But just to confirm: you said that your pathscale compilers *do* compile 1.7.3 -- including the mpi_f08 module -- with no problems? That would be a little surprising, because those same >=32 character symbol names are in 1.7.3...
Not quite - I was a bit too quick in composing that email.
The mpi_f08 stuff is NOT getting built in 1.7.3 when using pathf95.
What I should have said is "the fortran code and configure script in 1.7.3 work together to produce a failure-free build".
$ bin/ompi_info | grep -e Ident -e Fort
Ident string: 1.7.3
Fort mpif.h: yes (all)
Fort use mpi: yes (full: ignore TKR)
Fort use mpi size: deprecated-ompi-info-value
Fort use mpi_f08: no
Fort mpi_f08 compliance: The mpi_f08 module was not built
Fort mpi_f08 subarrays: no
Fort compiler: pathf95
Fort compiler abs: /project/projectdirs/ftg/ekopath-18.104.22.168/bin/pathf95
