Originally posted by @Carltoffel in #859 (comment) :

          When I use the MPI metapackage with `use mpi`, I also have to use `build.external-modules = ["mpi"]`. Is this behaviour intended? Otherwise, I get:

 + which mpiexec
/usr/bin/mpiexec
<ERROR> *cmd_run* Targets error: Unable to find source for module dependency: "mpi" used by "app/main.f90"

In the example_packages directory, import mpif.h is used, which circumvents this. Which method is preferred?

The text was updated successfully, but these errors were encountered:
