intalling from source - error message: can't find X includes
 

Hi everybody,

as a newbie I tried to install some applications from source. I sucessfully installed krusader (great!) from rpm, now I tried kdiff3 0.9.90 and krename 3.0.12.
After ./configure ran a while, it aborted with this error:

checking for X... configure: error: Can't find X includes. Please check your installation and add the correct paths!

I ran into this error message before with another attempt from source and gave up. Now I'd like to know what went wrong.
I use Mandriva 2006.0 with KDE 3.5.4 and gcc 4.0.1.
Grateful for any clue.

The most common newbie error which would produce that error message is not having the development packages installed. In red hat they're called package-name-devel, so search for names like libx-something-devel. Debian has an xlibs-dev dummy package which depends on a lot of x library headers, maybe mandriva has something like it?
