Hi,
sorry I am using tumbleweed.
yes was my mistake in mixing things but that showed the problem.
installing this libscalapack2-openmpi4
pulls the openmpi3 and not 4/ Not an issue for me since i use hpc but
may be for others.
Regards,
Alin

Hi Alin,
please specify what system you are using (Leap<version>, Tumbleweed ...). It seems you are mixing HPC (openmpi4-gnu-hpc-devel) and non-HPC packages. Moreover, there is no scalapack-openmpi4 (not even among the non-HPC packages).
There is a bit of a problem with MPI depenendencies with non-HPC packages. It seems like both openmpi3 and 4 provide libmpi.so.40()(64bit). @Nicolas - is this correct?
Yes they do. But in theory, packages depending on a specific MPI version like this should require the right openmpi, not just the libmpi.so WHich lapack does not seem to be doing/ BuildRequires: %{mpi_flavor}%{?mpi_ext}-devel
It's only a BuildRequires but a Requires: %{mpi_flavor}%{?mpi_ext}-libs is also needed.
Scratch some of that (it works but there is a newer/better way) openmpi* packages were cleaned up some time back. What should be done for all openmpi (at least non hpc) dependant packages is: BuildRequires: openmpi<N>-macros-devel
It'll provide the macros: %setup_openmpi # (Load the orpper mpivars.sh) %openmpi_requires # ( Add the right Requires:..... for the openmpi package) %openmpi_devel_requires # same but for devel packages)
Also for using the "default" version of openmpi (currently openmpi2), you can juste BuildRequires: openmpi-macros-devel. It'll pull the macros from the default version so there is no need to specify which one and it can be changed more easily when we decide to go to openmpi 3 or 4 by default.

For the HPC variants this has been fixed. If both openmpi3 and openmpi4 provide the libmpi.so.4 ABI, then you will have to install openmpi4-libs explicitly, I'm afraid - or use the HPC variant of scalapack.
Cheers, Egbert.

Hi.
I try to install openmpi4 but somehow openmpi3 is pulled see below.
