ubuntu - C++ CodeBlocks compile two source files -


i have tried compile files codeblocks have downloaded here:

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

when try compile code blocks error:

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

but compile terminal works:

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

is there idea how make code blocks compile 2 source files ? enter image description here

the command put in terminal looks different command codeblocks executing, fact different logic. in case of undefined reference means forgetting include somewhere. examplewindow declared/defined? in included in main through 1 of 2 includes doing?
