Answer : I'm guessing you've installed Code::Blocks but not installed or set up GCC yet. I'm assuming you're on Windows, based on your comments about Visual Studio; if you're on a different platform, the steps for setting up GCC should be similar but not identical. First you'll need to download GCC. There are lots and lots of different builds; personally, I use the 64-bit build of TDM-GCC. The setup for this might be a bit more complex than you'd care for, so you can go for the 32-bit version or just grab a preconfigured Code::Blocks/TDM-GCC setup here. Once your setup is done, go ahead and launch Code::Blocks. You don't need to create a project or write any code yet; we're just here to set stuff up or double-check your setup, depending on how you opted to install GCC. Go into the Settings menu, then select Global compiler settings in the sidebar, and select the Toolchain executables tab. Make sure the Compiler's installation director...

Answer : I faced the same problem. I have fixed out by going to Setting -> Compiler -> Global Compiler Settings -> Toolchain Execuatables (tab) . There, click on Program Files and then rename C compiler to gcc.exe and C++ compiler to g++.exe . I know this is an old question but let me see if I can help. First of all, on the download page make sure you downloaded codeblocks-13.12mingw-setup.exe and NOT codeblocks-13.12-setup.exe. Of course the version numbers may change but pay attention to the name. Then after installing codeblocks, go to Settings->Compiler->Toolchain executables. From here, change the C compiler to gcc.exe and C++ compiler to g++.exe. Hope this helps anyone else going through this problem :-)
