[Freeswitch-users] building mod_opal and v1.2stable

I found this on the opal mailing list archive:


The "endpoint" files (local, IVR, PCSS etc) were moved to an ep
directory. It is not "one level higher".

So if you had #include <opal/localep.h> it is now #include <ep/localep.h>


So it looks like this is an actual change in the opal library and mod_opal
will need to be patched.

I've added that info to the Jira ticket
http://jira.freeswitch.org/browse/FS-5054.

I think that part may have been easy to overlook as the Jira title says it
builds ok and the header issue is buried within the description of the
instability problems. Possibly it should've had its own Jira separate to
the crash.
