I have compiled lam-7.0.6 using the options given in the VASP makefile and made mpif77 using pgf77. I have changed the VASP makefile for parallel version. In the mpi section of the makefile, it is written that after compiling lam, FC=mpif77 can be used. But when i try to compile VASP it is giving many syntax errors. Is it possible to compile VASP using 'mpif77' as given in the makefile. We have already compiled VASP serially using 'pgf90' on AMD Opteron and it is running well. Please help...

Hi,
you may cheat a little:
mpif77 normally only supplies the proper paths for libs and include files, so it's only necessary for linking. Try to compile with pure FC=pgf77 (or pgf90) and take mpif77 only for linking the objectfiles.
