[petsc-users] problem with PetscInitialize when moving to 3.19.0

[Danny Lathouwers - TNW]

Dear community,

I am transitioning a working Fortran code based on version 3.10.4 to version 3.19.0.
The code compiles except for one problem during linking where PetscInitialize can no longer be found (undefined reference to `petscinitialize_’).

I am attaching the piece of code where the call is made. Removing the call makes the whole code compile so this is the only error.
I added the include line of petsc.h as the documentation seems to imply this, but this did not help.

Any help is appreciated.

Thanks,
Danny.
