@jrohwer

When building PETSc (more specifically, petsc4py), one test (ex100 from ksp) will fail if a previous (major) version is installed. I could not figure out why this happens. The solution would be to build in a clean root (which is a little bit complicated due to dependency on other AUR packages) or simply uninstall the old version before.

Any help to solve this issue is welcomed.

According to this log. petsc can not be compiled without scotch. Happily the binaries are available in arch4edu repository. See https://mirror.sunred.org/arch4edu/x86_64

@smp: scotch is now build with cmake, which required some changes on the petsc side. Did you try to update scotch first?

As described previously, building PETSc without the optional Scotch dependency fails. It looks like the issue can be fixed by replacing the following line in file test_optdepends.sh

if [ -d "${SCOTCH_DIR}" ]; then

with

if [ -f /usr/include/scotch.h ]; then

Can we add superlu_dist as optional dependency? Same as for superlu:

if [ -f "/usr/lib/pkgconfig/superlu_dist.pc" ]; then
  CONFOPTS="${CONFOPTS} --with-superlu_dist-lib=-lsuperlu_dist --with-superlu_dist-include=/usr/include/superlu_dist"
fi

@lahwaacz: I'm just trying to understand what's going on and find a solution, not workarounds. If ssh is a dependency for openmpi, it has to be solved in the respective package. If all PETSc applications require it, it is a dependency. But checkdepends seems to be a quick fix that should not be in the official PKGBUILD

@MartinDiehl petsc currently can't be built in a clean chroot without openssh in checkdepends. The solution for more problems is more workarounds, not delaying previous workarounds.

@lahwaacz and @carlosal1015: I think then it makes sense to apply the same fix as for MUMPS.

However, it seems that ssh is not the problem the only problem. At least on my setup, I cannot run MPI applications if WiFi and ethernet is disabled. I understand that MPI is meant to work over network, but it would be nice if one could use the same executable on a machine without ssh and a network connection.

@MartinDiehl The openssh problem is reported in https://bugs.archlinux.org/task/75535 but carlosal1015's comment was about adding it to checkdepends, not depends. FWIW it's the same problem that you've recently fixed in https://aur.archlinux.org/cgit/aur.git/commit/?h=mumps&id=05532ed6645296c32c6e9c247024959aa4715bcc

@carlosal1015: I don't think that PETSc has a dependency on openssh. Maybe openMPI has (there are some ongoing discussions).
