petsc version installed on machine is petsc-3.2-p5 I use a single include file: #include "finclude/petscdef.h" in the module and in the subroutines (including the ones that are defined after contains in the module) and program. #include "finclude/petsc.h" you can use #include "finclude/petsc.h90" if you are using the things such as vecgetArrayF90 On Tue, Aug 28, 2012 at 3:45 PM, Roc Wang <pengxwang at hotmail.com> wrote: > Hello, > > > I am developing Fortran90 code with PETSc.
