I looked at Makefiles and can see instruction # WARNING: do not add mode=debug or mode=release anymore in the Makefile, # use make mode=debug all instead. By default Kamailio is compiled with # debugging symbols in all cases (-g) and without optimization (-O0). https://github.com/kamailio/kamailio/blob/master/src/Makefile.defs#L749-L751 <https://github.com/kamailio/kamailio/blob/master/src/Makefile.defs#L749-L751> I do not understand how properly build Kamailio with disabled optimization. Could you let me know how to use "mode=debug"?
