[mpich-discuss] installation problem on AIX

[Eric Sun]

Dear MPICH2 developers and users,

I successfully installed mpich2-1.4.1p1 on an IBM Power5 SMP machine
running AIX system. The configure line was
./configure --prefix=/install/directory --with-device=ch3:nemesis

I had CC=xlc CXX=xlC F77=xlf FC=xlf90

"configure" and "make" are quite smooth without error. But when I try to
compile a testing MPI code (calculating Pi), I receive the following error
message:

** main   === End of Compilation 1 ===
1501-510  Compilation successful for file Pi.f90.
ld: 0711-317 ERROR: Undefined symbol: .mpi_init
ld: 0711-317 ERROR: Undefined symbol: .mpi_comm_rank

ld: 0711-317 ERROR: Undefined symbol: .mpi_recv
ld: 0711-317 ERROR: Undefined symbol: .mpi_finalize

Any suggestion?

Thanks!
