[mpich2-dev] want to cross compile mpich2

[chan at mcs.anl.gov]

This is a cross-compile bug in mpich2 configure.

The temporary workaround is look upi MPI_OFFSET_TYPE in
<mpich2_build_dir>/src/mpi/romio/localdefs, and define
MPI_SIZEOF_OFFSET=sizeof($MPI_OFFSET_TYPE) as part of
configure command.  Setting MPI_SIZEOF_OFFSET in configure
will avoid the runtime test and so configure should run to
completion. 

Could you file a bug report at
https://trac.mcs.anl.gov/projects/mpich2/newticket ?
