Freddy, Thanks for the reply! I did what you have asked me to do. But still same problem. One question I got is: Does the version of mysql lib and include directory specified need to be same as the runing version. I means if I had a runing binary mysql, to make gnugk compile with mysql support. Can I just download the source code of a mysql package, and compile it with gnugk? Even it can compiled successfully, will it cause trouble due to uncompatibility problem? To make gnugk complie with mysql support , what exactly files does gnugk need, except mysql.h?
