how to install gtkmm on ubuntu 16.04 in 3 steps

To Install gtkmm on ubuntu 16.04 / 14.04 follow the 3 steps bellow.

•  step 1 : install the updates 

sudo apt-get update 

• step 2 :   Install the Gnu c++ compiler "g++" if is not installed (you will need it to compile your code ).

 sudo apt-get install g++

• step 3 : Install gtkmm  

 sudo apt-get install libgtkmm-3.0-dev 

Now after doing this 3 steps the installation is done you need now to create a simple application example and compile it to check if every thing is working .

you can copy past the example bellow to chack if your environment is ready to start programing with gtkmm 

• first step you need to create a c++ file like the example.

in our example the file name is GtkmmTutorial.cpp

 #include <gtkmm.h>

int main(int argc, char *argv[])
{
 
  Gtk::Main kit(argc, argv);
  Gtk::Window GtkmmTutorial;
  GtkmmTutorial.set_default_size(400, 400);
  Gtk::Main::run(GtkmmTutorial);

  return 0;
}

• second step compile your code you can replace "GtkmmTutorial.cpp" by your file name and the output file "GtkmmTutorial" by any name you want.

g++ GtkmmTutorial.cpp -o GtkmmTutorial `pkg-config gtkmm-3.0 --cflags --libs`

• last step after compiling your code  you will see a new executable file, just double click on it and you will see an empty window.
