Josh, The specific compilers that caused the most problems are the older PGI compilers (any before 13.x). In this case the user has the option to update their compiler to 13.10 or newer.
There are also issues with IBM's xlf. For the IBM compiler I have never found a version that builds/links the MPI f08 bindings, and now also find no version that can link the OSHMEM fortran bindings. -Paul -Paul On Thu, Aug 14, 2014 at 11:30 AM, Joshua Ladd <[email protected]> wrote: > We will update the README accordingly.
