compiling PHP - configure error
 

Hello,

I get the following error after going for --configure with --with-xpm:


So I thought to myself, "Installing the developer package is what you need" and did a smooth "sudo apt-get install libxpm-dev" - which surprisingly told me that libxpm-dev is already the newest version.

Does anyone know now how to go on? Googl'ing for the problem keeps be pinned down to the installing the libxpm-dev package.

More information:

- Running on Ubuntu 12.04 Server Edtion (within a VM established with Vagrant (-> www.vagrantup.com))
- Exact command used: ./configure [... more options ...] --with-xpm-dir
- I am root while executing any command

I think you could hack the location where configure is checking for the existence of that file by setting up an environment variable or --with-xpm-dir=
