My users are not allowed to change alternatives or install/remove packages. The
important thing to note is that it has to work with both openblas and blas
simultaneously for different users. What I'm trying to use alternatives for is
ensuring that openblas is the default when they just specify -lblas -llapack
when linking. Then the people who require the stability of reference blas need
to specify it with -L/usr/lib64/libblas.so.3.4.2
I agree that "update-alternatives --config libblas.so" would make more sense,
but currently it seems "update-alternatives --config libblas.so.3" is the one
used. Perhaps Debian is to blame for this:
https://wiki.debian.org/DebianScience/LinearAlgebraLibraries .
Anyway, typing in "update-alternatives --config libblas.so.3" gives me
(correctly) a choice between the various blas versions I have installed, and
works perfectly when I override the blas-devel symlinks so it's
libblas.so->libblas.so.3->libblas.so.3.4.2 . Unfortunately this gets
overwritten whenever blas-devel is updated.
