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] Adjust library/header paths for cross-compilation
|
|
|
|
When cross-compiling third-party extensions, the get_python_inc() or
|
|
get_python_lib() can be called, to return the path to headers or
|
|
libraries. However, they use the sys.prefix of the host Python, which
|
|
returns incorrect paths when cross-compiling (paths pointing to host
|
|
headers and libraries).
|
|
|
|
In order to fix this, we introduce the _python_sysroot, _python_prefix
|
|
and _python_exec_prefix variables, that allow to override these
|
|
values, and get correct header/library paths when cross-compiling
|
|
third-party Python modules.
