fortran compiler

kareempj · 03-28-2012, 09:53 AM

Hey how ya'll doing? I have a problem with compiling fortran code on my system, each time i try to compile it says:

Error: Can't open included file 'mpif.h'

Anyone have any ideas how to fix this problem?

Thanks in advance!

Software packages, that provide mpif.h, examples :

mpich-devel, libmpich1-devel, libmpich2-devel, libopenmpi-devel, openmpi-devel
libopenmpi-dev, libmpich2-dev, libmpich1.0-dev.

Different Linux OS's : Different package names.
And some programs require a specific version of "mpich".

Basically your system misses the Message Passing Interface (MPI) development files to compile and run parallel applications. A free implementation on Linux is openmpi, but depending on what Fortran compiler you're using you may want to install a proper MPI library. If you use gfortran maybe you simply need to install openmpi and openmpi-devel (this one providing the included file mpif.h, but the exact package name depends on your Linux distribution.

Thank you for your replies......The thing is I have those packages installed, the fortran compiler was previously working but for some reason it began giving that message recently...I'm working on a parallel machine using MPI, c++ code compiles and runs properly but only the fortran code seems to be giving problems!
