This is just a short post to document the error I have encountered when trying to compile the libxml2 package on one of my CentOS 5 Linux servers. So here it goes, when I tried to configure the libxml2 package it returned the error below.

configure: error: cannot find macro directory `m4'

The configure script trying to find a non-existent directory named m4 — a Unix macro processor. Now, to fix the problem all you need to do is create the m4 directory , then run the configure script again and everything should be fine already.

That’s about it, very short eh!?
