gtkmm 질문입니다.

우분투에서 gtkmm을 사용하기 위해서 libgtkmm-2.4-dev를 패키지로 설치하고

g++ base.cc -o base `pkg-config --cflags gtkmm-2.4 --libs gtkmm-2.4`

이렇게 컴파일을 했더니 아래처럼 에러가 나옵니다.

Package xdmcp was not found in the pkg-config search path.
Perhaps you should add the directory containing `xdmcp.pc'
to the PKG_CONFIG_PATH environment variable
Package 'xdmcp', required by 'X11', not found
base.cc:1:19: error: gtkmm.h: No such file or directory
base.cc: In function ‘int main(int, char**)’:
base.cc:4: error: ‘Gtk’ has not been declared
base.cc:4: error: ‘Main’ was not declared in this scope
base.cc:4: error: expected `;' before ‘kit’
base.cc:5: error: ‘Gtk’ has not been declared

base.cc:6: error: ‘Gtk’ has not been declared
base.cc:6: error: ‘window’ was not declared in this scope

gtkmm을 하는데 왜 xdmcp를 찾는거죠?
뭐가 문제인지 도무지 모르겠네요. 젠투에서는 별다른 설정도 없이 그냥 gtkmm깔고 바로 된다더군요. xdmcp같은건 필요도 없구..
혹시 우분투에서 gtkmm을 사용하고 계신 분이나 사용해 보신분 계시면 방법좀 알려주세요.

컴파일하려고한 파일은 gtkmm tutorial에 나와있는 기본 예제 파일입니다.

      1 #include <gtkmm.h>
      2
      3 int main(int argc, char *argv[]){
      4         Gtk::Main kit(argc, argv);
      5         Gtk::Window window;
      6         Gtk::Main::run(window);
      7         return 0;
      8 }
