gtkmm errors when compiling

 
0
 

I am new to c++ and to using graphics libraries, so please forgive me if I have made a silly mistake.

I am trying to compile a program that creates a window with one button from an example I found online. This is the error I get when I try to run my make file:

 sarah@superawesome:~/gtkexample$ make
 g++ -c main.cc
 In file included from HelloSarah.h:4:0,
                  from main.cc:1:
 /usr/include/gtkmm-3.0/gtkmm/button.h:7:28: fatal error: glibmm/ustring.h: No such file or directory
 compilation terminated.
 make: *** [main.o] Error

I have installed gtkmm, I can compile and run a single file no problem. I think my issue might be that I didn't install buttons? or that my make file is WAY off. I would really appreciate someone pointing me in the right direction. I have been searching online, but I really don't understand what I'm doing. I was however able to locate this file on my computer: /usr/include/gtkmm-3.0/gtkmm/button.h

Here is my Makefile and my 3 other files:

Makefile:

app:        main.o HelloSarah.o
        g++ -o app main.o HelloSarah.o

main.o:     main.cc HelloSarah.h
        g++ -c main.cc

HelloSarah.o:   HelloSarah.cc HelloSarah.h
        g++ -c HelloSarah.cc

clean:      
        rm -f *.o app

main.cc:

#include "HelloSarah.h"
#include <gtkmm/application.h>

int main (int argc, char *argv[])
{
  Glib::RefPtr<Gtk::Application> app = Gtk::Application::create(argc, argv, "org.gtkmm.example");

  HelloSarah hellosarah;

  //Shows the window and returns when it is closed.
  return app->run(hellosarah);
}

HelloSarah.cc:

#include "HelloSarah.h"
#include <iostream>

HelloSarah::HelloSarah()
: m_button("Hello Sarah")   // creates a new button with label "HelloSarah".
{
  // Sets the border width of the window.
  set_border_width(10);

  // When the button receives the "clicked" signal, it will call the
  // on_button_clicked() method defined below.
  m_button.signal_clicked().connect(sigc::mem_fun(*this,
              &HelloSarah::on_button_clicked));

  // This packs the button into the Window (a container).
  add(m_button);

  // The final step is to display this newly created widget...
  m_button.show();
}

HelloSarah::~HelloSarah()
{
}

void HelloSarah::on_button_clicked()
{
  std::cout << "Hello World" << std::endl;
}

and HelloSarah.h:

#ifndef GTKMM_HELLOSARAH_H
#define GTKMM_HELLOSARAH_H

#include <gtkmm-3.0/gtkmm/button.h>
#include <gtkmm/window.h>

class HelloSarah : public Gtk::Window
{

public:
  HelloSarah();
  virtual ~HelloSarah();

protected:
  //Signal handlers:
  void on_button_clicked();

  //Member widgets:
  Gtk::Button m_button;
};

#endif

I am not certain about this but the first thing I would try is for example

include <./gtkmm/window.h>

or

include "gtkmm/window.h"

Thanks for the reply, I just found my error. My makefile was WAY off.
