[mpich-discuss] Compiled applications working standalone, but not using mpiexec

[Jayesh Krishna]

Hi,
 Please follow the steps below and let us know the results,

# Rename c:\Program Files\MPICH2\lib\libfmpich2g.a to c:\Program Files\MPICH2\lib\libmpifmpich2g.a
# Re-compile your code as follows,

  gfortran -o fpi fpi.f -lmpifmpich2g -lmpi

# Re-run fpi with/without mpiexec and let us know the results.

Regards,
Jayesh

Hello,
-localonly option has no effect - no output is produced.

I am able to compile and run successfully the icpi.c example, however, 
which leads me to believe the problem is related to compiling fortran 
code specifically.

I'm running MinGW, using GNU Fortran version 4.6.1. To compile fpi.f, I 
execute the following command:
gfortran -o fpi fpi.f -lfmpich2g

Which successfully compiles the program. I've read that there is an 
issue using the windows installer and fortran, since the libraries are 
compiled with the intel fortran compiler - is this correct?
