Subject: Re: [OMPI users] Undefined symbols with MPI_Get_address
From: Hugo Gagnon (opensource.openmpi_at_[hidden])

I could replicate the problem with the following:

program test
use mpi
integer :: ierr, a
integer(kind=MPI_ADDRESS_KIND) :: address
call MPI_Init(ierr)
a = 0
call MPI_Get_address(a,address,ierr)
write(*,*) address
call MPI_Finalize(ierr)
end program test

$ openmpif90 test.f90
Undefined symbols for architecture x86_64:
 "_mpi_get_address0di4_", referenced from:
     _MAIN__ in ccLLbLGQ.o
ld: symbol(s) not found for architecture x86_64
