If you are using the downloaded Windows version of Maratis, you will need Microsoft Visual Studio to build a game plugin (dll), there is a free version of it : http://forum.maratis3d.com/viewtopic.php?id=90
> The game plugin examples for Maratis are including a visual project file, so you can open the project and compile without anything complex to do.
I know you can also call the Visual Studio compiler from Code::Block, but I never tried it.
Do you only want to use the Maratis Engine ? Do you know you can create plugins to add additional c++ code while using the editor ?
There is a tutorial explaining how to create a plugin :
