[sr-dev] Problem with app_mono module

[Pirjo Ahvenainen]

Hi,

Thanks Daniel, good to know! I got it working wonderfully on Ubuntu,
only one warning I got when starting Kamailio:

Mar 30 20:31:04 monotest kamailio: WARNING: <core> [sr_module.c:627]:
/usr/local/lib/kamailio/modules/app_mono.so: exports dlflags interface
is deprecated and it will not be supported in newer versions; consider
using mod_register() instead

The example I tried works nicely though. I can use Ubuntu for playing
with the mono stuff, thanks for the advice!

cheers,
Pirjo
