Dear serusers, I have downloaded the ser-0.9.13 source code and compiled it on a FC4. It can be started succesfully WITHOUT mysql support and I can make phone alls. But when I add the mysql modules in ser.cfg and start ser, it shows the following error message: 0(20691) ERROR: load_module: could not open module </usr/local/lib/ser/modules/mysql.so>: /usr/local/lib/ser/modules/mysql.so: undefined symbol: ERR_get_error_line_data 0(20691) parse error (29,13-14): failed to load module ERROR: bad config file (1 errors) I checked the mysql.so file and the database and both are right. Can anyone give me a help? Thanks. Best Regards, iceboy
