Hi Sonya,

As this is Fortran 90, I think you should be using the double colon to allocate variables:

PetscReal :: norm

What it's got anything to do with PGI compiler I'm using Gnu Fortran?
I try to compile program with the given command lines executions.

-------------- Build: Debug in Petsc_Fortran (compiler: GNU GFortran Compiler)---------------

gfortran.exe -Wall  -g  -Wall   -IC:\Users\....\Downloads\petsc-3.3-p6\include\finclude -IC:\Users\...\Downloads\petsc-3.3-p6\arch-mswin-c-debug\include  -c D:\....\PROJECTS\CBFortran\Petsc_Fortran\main.f90 -o obj\Debug\main.o

I've tried with every possible fortran file extension, I'm sure that file is being 
pre-processed because if I comment the line of "PetscReal norm" it compiles and runs 
normally and produces the print statement on console screen.
