py-scipy seems to be broken with GCC: error: '__and_' was not declared in this scope; did you mean 'std::__and_'? etc.

Possibly related: ​https://gcc.gnu.org/pipermail/gcc-bugs/2022-May/787736.html

[diochnos]

I am not sure if this is related or if it is a separate issue, but I had an issue installing py310-scipy when I tried to install py310-scikit-learn and the installation failed. I am attaching a file with the log.

[barracuda156]

16. S. Above log has Architecture: unsupported because py-numpy and friends have a defunct arch detection, but it is not the reason for the error, it seems.

[greyhare]

I ran into this when building py311-scipy+gcc13+openblas. The default variants +gfortran+openblas result in bug #68329.

[barracuda156]

This is due to using an old Boost. No such an error with Boost 1.81.

[barracuda156]

Another, unrelated issue, is that legacysupport cmath conflicts with GCC headers and breaks isinf and isnan. I will try to fix that too.

[barracuda156]

UPD. Okay, I have fixed the build finally. (Arch detection on PowerPC not yet, but it matters only for optimizations, apparently.)
