Hi,<br>
<br>
I am writing a custom module called mod_aw for freeswitch that uses a dynamic library called aw.so containing a c++ class. I edited the makefile for my module to:<br>
<br>
BASE=../../../..<br>
LOCAL_LIBADD+=./lib/aw.so<br>
include $(BASE)/build/modmake.rules<br>
<br>
I am able to build the module and also modified modules.conf to include the new module.<br>
<br>
When I start freeswitch, I don't see a message that the module was loaded.<br>
<br>
When I type: reload mod_aw I receive the following error:<br>
<br>
2012-09-28 04:49:52.738493 [CRIT] switch_loadable_module.c:1310 Error Loading module /usr/local/freeswitch/mod/mod_aw.so<br>
**/usr/local/freeswitch/mod/mod_aw.so: undefined symbol: _ZN10CAWETalker9ConfigureEPKc**<br>
<br>
-ERR unloading module [No such module!]<br>
+OK Reloading XML<br>
-ERR loading module [module load file routine returned an error]<br>
<br>
I know the library works as I have tried it in another program outside of freeswitch. I am not sure what I am doing wrong. 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.<br>
<br>
Any help on how to configure this would be greatly appreciated.<br>
<br>
Thank you in advance.<br>
<br>
-Jon<br>
