I just checked out OpenMPI trunk (3 feb 2010) after continuing my
adventures from the 19th of January
(http://www.open-mpi.org/community/lists/users/2010/01/11810.php,
"Win32 compilation broken (MSVC2008, OpenMPI1.4.1)")
Every time I try to get even a simple mpi application to compile I get
linker errors (in this case about _ompi_mpi_double, _ompi_mpi_int and
_omp_mpi_comm_world being unresolved external symbols) even when
libmpi.lib and libmpi_cxx.lib are added as additional dependencies).
Hell, even the most simple:
#include <mpi.h>
#pragma comment(lib, "libmpi.lib")
int main(int argc, char* argv[]) {
int n = 0;
MPI_Comm_size(MPI_COMM_WORLD, &n);
return 0;
}
gives a linker error when using shared libraries about
_ompi_mpi_comm_world. The symbol is defined however in libmpi.lib, as
witnessed by dumpbin. /me is really confused now.
While looking through the code of openmpi I came across a few
interesting warnings, see below:
