opensuse-tumbleweed: sagelib build fails

[mkoeppe]

As reported in https://groups.google.com/g/sage-devel/c/81unMG60MyU/m/JdMKMFOSBQAJ

Workaround: export CFLAGS="${CFLAGS} -Wno-error=return-type" (https://groups.google.com/g/sage-devel/c/81unMG60MyU/m/TfBT8KOsBQAJ)

This is caused by strict compiler flags leaking from the opensuse python3 package into user packages via sysconfig/distutils.
Same mechanism as the failures with misconfigured python3 in #31132 (homebrew), #33078 (cygwin), #32531 (pyenv)

Upstream issue:

Changed upstream from Not yet reported upstream; Will do shortly. to Reported upstream. No feedback yet.

For our part, we already warn when the sysconfig flags contain -I or -L. We could do the same for -Werror.

[mkoeppe]

comment:3

Good idea.

[mkoeppe]

comment:4

In contrast to the trouble with -I and -L (for which the sysconfig-provided flags are coming first and therefore cannot be overridden), in this case we can work around it by adding the -Wno-error to our flags for the affected extension modules...

Ok, that's a better idea, I'm trying it.

Need to check though if this flag works with ancient compilers that we still support

The upstream bug is already fixed in fflas-ffpack-2.4.3. Repology says that tumbleweed is at 2.5.0. I wonder what version the reporter is using? Maybe we just bump the minimum version in spkg-configure.m4 up from 2.4.0 to 2.4.3. Again according to repology that shouldn't hurt anyone.

Nevermind. The github tag doesn't match the release tarball.

comment:11

Anyway, I've tried to clobber my sysconfig but the build still succeeded. My system header is missing the return value. So I wonder why it worked:

sage: import sysconfig
sage: sysconfig.get_config_var('CFLAGS')
'-Werror=return-type -Wno-unused-result -Wsign-compare -DNDEBUG -O2 -pipe -march=native -fwrapv'
sage: import distutils.sysconfig as dsc
sage: dsc.get_config_var('CFLAGS')
'-Werror=return-type -Wno-unused-result -Wsign-compare -DNDEBUG -O2 -pipe -march=native -fwrapv'

Perhaps a sufficiently smart compiler has optimized the issue away?

tox -e docker-ubuntu-trusty-standard succeeded, so I think we're in good shape

Not this time, I used -O0.

comment:15

I haven't figured out how to get cython to show me WTF it's actually doing yet, but watching ps auxwww, I can see that the sysconfig flags aren't being used while it's compiling pyx files.

Is that using standard Sage Python packages, or using some system python packages?

It turns out that the python on Gentoo is already patched to avoid this very issue. Ugh.

Rebuilt with the python3 SPKG, and now my sysconfig changes are visible. But somehow I'm able to compile the file that was causing the OP's problem, e.g.:

matrix_modn_dense_double.cpp includes fflas-ffpack.h, which includes fflas/fflas.h, which includes fflas_level3.inl, which includes the pfgemm function without a return value.

I would think it is sufficient to reproduce the error on the reported platform and confirm that the patch fixes it. Little point on trying to reproduce on a different platform.

I finally got it to fail using the fflas_ffpack SPKG. Maybe it has something to do with the autotune, who knows. Anyway, the patch works. I added some comments at the top of the file. Feel free to positive review after checking it.
