compile problems with mysql - php4.3.1

Hi All; This is driving me crazy. I've been seaching the various newsgroups and forums for days and have found similar problems but no answers. I have been trying to install php 4.3.1 I am using Redhat 8 Apache 2.x with MySQL4.0.12. I have gotten the same error with Redhatt 7.3 apache 1.3.x and MySQL 3.23.56. I configure ./configure --with apxs2 --with-mysql --enable-track-vars The configure runs and make errors out with: ext/mysql/libmysql/my_tempnam.lo: In function `my_tempnam': /usr/local/php-4.3.1/ext/mysql/libmysql/my_tempnam.c:103: the use of tempnams dangerous, better use mkstemp' php4.2.x will compile So I try to tell it where mysql is and I'm not sure what it wants. /var/lib/mysql is where the data is, the mysqld is in /usr/sbin and the header file mysql.h is in /usr/include/mysql, the mysql client is in /usr/bin I've givin it all those directorys and configure still tells me it can't find the headers. So if someone could give me a hint about this I would appreciate it. Again this all worked fine with php4.2.x
