Hello again, I have to be more specific with my problem. 1) I am using the Mac OS X (Leopard) operating system. When I do uname -a, I get Darwin Kernel Version 9.5.0
2) My code if fortran 90 3) I tried using the mpif90 wrapper and I got the following message xxxxxxxxxxxxx mpif90 -c -O3 /Users/lamptey/projectb/src/blag_real_burnmpi.f90 -------------------------------------------------------------------------- Unfortunately, this installation of Open MPI was not compiled with Fortran 90 support. As such, the mpif90 compiler is non-functional. -------------------------------------------------------------------------- make: *** [blag_real_burnmpi.o] Error 1 xxxxxxxxxxxxx 4) I have the g95 compiler installed. So when I try using the g95, (with include "mpif.h" or 'mpif.h'), I get the following mesage: xxxxxxxxxxxxxx g95 -fno-pic -c -O3 /Users/lamptey/projectb/src/blag_real_burnmpi.f90 Error: Can't open included file 'mpif.h' make: *** [blag_real_burnmpi.o] Error 1 xxxxxxxxxxxxxxx 5) What are people's experience in this case?
