C++ CodeBlocks compile two source files

I have tried to compile those files by CodeBlocks which i have downloaded from here:

https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/frame?h=master

When i try to compile it with Code Blocks i get that error:

main.cpp|8|undefined reference to `ExampleWindow::ExampleWindow()'|

But i compile it like that from terminal it works:

g++ main.cc examplewindow.cc -o simple `pkg-config gtkmm-3.0 --cflags --libs`

Is there any idea how to make Code Blocks compile two source files ? enter image description here

The command you put in your terminal looks completely different from the command codeblocks is executing, so the fact that it does something different is logic. However in the case of a undefined reference it usually means that you are forgetting an include somewhere. Where is ExampleWindow declared/defined? Is it in included in your main through one of the two includes you are doing?
