Hello everyone,

i'm trying to integrate petsc code into one big software. petsc would act as a solver for the program.
The way that i try to integrate my petsc code is like that:

########################

program myoldnonpetsccode

use mymodule

implicit none

call process_petsc

end myoldnonpetsccode
########################
module mymodule
implicit none


#include "finclude/petsc.h"

contains
subroutine process_petsc
call PetscInitialize(PETSC_NULL_CHARACTER,ierr)

call PetscFinalize(ierr)

end subroutine process_petsc
end module mymodule

###############


The compiler used for petsc, mpich and the non-petsc code is the same (PGI). I'm perfectly making my module file (.mod) for mymodule and object one (.o). This one is inserted into a library file (libtest.a).

When i try to make my binary "myoldnonpetsccode" my compiler tells me during the linking process that there's two undefined reference for 'petscinitialize_' and 'petscfinalize_'. I verified that petsc libraries where included during linking process (with -L/mypathtopetsclib and -lpetsc).

I don't find any answer to this on the internet and documentation.

Do you have any clue on what would be the problem ?

Thanks a lot

Best regards

PYA
