mod_mosquitto cannot be loaded by FreeSWITCH

[ginkel]

Hello everyone,

while evaluation options to connect our FreeSWITCH instance to MQTT I came across mod_mosquitto. Unfortunately, I haven't been able to successfully load it into FreeSWITCH 1.10.10. Our FreeSWITCH deployment is using a Debian 11 based Docker image that installs FreeSWITCH using the official Debian packages. I temporarily published the Docker build at: https://github.com/tgbyte/docker-freeswitch.

I am using the following Makefile (based on https://developer.signalwire.com/freeswitch/FreeSWITCH-Explained/Community/Contributing-Code/Creating-New-Modules/#using-development-headers-libfreeswitch-dev) to build the module against libfreeswitch-dev instead of compiling FreeSWITCH from scratch: https://github.com/tgbyte/docker-freeswitch/blob/main/Makefile

Describe the bug
The built module cannot be loaded by FreeSWITCH (despite being present in /usr/lib/freeswitch/mod):

2023-11-13 22:10:38.469896 0.00% [CRIT] switch_loadable_module.c:1754 Error Loading module /usr/lib/freeswitch/mod/mod_mosquitto.so
**Module load routine returned an error**

Unfortunately, increasing FreeSWITCH's log level did not lead to more information. Executing ld on the module's .so does not show any dependency issues.

Any ideas?

Thanks,
Thilo

Sorry for the delay. Will look into this even though I expect that you've "moved on".

Thanks for getting back to me! I am currently using baresip to signal calls via mqtt, but getting this module to work would be really nice.

Let me know if you need any further details!
