I want to set up an Apache Webserver for hosting multiple ssl domains. This is only possible with a recent version of this webserver: version 2.2.12 or later. Since I could not find any rpm packages for such a recent version I am trying to compile it myself, using the configure option

--enable-ssl

undefined reference to `apr_os_uuid_get'

So I went back to the apache installation instruction and found that the configure option

--with-included-apr

However no matter how often I tried, I kept getting this error message. I even tried using a manually installed APR using the options

--with-apr

--with-apr-util

It turned out that I needed to do a

make clean

make
