Comment (by massonseb):
>Just curious. *why* are you trying to install using gcc12 ? Using gcc to
build c++ sources is problematic on macOS, due to the potential for mixing
incompatible c++ runtimes (libstdc++ versus libc++). Generally speaking
its better to just stick to the defaults, which in this case work.
I need to compile a fortran code with with MPI. This code also needs
NetCDF that must be linked with an hdf5 library compiled with `--enable-
parallel` (so the NetCDF command `nc-config --has-parallel` returns
`yes`). \\
Having said that, I would like to try gcc and openmpi to compile my code.
\\
I thought (but I may be wrong) that I should use gcc+openmpi to compile
NetCDF and HDF5, as I will use gcc+openmpi to compile my fortran code.
I am always afraid to mix-up libraries compiled with different compilers…
Another point that is not clear to me: \\
If I select `openmpi-gcc12-fortran` as the default version for mpi with
`sudo port select —set mpi openmpi-gcc12-fortran` Which openmpi is used
when doing `sudo port install hdf5 +openmpi`? is it openmpi-gcc12 that I
selected?
