Bug reproduced with python 3.6.3.

Bug reproduced with python 3.7
I think the libffi cross build installs into the wrong location, or at least into a location poorly suited to the task at hand. My workaround for this, which worked for me for aarch64 and python3.6, is to create two symlinks: ln -sv ../lib/libffi/include/ffi.h /usr/aarch64-unknown-linux-gnu/usr/include/ffi.h ln -sv ../lib/libffi/include/ffitarget.h /usr/aarch64-unknown-linux-gnu/usr/include/ffitarget.h If those paths aren't the exact ones on your host/target combination, find them with: find /usr/aarch64-unknown-linux-gnu -name "ffi.h"
py3.6 > warning: building with the bundled copy of libffi is deprecated on this platform. It will not be distributed with Python 3.7 py3.7 > checking for --with-system-ffi... yes > configure: WARNING: --with(out)-system-ffi is ignored on this platform py3.8 > configure: WARNING: --with(out)-system-ffi is ignored on this platform So it seems that at least since py3.7, the additional handling in the ebuilds for making sure things use system libffi are redundant.
I can confirm this issue on python:3.8 It looks like the whole lib and include dirs discovery is broken for "setup.py build" when cross-compiling - it fails to build a few modules because "the necessary bits were not found" (sqlite3, zlib) I think that the most elegant way to fix this would be to use "--sysroot" parameter of the compiler/linker, setup.py already parses it and appends to search paths (this fixes the build), but that also affects build stage where libs/includes are already discovered correctly. Another option would be to patch SYSROOT discovery in setup.py So I am not sure which workaround is the best, any ideas? (In reply to Scott Howard from comment #5) > I think the libffi cross build installs into the wrong location, or at least > into a location poorly suited to the task at hand. I believe this behaviour is correct, it is explained in libffi ebuild, https://gitweb.gentoo.org/repo/gentoo.git/tree/dev-libs/libffi/libffi-3.3-r2.ebuild#n61
Created attachment 697809 [details, diff] patch to add --sysroot option to CFLAGS/LDFLAGS

For now the workaround in https://bugs.gentoo.org/633712#c5 still works. It would still be great for it to be fixed.
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=3478cabb5f94e9d90ae1ed9e3f7909a1146aa471 commit 3478cabb5f94e9d90ae1ed9e3f7909a1146aa471 Author: Sam James <sam@gentoo.org> AuthorDate: 2022-12-06 19:35:41 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2022-12-06 19:38:51 +0000 dev-lang/python: disable _ctypes, _crypt for cross (CBUILD) Python * Use a hack to deduce libdir to nudge the build system in the right direction because get_libdir can't handle BROOT/CBUILD right now. * Disable _ctypes (libffi) and _crypt (lib(x)crypt) modules for cross (CBUILD) Python as they're not needed and Python struggles to find the libraries correctly. This avoids an issue where setup.py can't handle deducing libdir (or even being passed it) for cross-compilation. Fortunately, cpython is migrating away from setup.py to autotools. Note that this isn't the same as what bug 633712 would've been at the time it was reported, but it certainly showed up the same way on more modern Pythons since we introduced the CBUILD part a few months ago.
