.o
|
|
|
|
This patch allows to fix the
|
|
/home/thomas/projets/buildroot/output/host/usr/bin/Include and
|
|
/home/thomas/projets/buildroot/output/host/usr/bin paths that are
|
|
incorrectly added to the header paths.
