Thanks Jeff, and Davide,
I actually sucessfully compiled everthing with passing the FFLAGS to LAM
configure/build, although I have not run the application yet.
Do you mean even if it compiles, don't do the -f thing?
I think after I took out the FFLAGS from both, the undefined errors are
MPI unrelated, but I don't see any other libriaries being used. I am not
actually a programmer, it's other people's software. So I don't know too
much about the program. Could it be the '-f' is in his code, and has to be
there?
Regards,
Chen
