Code::Blocks

I just installed Code::Blocks and when i press build and run nothing happens except it says
""Basic Calculator - Debug" uses an invalid compiler. Skipping...
Nothing to be done."
in the build log. Please Help.

Thank You.

Did you install the version that comes with MinGW, or just the IDE? There is one that comes with a compiler and one that doesn't. If you have the one that doesn't, you need to configure code::blocks to use whatever installation you have.

ok thank you
