You need to link with glib so you need something like '-lglib' (I guess that's 
its name) on the commandline. You can also enter it in the project settings 
of Kdevelop. Otherwise, this error has not too much to do with kdevelop but 
is rather a 'normal' C errror.

C (and C++) are slightly broken IMHO in that they require you to #include a 
header and further to link to the according library. You only did one thing 
and got linker errors because of that.
