Nope, no luck. My environment is: OpenMPI 1.6.5 gcc 4.8.1 Mac OS 10.8
I found a ticket reporting a similar problem on OS X: https://svn.open-mpi.org/trac/ompi/ticket/1982 It said to make sure $prefix/share/ompi/mpif90-wrapper-data.txt had the following line: compiler_flags=-Wl,-commons,use_dylibs I checked mine and it does (I even tried to include it explicitly on the command line but without success), what should I do next? -- Hugo Gagnon On Sat, Sep 7, 2013, at 0:39, Tom Rosmond wrote: > Just as an experiment, try replacing > > use mpi > > with > > include 'mpif.h' > > If that fixes the problem, you can confront the OpenMPI experts > > T.
