It appears that setting module versions is the problem. If I append the
version number to mol_interface symbol (mol_interface_Rb923c717 for me) in
the get_module_symbols call in init.c then the code does return a pointer
to the molif struct. It also gets significantly further before failing
with unresolved symbols for Hash, Hash_mark, handle_mm_fault
next_mmu_context and last_task_used_math.
How should module version numbers be handled in the code. This is an area
I'm not very familar with. I can poke around some of the other module
code (usb, etc) to see how they do it but if someone has a quick answer
for me, that'd be better (smile).
