unixODBC failure/bug? - sr-users

29 Apr 2016

Hi all,

I am trying to use the unixODBC module to connect to MariaDB as a first step and then to
test it to connect to MSSQL (please don't blame me on MSSQL...). I am using Kamailio
4.3.5 on CentOS7.2 fully patched. Here info about installed unixODBC:

[root@r5dev-KAM1 ~]# yum list installed | grep unix
unixODBC.x86_64                       2.3.1-11.el7                    @base
unixODBC-devel.x86_64            2.3.1-11.el7                    @base

Which leads me to my possible problem that I can't start Kamailio with db_unixodbc.so
because it is giving me this error:

r5dev-KAM1 /usr/local/kamailio/sbin/kamailio[16307]: ERROR: <core> [db.c:203]:
db_bind_mod(): Module db_unixODBC not found. Missing loadmodule?

Followed by errors from modules depending on the DBURL are failing as well. Here my
modules part:

...
#!define DBURL "unixODBC://root:<passw>@localhost/MARIADB"
...
# Module Path
mpath="/usr/local/kamailio/lib64/kamailio/modules/"

loadmodule "tls.so"
# ----- tls params -----
modparam("tls", "config",
"/usr/local/kamailio/etc/kamailio/tls.cfg")

#loadmodule "db_mysql.so"
loadmodule "db_unixodbc.so"
...

I doublechecked that the module was compiled and is present:

[root@r5dev-KAM1 ~]# ls -ll /usr/local/kamailio/lib64/kamailio/modules/ | grep unix
-rwxr-xr-x. 1 root root  184451 28. Apr 08:56 db_unixodbc.so

I tried to check the db.c and db_unixodbc.c but I am not familiar with the c-syntax.
I somehow suspect that the error is related to Linux case sensitivity if db.c is trying to
check if "unixODBC" is installed and then trying to match it with the
"db_unixodbc.so" but I'm am not sure.

Can someone please give further advice?
