Codeblocks on fedora 9 : Cannot build the C project

Question

I have a simple C console application named Test. But when I build, it says

  Test - Debug uses a invalid compiler 
    Nothing to do

What is the error? The test.cbp(project file) contents are as follows:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<CodeBlocks_project_file>
    <FileVersion major="1" minor="6" />
    <Project>

     <Option compiler="gcc" />
