Hi, Im trying to put callweaver on a embeeded device with gsm support, and i've converted the gsm drivers, they compile but when they start i get a...
/usr/lib/callweaver/modules/chan_gsm.so: undefined symbol: cm_create
Thing is , the symbol is part of a res_configman included on the driver and
that loads fine.
Can please please please someone explain me how the symbol lookup works in
callweaver? How do i put the res_something symbols in the global symbol table ,
im a 0 in C. Im doing this by trial and error (mostly error)
Regards
Carlos Galveias
