mysqli -> mysql

Hi! I have a trouble with building MySQL and MySQLi support together with PHP... Basically my config says: ../configure --with-mysql=/usr --with-mysqli=/usr/bin/mysql_config (and other switches) but I get this: /usr/lib/mysql/libmysqlclient.a(libmysql.o)(.data+0x0): multiple definition of `net_buffer_length' /usr/lib/mysql/libmysqlclient.a(libmysql.o)(.data+0x0): first defined here /usr/lib/mysql/libmysqlclient.a(libmysql.o)(.data+0x4): multiple definition of `max_allowed_packet' /usr/lib/mysql/libmysqlclient.a(libmysql.o)(.data+0x4): first defined here and that for basically for each function.... Anyone knows, how to make the mysqli and mysql extension work together? Thanks. Stormy.
