[SR-Users] Failure to load module db_mysql.so due to undefined symbol: log

[Pratab Ali]

Hello,

As per your suggestion, and following the dokuwiki page, I successfully
obtained kamailio using git and rebuilt and installed.
But unfortunately I get the same issue, when I execute kamailio using my
kamailio script.

Comparing the kamailio files in the GIT download to the ones I already
had, I found that they were identical barr the generated object files.

Please make any other suggestions before I decide to go to Debian?

Thanks
Pratab.

Hello,

should not be a problem to compile and run on opensuse. Can you pull
latest git branch kamailio_3.0 and try again? Hints at:
http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.0.x-from-gi
t

There were some files missing the logging include, hope will solve it --
on debian it was not reported so far. Let me know if works now on
opensuse.

Thanks,
Daniel
