Hello,
I've recently encountered the following test failure when I wanted to run the
upstream Cython testusite on Fedora CI.
======================================================================
ERROR: runTest (__main__.CythonRunTestCase.runTest)

distutils.errors.LinkError: command '/usr/bin/g++' failed with exit code 1
There were 4 failures like this (all pythran_numpy related).
I was clueless as to why is this failing. I was trying to make the tests tell
me more.
After long digging I ended up modifying
/usr/lib/python3.12/site-packages/setuptools/_distutils/spawn.py in a test
container directly to always make this conditional False:
https://github.com/pypa/setuptools/blob/v69.1.0/setuptools/_distutils/spawn.py#L61
This turned:
distutils.errors.DistutilsExecError: command '/usr/bin/g++' failed with exit
code 1
Into:
distutils.errors.DistutilsExecError: command ['/usr/bin/g++', ...] failed
with exit code 1
Then, I was able to rerun the failed g++ command manually to see the actual
linker error (missing flexiblas).
However, the experience was far from ideal.
Would it be possible (and desired) to modify the tests to actually print out
the compiler/linker errors when they happen?
Or perhaps this already is possible, but I am not doing it correctly? (I tried
--no-capture, but no dice.)
Thanks,
