KDevelop newbie needs help...
 

I want to use KDevelop for a pre-written c code and its header. Before that I wanted to see if it works with a simple c code. I opened a new project file and write the simple c code. But the Build tools doesnt work,even the compiler compiles without an error.I couldnt figure out to generate the project.What is to be done more than writing the code,comiling and pressing build buttons?

The file with C code must be added to the project (you have such option when you create new file in KDevelop). Then you need to run autoconf/automake (somewhere in the Build menu, depending on the KDevelop version you're using). You're starting a new projekct in the Project menu (Project->New).

All above for KDevelop 3.0. Which version are you using?
