Install and configure Gtk and Qt compiling environments in Ubuntu

Install and configure Gtk and Qt compiling environments in Ubuntu (Ubuntu. the GCC already exists in the system where the basic development environment GCC has just been installed, but almost no GCC file can be compiled, because some necessary header files are missing, therefore, install the build-essential software package. You can search for build-essential in the new version or enter the following command: sudoapt-getinstallbuild-ess

Install and configure Gtk and Qt compiling environments in Ubuntu (the system environment is Ubuntu 12.04)

1. Configure the basic development environment GCC

GCC already exists in the newly installed system, but almost no GCC file can be compiled. Because some necessary header files are missing, you need to install the build-essential software package. You can search for build-essential in the new version or enter the following command:

Sudo apt-get install build-essential program example

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

Program example:

Hello. c

# Include
Int main ()
{
Printf ("Hello Ubuntu! ");
Return 0;
}

Compile and run:
$ Gcc testc. c-o testc
$./Testc

Output:
Hello Ubuntu!

2. Install the GTK/GNOME Development Environment
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-docs
Program example
After the installation is complete, we also make a test program (CodeLanguage: C, only 1 header file)

Hello-ubuntu_gnome.c

# Include
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 gtktest. c-o gtktest 'pkg-config -- cflags -- libs gtk +-1000'

$./Gtktest

// 'Pkg-config -- cflags -- libs gtk +-2.0 'Library Reference

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