I noticed that port hdf5-18 +openmpi +cxx is only EXPERIMENTAL. So I

sudo port install hdf5-18 +cxx +fortran +gcc45

and tried again

However, splash should build with hdf5-18+openmpi, it presumably needs some adjustment of the included paths.

doesn't look like this is a splash issue, seems that mpi.h is not being found in the include paths (presumably should be in /opt/local/include). The hdf5-18 Portfile, with +openmpi depends on port:openmpi, which presumably installs mpi.h to /opt/local/include. So I'm not sure what's going on here.

[danieljprice (Daniel Price)]

Just an update here, I can reproduce this at my end, but am still not sure what to do about it. Looks like the relevant file (mpi.h) is located in

/opt/local/include/openmpi/mpi.h

so this path would need to be in the include paths for splash for this to work. But why should the splash build have to specifically add -I${prefix}/include/openmpi/ *just in case* you use the openmpi variant of HDF5?

Seems to me that the best solution would be for macports to put mpi.h into opt/local/include directly (or soft link it), rather than in an openmpi subdirectory.

Any suggestions?
