1. Configuration
Gcc

Just installed system
GCC already exists, but no GCC file can be compiled, because there are no necessary header files, so install
Build-essential
Package, Installation
This package will be automatically installed
On G, libc6-dev, Linux-libc-Dev, libstdc 6-4.1-dev and some other necessary software
And header file library.

You can search for build-essential in the new version or enter the following command.
:

Sudo
Apt-Get install build-essential

After the installation is complete, write a C language program testc. C to test it.

Int main ()
{
Printf ("Hello Ubuntu
! /N ");
Return 0;
}

$ GCC testc. C-o testc
$./Testc

Hello Ubuntu!

2. Install GTK

Method1: to install the GTK environment, you only need to install libgtk2.0-Dev. to install the gnome development environment, you need to install gnome-core-
Devel, which contains the GTK development kit. But in general, we need an IDE development environment and a help file, so we install sudo apt-Get
Install gnome-devel gnome-Dev-Doc

----------------------------------------------------------------------
Method2:

Sudo apt-Get install gnome-core-devel # This will install libgtk2.0-dev libglib2.0-Dev and other development
Related library files

Sudo apt-Get install PKG-config # used to automatically find the header file and library file location when compiling the GTK Program

Sudo apt-Get install devhelp # This will install the devhelp GTK document
View programs

Sudo apt-Get install libglib2.0-Doc libgtk2.0-doc # This will install the GTK/glib api reference manual and other help documents

Sudo apt-Get instal Glade libglade2-dev # This will install the GTK-based interface constructor.

After the installation is complete, we also make a test program.

# Include <GTK/GTK. h>
Void Hello (gtkwidget * widget, gpointer data)
{
G_print ("Hello Ubuntu! /N ");
}
Gint delete_event (gtkwidget * widget, gdkevent * event, gpointer data)
{
G_print ("delete event occurred
/N ");
Return (true );
}
Void destroy (gtkwidget * widget, gpointer data)
{
Gtk_main_quit ();
}
Int main (INT argc, char * argv [])
{
Gtkwidget * window;
Gtkwidget * button;
Gtk_init (& argc, & argv );
Window = gtk_window_new (gtk_window_toplevel );
Gtk_signal_connect (gtk_object (window), "delete_event", gtk_signal_func (delete_event), null );
Gtk_signal_connect (gtk_object (window), "Destroy", gtk_signal_func (destroy), null );
Gtk_container_set_border_width (gtk_container (window), 10 );
Button = gtk_button_new_with_label ("Hello Ubuntu! ");
Gtk_signal_connect (gtk_object (button), "clicked", gtk_signal_func (Hello), null );
Gtk_signal_connect_object (gtk_object (button), "clicked", gtk_signal_func (gtk_widget_destroy), gtk_object (window ));
Gtk_container_add (gtk_container (window), button );
Gtk_widget_show (button );
Gtk_widget_show (window);/* display a window */
Gtk_main ();/* enter the main loop */
Return (0 );
}

Compile and run the following command:

$ GCC gtkhello. C-o gtktest 'pkg-config -- cflag
S -- libs GTK +-2.0'
$./Gtktest

A window with a button is displayed. click the button to close the window. The command line displays Hello ubuntu.
