Build fails on GCC 15 #16
Description
Not sure what the exact root cause is, but recently I've started having issues building astLib. I'm running on Fedora 42 with Python 3.12.12 in a venv and GCC 15:
~$ python -V
Python 3.12.12
~$ gcc --version
gcc (GCC) 15.2.1 20251111 (Red Hat 15.2.1-4)The steps I do to recreate the issue:
uv venv testenv --python=python3.12
<source testenv>
uv pip install astlibwhich throws a bunch of warning: old-style function definition and error: too many arguments to function errors. Just to be sure I also tried it without uv, but I see the same crash with plain pip.
Finally, I tried modifying setup.py to force it to use a separate GCC14 installation, after which it builds and installed just fine, so I'm guessing it has to do with GCC 15 somehow.
Build failure output with GCC 15:
~$ uv pip install astlib
