hi
I'm having trouble compiling a PETSc Fortran program, which uses a
Fortran module in a separate file, which itself uses PETSc.
Here's a fairly minimal example of the problem.
Main program test.F90:
---
program test
use my_module
implicit none
#include <finclude/petsc.h90>
PetscInt :: bar = 2
print *, 'foo = ', foo, 'bar = ', bar
end program test
---
Module my_module.F90:
---
module my_module
implicit none
#include <finclude/petsc.h90>
PetscInt:: foo = 1
end module my_module
---
my_module.F90 will compile OK but when I compile test.F90 I get all
kinds of errors like:
Error: Symbol 'mpi_file_null' at (1) conflicts with symbol from module
'my_module'
presumably because I've included petsc.h90 twice. But if I don't have
the include in both the module and the main program, I don't have access
to PetscInt in both.
How does one get around this problem? I couldn't find any example
problems using Fortran modules.
