PHP 4.2.1 / Mysql

Hello, I just installed PHP 4.2.1. I am using a Redhat 7.3, installed as server with Apache. I went to setup a distributed IDS (SNORT/MySQL/PHP/ACID). My second problem is the connection with my MySQL DB. ./configure --with-mysql ./configure --with-mysql --with-gd=../gd-1.8.4 --enable-sockets --with-config-file-path=/etc/httpd/conf --enable-track-vars [root@localhost php-4.2.1]# ./configure --with-mysql | grep mysql checking for MySQL UNIX socket... /var/lib/mysql/mysql.sock fastgen.sh: creating ext/mysql/Makefile fastgen.sh: creating ext/mysql/libmysql/Makefile The compilation with mysql seems fine. But when I check my Web page (Acid) PHP ERROR: PHP build incomplete: the prerequisite MySQL support required to read the alert database was not built into PHP. Please recompile PHP with the necessary library (--with-mysql) What can I do ?
