Good morning,
I have been trying to compile PETSc with 64bit indices and revolve. It compiles
ok but gives out warnings of the kind:
{PETSCDIR PATH REMOVED}/src/ts/trajectory/impls/memory/trajmemory.c:1479:130:
warning: incompatible pointer types passing 'PetscInt *' (aka 'long long *') to
parameter of type 'int *' [-Wincompatible-pointer-types]
whattodo =
revolve_action(&tjsch->rctx->check,&tjsch->rctx->capo,&tjsch->rctx->fine,tjsch->rctx->snaps_in,&tjsch->rctx->info,&tjsch->rctx->where);
/* must return 1 or 3 or 4*/
^~~~~~~~~~~~~~~~~~~
{PETSCDIR PATH REMOVED}/lib/include/revolve_c.h:14:49: note: passing argument
to parameter here
int revolve_action(int*,int*,int*,int,int*,int*);
Is revolve incompatible with 64bit indices by design?
Yes, Revolve uses int32 only. But we can fix the warnings by downcasting. You
can check out this MR:

Thanks,
Hong (Mr.)
Best wishes,
