Hi FreeSWITCH Guru's. Apologies in advance for silly question - I've been coding Java for last 15 years, so the C is not coming naturally yet. Met some of you at ClueCon 2011 - had a great time - defeated Ken Rice at pool in the Lucky Strike - (OK I was lucky). We have a conferencing customer who is currently using JAIN SLEE and Radisys (Convedia) media servers. We are exploring the possibility of replacing all this with FS. They have a multi-tier account structure with provisionable preferences (e.g they can have different DTMF menu's and conference behaviour per account/subscription). So I have built a mod, which bridges our business logic with mod_conference. This is all working very well, and I love developing on FS compared to JAIN SLEE. So that's the background - here's the problem I'm having. I am trying to implement some JSON reporting, which we send over rabbit MQ, and am trying to use the cJSON api in switch_json directly from my mod. ( I have written a couple of mods [mod_rabbit_send and mod_rabbit_recv] which send and receive rabbit MQ events, and convert them to/from FS custom events. It uses a MPL library from rabbit.org. Will be happy to contribute them to the project if you want them. ). I include switch_json.h in my mod, and the cJSON stuff compiles and installs ok. But when I install the mod I get.. 2011-09-12 17:56:49.195659 [CRIT] switch_loadable_module.c:928 Error Loading module /usr/local/freeswitch/mod/mod_netdev.so **dlopen(/usr/local/freeswitch/mod/mod_netdev.so, 6): Symbol not found: _cJSON_AddItemToObject Referenced from: /usr/local/freeswitch/mod/mod_netdev.so I have tried all sorts of things in my makefile to get this linking - to no avail - I'm out of ideas. Any help will be greatly appreciated.
