Fixing sage build problems in the AI era

[Kwankyu Lee]

Hi,

Today I attempted to fix my sage dev install, which has been long left broken on my macbook.

Since I am incapable of fixing any build problem that I would encounter for myself and it is the AI era, I opened the sage dev directory into Google Antigravity and ran the old and friendly "./bootstrap && ./configure && make -j4" after "git pull" and "make distclean" in the terminal embedded to Antigravity.

As I expected, "make" soon stopped with the error message:

[fflas_ffpack-2.5.0+sage-2024-05-18b] [spkg-install] clang++: error: unsupported option '-fopenmp'

I told the AI agent to fix the issue. Then the AI agent worked a while and finally succeeded in fixing the problem. The PR 

https://github.com/sagemath/sage/pull/42200 

is its outcome. After this, there were a few more stops, but each of which was solved by the AI agent. Those were caused by peculiarities of my local environment. So no PR is needed.

Now I have a working sage install on my macbook. I am happy with the AI buddy.

Thanks for reading.

We have a fix for the OpenMP macOS issue which is currently being held up by a bug in Meson.
#41626

They should have a new release any day now, then we can address this properly.
