[SR-Users] Compile with mysql error

Hello, We have a system which Kamailio fails to compile mysql support on, even though the library is installed. The mysql packages are: MySQL-client.x86_64 5.5.28-1.rhel5 installed MySQL-devel.x86_64 5.5.32-1.rhel5 installed MySQL-server.x86_64 5.5.28-1.rhel5 installed MySQL-shared-compat.x86_64 5.5.28-1.rhel5 installed The error from the Kamailio install is: /usr/bin/ld: cannot find -lmysqlclient collect2: ld returned 1 exit status make[1]: *** [db_mysql.so] Error 1 make: *** [install-modules] Error 1 make: Leaving directory `/usr/src/kamailio-3.3.2' Would anyone be able to advise please? Thanks in advance. -- David Cunningham, Voisonics http://voisonics.com/ USA: +1 213 221 1092 UK: +44 (0) 20 3298 1642 Australia: +61 (0) 2 8063 9019
