Set up gtkmm-3.0 in Code::Blocks on linux for C++ GUI appz

I'm a beginning C++ programmer and want to use Code::Blocks IDE on Debian based Linux to write some GUI programs.

Therefore I would like to use gtkmm 3.0 with this code:

#include <gtkmm/gtkmm.h>
int main(int argc, char *argv[])
{
  auto app = Gtk::Application::create(argc, argv, "org.gtkmm.examples.base");
  Gtk::Window window;
  window.set_default_size(200, 200);
  return app->run(window);
}

The compiler gives me this error:

fatal error: gtkmm/gtkmm.h: No such file or directory

I followed these steps to install gtkmm:

  1. Installed Code::Blocks and was able to compile non-GUI programs.

  2. Then installed gtkmm-3.0 with synaptic.

  3. In Code::Blocks settings > compiler > compiler settings > other compiler options I set:

    pkg-config --cflags gtk+-3.0

  4. In codeblock settings > compiler> linker settings > other linker settings I set:

    pkg-config --libs gtk+-3.0

  5. When compiling I got the next error in Build log: 

    Build file: "no target" in "no project" (compiler: unknown)

I use a single .cpp file, not a Gtk+ project.

I've tried this and this but no luck. Does anyone know how to set up Code::Blocks and its compiler properly for gtkmm?

You've asked the IDE to search include directories for the GTK+ package with the command:

`pkg-config --cflags gtk+-3.0`

However, your program uses gtkmm, which is a layer on top of GTK+. You want to broaden the search to encompass the directories for gtkmm:

`pkg-config --cflags gtkmm-3.0`

(This replaces the current entry in the "other compiler options".) Similarly, you'll need to change, under "other linker settings", the library paths to:

`pkg-config --libs gtkmm-3.0`
