After or while compiling some apps I get the following error message. Anyone have any ideas on what I should do? I am using redhat 6.2, installed 2 times. Does the same thing while trying to install an app for gnome as well. Here is the error. checking for kde headers installed... yes checking for kde libraries installed... configure: error: your system fails at linking a small KDE application! Check, if your compilier is installed correctly and if you have used the same compilier Qt and kdelibs as you did now thanks mickey
