I have also implemented int bssgp_prim_cb(struct
osmo_prim_hdr *oph, void
*ctx) { return -1; } to make compilation error go away, is this going to
mess up the lib?
Not for simtrace, but it will for some other application.
That also means that the -no-undefined patch can't be merged because
it would break compilation AFAICT.
Cheers,
Sylvain
