cc1plus: all warnings being treated as errors
gmake[2]: *** [libmambapy/CMakeFiles/bindings.dir/build.make:96: libmambapy/CMakeFiles/bindings.dir/src/libmambapy/bindings/legacy.cpp.o] Error 1
I'm guessing 'SR.32262' is some kind of temporary variable. libmamba has taken the (perhaps admirable?) step of compiling with -Werror so it fails.
The errors are in mamba's code base afaict.
You should disable warnings as error, enforce C++ standard in CMakeLists.txt, ask upstream about C++17 warnings, or all the above.
But just to be sure it's gcc15 related can you also target F41?
I'm not entirely sure I understand all of your suggestions. I did
disable -Werror, but that led to the issue I reported in my other email.
I tried compiling with cmake -DCMAKE_CXX_STANDARD=17 ... but that did
not appear to make any difference.
I have reported issues upstream:
https://github.com/mamba-org/mamba/issues/3791 (the uninitialized warning)
https://github.com/mamba-org/mamba/issues/3809 (the python abort)
I'll note here as well that I see the same python abort in F41. The
uninitialized warning goes away though, and I get this instead:
/builddir/build/BUILD/libmamba-2.0.6-build/mamba-2.0.6/libmambapy/src/libmambapy/bindings/path_caster.hpp:17:16:
