httpd-devel

1. Installing httpd-devel on CentOS 4

Customer problem: "I need to install apxs in order to recompile PHP as an Apache module. apxs is part of httpd-devel, and when I run "yum install httpd-devel", I'm told "Error: Missing Dependency: apr-util = 0.9.4-21 is needed by package apr-util-devel". The current version of apr-util is 0.9.4-22.el4, and if I try to remove it to downgrade it (there is a 0.9.4-21 version available on yum as well) it will break lots of other software installed, including Apache."

Solution:

After a bit of searching around, I found the appropriate version of apr-util in a repository called fasttrack. http://lists.centos.org/pipermail/centos/2006-April/063242.html

I added /etc/yum.repos.d/CentOS-fastrack.repo and disabled it by default, then ran

yum --enablerepo=fasttrack install httpd-devel
