When I have seen this problem before, it *usually* indicated a mismatch of Open MPI versions that were not ABI compatible. I.e., the application was compiled and linked against Open MPI version X, but then at run time, it found the shared libraries for Open MPI version Y -- and X is not ABI compatible with Y.
That being said: >> Warning: size of symbol `mpi_fortran_argv_null_' changed >> from 1 in foo.o to 8 in lib/libfoolib2.so Doesn't sound like a version mismatch problem. A quick check through the history of OMPI's source code reveals that mpi_fortran_argv_null has been a (char*) since way back in v1.2.x days. So I'm curious as to how it could have a size of 1. How did you compile foo.o? On Mar 27, 2011, at 5:41 PM, Dmitry N. Mikushin wrote: > I checked that this issue is not caused by using different compile > options for different libraries.
