Well, set up a RH9 system the other day. Installed Apache 1.3.27, MySQL 4.0, and began to install php4.0. All fairly new to this, but everything seemed to be going alright.

ran ./configure --with-mysql=/usr --with-apxs=/usr/local/apache_1.3.27/bin/apxs in php's directory.
Ran the make file.
Upon executing make install I received the following:

make install

Not entirely sure what is going on here, but attempted to rpm -u a glibc rpm for RH9 but as it was already installed, so it didnt let me do that. Performed the ./configure line with a --without-pear and that worked. However, ./bin apachectl would not launch and gave me the same error!

Any help and explanation of how to fix/work around this would be appreciated.

RH9 is using glib 2.3.2 I started out with Apache 1.3, and i really havent noticed much of a change with Apache 2, and the PHP and MySQL (both the server and the php-mysql module) come with the distro. I would try these first.

Oh yeah..... there is a major difference between 2.0, 2.1, 2.2 and 2.3......just ask the wine people and they will tell ya all about it ;-).

For Redhat 9.0, It is a bug of PHP -- better use PHP 4.2RC2 or the last snapshot.
