[mpich-discuss] mpif90 and mpicc problems

[jcrosby]

Ohh, I see it now. I was running just mpif90/mpicc by themselves and
getting that error. I tested it on the f90 example in the example dir
and it made an a.out file which ran. So it did install correctly and
does work.

Reason I was asking was because I have a program I'm trying to compile
that uses bpif90 and mpicc. However that program returns errors while
compiling. I asked that user group and they told me that it mpich was
most likely the issue. But seeing as mpif90 and mpicc compiled the
example programs it must be something on the other end.

I'll give a snip of the error the program I'm trying to compile is
giving, maybe someones seen it with something else.

[Error]
solve_nmm.f90:(.text+0x518): undefined reference to `mpi_send_'
solve_nmm.f90:(.text+0x555): undefined reference to `mpi_barrier_'
solve_nmm.f90:(.text+0xc0e): undefined reference to `mpi_recv_'
[/Error]

Their code is giving me that but they keep telling me its my MPI install.
