Hi everyone, we have a reocurring problem with multiple providers of libraries built as serial and openMPI(1-4)/MVAPICH/... flavors. Currently, both the serial and e.g. openMPI4 flavors provide the exact same resolvables, e.g. "libsundials_sunlinsolklu.so.4.2.0()(64bit)" [1]. This is then manually fixed up on a case-by-case basis by manually specifying the default package. Fedora solves this problem by adding the MPI flavor to the resolvable, e.g. "libfoo.so()(64bit)(openmpi-x86_64)". For details, see [2][3]. I would propose for (open)SUSE to follow this notation, and finally get rid of the manual workarounds. Kind regards, Stefan [1] https://build.opensuse.org/package/binary/science/sundials:openmpi4/ openSUSE_Tumbleweed/x86_64/libsundials4-openmpi4-6.2.0-19.1.x86_64.rpm [2] https://fedoraproject.org/wiki/Changes/RpmMPIReqProv [3] https://packages.fedoraproject.org/pkgs/rpm-mpi-hooks/rpm-mpi-hooks/ index.html
