I'll look into it.Hiya, I recently packaged up nest[0] which is widely used in the computational neuroscience research community. The review ticket is here[1], and the copr builds are here[2]. Even though the rpm builds perfectly, dnf won't install them from the copr. This is what I get:[asinha@cs-as14aho-2-herts-ac-uk ~]$ rpm -q --provides mpich libmpi.so.12()(64bit)(mpich-x86_64) libmpicxx.so.12()(64bit)(mpich-x86_64) libmpifort.so.12()(64bit)(mpich-x86_64) mpi mpich = 3.1.4-5.fc23 mpich(x86-64) = 3.1.4-5.fc23 mpich2 = 3.0.1[asinha@cs-as14aho-2-herts-ac-uk ~]$ sudo dnf install nest-mpich pynest -y Error: nothing provides libmpi.so.12()(64bit) needed by pynest-2.8.0-1.gitdc21fdc.fc23.x86_64. nothing provides libmpi.so.12()(64bit) needed by nest-mpich-2.8.0-1.gitdc21fdc.fc23.x86_64 (try to add '--allowerasing' to command line to replace conflicting packages)[asinha@cs-as14aho-2-herts-ac-uk ~]$Would someone know what I'm doing wrong here? :/
$MPI_HOME = %{_libdir}/$MPI_NAME
$MPI_FORTRAN_MOD_DIR = %{_libdir}/gfortran/modules/$MPI_NAME
$MPI_PYTHON_SITEARCH = %{python2_sitearch}/$MPI_NAME
$MPI_PYTHON3_SITEARCH = %{python3_sitearch}/$MPI_NAME
where $MPI_NAME is openmpi or mpich.
So you should install the mpi-enabled pynest in the appropriate
$MPI_PYTHON_SITEARCH directory.
