## gcc-11 With gcc-11, `pip install` also fails. (kind of similar to gcc-12)

I will test again, using bc222ec17b08fb6ea4f35ceb2bbb682076f7a7da

On my ubuntu 24.04 notebook, using commit bc222ec17b08fb6ea4f35ceb2bbb682076f7a7da `pip install . -vv` finish without error. But when I try to import cytnx from python, I got the runtime error: ````...

Thisis to confirm that: Using bc222ec , on macOS 15.6, `pip install .` is successful when I use * Apple clang version 17.0.0 * Homebrew clang version 20.1.7

@IvanaGyro Can you help to provide some documentation for the scikit-build-core/pip install? Especially about how to pass configurations. For example, if I do ```` pip install . -vv \ --config-settings...

Now I remember. In my Ubuntu 24.04, `libopenblas.so` does NOT contain `LAPACKE_*`. There is a separate `liblapacke.so` which do contain `LAPACKE_*`. ```` nm -gD /lib/x86_64-linux-gnu/libopenblas.so |grep LAPACKE ```` ```` nm...
