BUG: OpenBSD/amd64 7.4 doesn't build from source due to missing -lcblas #25041
Description
Describe the issue:
Can't install numpy through pip, because the meson can't detect the blas and lapack correctly.
And I find there aren't any blas.pc and lapack.pc under the /usr/local/lib/pkgconfig.
Reproduce the code example:
pip install numpy==1.26.1Error message:
No response
Runtime information:
OpenBSD/amd 7.4
Python 3.10
Context for the issue:
The meson can't detect the blas and lapack in OpenBSD.

Thanks @DavidAlphaFox, but we'll need a bit more info than that to be able to help. Questions:

Yes I need build with BLAS/LAPACK.
BLAS and LAPACK comes from OpenBSD's pkg and the are all installed under /usr/local.
The system package manager doesn't generate the .pc under /usr/local/lib/pkgconfig

Thanks for the details. I'm working on a fix for this.
We don't have an OpenBSD CI job, but we do have a FreeBSD one since recently (here). That doesn't use BLAS though, so I guess we should add that.
Could you please share the exact
pkginvocation for how to install BLAS and LAPACK, including headers if there's a separate -dev package? That would save some trial and error in CI.DavidAlphaFox commentedon Nov 1, 2023
