[Freeswitch-dev] Linking C++ .so Into Custom Freeswitch Module

Thanks for your reply. The problem is that I'm not sure I'm linking the external libs correctly. My module makefile is:
Shouldn't LOCAL_LIBADD be enough. Or do I need additional statements in my makefile. The aw.so defines the symbol in question yet I still receive the missing symbol message when I try to load the module.
Any help would be greatly appreciated.
Thanks in advance.

I am wondering whether I need to provide extern "C" linkage for the c++ library. However, I only have the .h file and .so file for the library. Or, do I need to add something to my Makefile.
