Description Giuseppe Ghibò 2021-01-21 21:59:24 CET 
Current openblas library comes with 4 flavours (plain, openmp, threads, serial), however for the extra flavours there were used package names not containing the "openblas" string, e.g.:

lib64threads0
lib64openmp0
lib64serial0

for libopenblasp.so, libopenblaso.so and so on. These are pretty generic names and can be confused with other libraries that have a similar name but do different stuff (thread, openmp, serial). I suggest to rename to something like:

lib64openblasthreads0
lib64openblasopenmp0
lib64openblasserial0

or alternatively

lib64openblasp0
lib64openblaso0
lib64openblass0

I attach the two alternative diff for the .spec file.

This seems a sensible request, thank you for it.
Openblas is new for Mageia 8. Searching for it in rpmdrake just shows:
 lib64openblas-devel
 lib64openblas-static-devel
 openblas
 openblas-srpm-macros
Even searching for just 'blas' does not show the three libs in question; so how one would discoverthe others is puzzling.

Name        : openblas
Summary     : An optimized BLAS library based on GotoBLAS2
Even more curiously, this obvious package 'openblas' contains just /usr/share/doc/* and /usr/share/licenses/*, NO visible library. Is the 'plain' variant: "4 flavours (plain, openmp, threads, serial)" disguised under yet another lib64... package name?

Name        : lib64threads0
Summary     : An optimized BLAS library based on GotoBLAS2, pthreads version
/usr/lib64/libopenblasp-r0.3.12.so
/usr/lib64/libopenblasp.so.0

Name        : lib64openmp0
Summary     : An optimized BLAS library based on GotoBLAS2, OpenMP version
/usr/lib64/libopenblaso-r0.3.12.so
/usr/lib64/libopenblaso.so.0

Name        : lib64serial0
Summary     : An optimized BLAS library based on GotoBLAS2, serial version
/usr/lib64/libopenblas-r0.3.12.so
/usr/lib64/libopenblas.so.0

In fact there are very many libraries (excluding devel ones) shown by
 $ urpmf libopenblas | grep -v devel
Yet I cannot identify therein the 'plain' variant, if it exists.

Assigning this to Thierry as the SRPM maintainer.
