Error compiling PHP with native MySql

When I try to configure PHP 4.1.1 I get the following error: checking whether to include ming support... no checking for mnoGoSearch support... yes checking for mnoGoSearch version... 3.1.19 checking for mSQL support... no checking for Muscat support... no checking for MySQL support... yes configure: error: Cannot find header files under /usr/include/mysql The command line I'm using to configure: ./configure --with-mysql=/usr/include/mysql --with-java=/usr/java/j2sdk1.4.0 --w ith-xml --enable-shared-pdflib --enable-track-vars --with-db --with-gdbm --w ith- gd --enable-ftp --disable-debug --enable-memory-limit=yes --enable-trans-sid --w ith-apxs=/usr/local/apache/bin/apxs --with-mnogosearch=/usr/local/mnogosearc h I am on RedHat 7.1 with the following MySql RPMs installed: MySQL-devel-3.23.49-1 MySQL-client-3.23.49-1 MySQL-3.23.49-1 To check where the RPM installed the MySQL header files, I looked and found that they are in /usr/include/mysql [root@centauri local]# find / -name mysql -print /home/rfox/download/mnogosearch-3.1.19/create/mysql /usr/share/mysql /usr/bin/mysql /usr/lib/mysql /usr/include/mysql /usr/download/php-4.1.1/ext/mysql /usr/download/php-4.1.1/pear/DB/tests/mysql /var/lib/mysql /var/lib/mysql/mysql /var/lib/mysql-/mysql /var/lock/subsys/mysql /etc/rc.d/init.d/mysql /etc/logrotate.d/mysql So, I do not understand this error at all! Can anyone help? Thanks Rich
