[Serusers] Error when loading the MySQL module

Hi Everybody, I am a beginner here. Could anyone please answer my question? I have downloaded the SER-0.8.14 source code and compiled it on a Redhat Linux 9 box. It works perfectly. But after I added the MySQL module and run it again, the following error message is logged in the system log file: Jun 1 16:00:58 localhost ser: ERROR: load_module: could not open module </usr/local/lib/ser/modules/mysql.so>: libmysqlclient.so.14: cannot open shared object file: No such file or directory Jun 1 16:00:58 localhost ser: parse error (30,13-49): failed to load module And the shell window also display an error message: ERROR: bad config file (3 errors) I checked the mysql.so file, and it is there as the ser.cfg required. What might be the error here? Best regards, Juntong Liu
