Issue

After installing the gcc package (gcc 12), attempting to compile C11 code that uses the static_assert macro that should be defined by assert.h fails.

echo -e "#include <assert.h>\nstatic_assert(1);" > test.c
gcc -std=c11 -c test.cc
t.c:2:15: error: expected declaration specifiers or '...' before numeric constant
    2 | static_assert(1);
      |               ^

The root cause seems to be that the version of assert.h in the sysroot is very old and does not support C11 static_assert.

This needs a newer sysroot (presumably RHEL 8 clone like alma), see conda-forge/conda-forge.github.io#1432

No, this just needs CentOS 7. You can do conda install sysroot_linux-64=2.17

I've also been running into this while building iree. I could work around it by installing sysroot_linux-64 2.17
Do I understand correctly that we can't currently build C11 projects with the default sysroot_linux package?
Is there any way this could be fixed? Took me a day to figure this out...
