Bonjour Jacques!
(Hi Jacques!)
Now things are starting to make sense…
Can you do
yum install asterisk13-odbc
(if you are running Asterisk 13)
or
yum install asterisk14-odbc
(if you are running Asterisk 14)
and post the results back?
Do you get any error message, warnings about missing depencies, etc…?
If it installs properly, can you retry reloading the module (it might require a reboot but I don’t think so, at least to try to load it).
Good luck and have a nice day!
Nick
