Dear All,I'm experiencing the difficulties with running the Petsc in Fortran 
Language, I'm using gfortran integrated in the CodeBlock editor. I've 
compiled/installed the Petsc , Slepc and having noproblems calling the 
Petsc/Slepc functions in C, it works perfectly.
When it comes to using Petsc in Fortran I follow the instructions given in that 
article, especially the item 
3http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Sys/UsingFortran.html
but so far I couldn't succeed to run them succesfully in Fortran,  my main code 
is as follow:
program mainimplicit none#include <finclude/petscsys.h>#include 
<finclude/petscvec.h>#include <finclude/petscvec.h90>
PetscReal norm
print *,"Hello World "end
I've added all the related include folders to search path 
(Petsc_Dir\include\finclude etc..) and library file "libpetsc.a" which results 
after Petsc compilation, but still compiler complains about the "Error: 
Unclassifiable statement at (1)" PetscReal norm. Which means that compiler is 
unaware of type identifier PetscReal. What am I missing here ?
Your help will be appreciated,
Regards,
