If I use gc_start(0), everything starts fine. If I start with gc_start(gc_start_struct) with the names of the libs to start, it fails.
I get: error: 0x124, Call control library not found.
I've tried everything, I can't see any mistakes, names are correct... (using GC_H3R_LIB and GC_IPM_LIB)
What can it be? (working on it for days now)
