Error Installing K3B. Need Explanation
 

I'm trying to install k3b-0.7.3 on Mandy 9.0 from the terminal. When trying to configure i got the following message.

[root@diebenkorn k3b-0.7.3]# ./configure --prefix=/opt/k3b/
.

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

What path must i correct? I have no idea what are X includes. Is it a compiler issue.

Appreciate any help! Thanks in advance

You are missing the X11 headers. So install the devel package for X.
