Isaac McDonald commented on ASTERISK-27590:
-------------------------------------------

For clarification, I'm not having issues building res_corosync. The module builds fine, it merely won't load. Have you verified the module actually loads after you're compiled it?

> Something changed after Asterisk 13.17.1 that broke res_corosync. I've installed the latest version 13.19.0 and corosync is still broken. This is especially frustrating seeing as how the corosync module was recently fixed after being broke for 2 years only to be broken again after a couple builds.

> 	* res_corosync: Fix linking issue with Corosync 2.x
> 	  At some point in time in the history of Corosync (certainly within the
> 	  2.x branch), the corosync_cfg_state_track function was removed.
> 	  Unfortunately, the cfg library is only linked if this function is
> 	  present. Without the cfg library being linked to res_corosync, loading
> 	  of res_corosync will fail.
> 	  This patch makes it so that detecting corosync's core libraries,
> 	  determined by the COROSYNC external library checks, links both the cpg
> 	  and cfg libraries with res_corosync.

> Here's the error that's produced in the log when trying to load the module:
> {noformat}
> loader.c: Error loading module 'res_corosync.so': /usr/lib/asterisk/modules/res_corosync.so: undefined symbol: corosync_cfg_fd_get
> {noformat}
> Here is the ticket for the corosync module that was resolved several months ago along with the patches and other info if it helps.
