1. Configure GCC
Just installed GCC can not compile anything, because there are no necessary header files, so to install build-essential, installed this package will install g ++, libc6-dev, linux-libc-dev, libstdc ++ 6-4.1-dev and many other necessary software and header files.
Sudo apt-get install build-essential
After the installation is complete, write a c language program testc. c to test it.
# Include
Int main ()
{
Printf ("Hello Ubuntu! \ N ");
Return 0;
}
$ Gcc testc. c-o testc
$./Testc
Display
Hello Ubuntu!
C language compiler installed successfully;
2. Install the GTK Environment
To install the GTK environment, you only need to install a gnome-core-devel, which integrates many other packages. In addition, some other things need to be transferred, such as libglib2.0-doc, libgtk2.0-doc help document, devhelp help document view, glade-gnome, glade-common, and glade-doc graphic interface design.
Sudo apt-get install gnome-core-devel
Sudo apt-get install libglib2.0-doc libgtk2.0-doc
Sudo apt-get install devhelp
Sudo apt-get install glade-gnome glade-common glade-doc
After the installation is complete, we also make a test program.
# 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 gtkhello. c-o gtktest 'pkg-config -- cflags -- libs gtk +-1000'
$./Gtktest
A window with a button is displayed. click the button to close the window. The command line displays Hello Ubuntu!
3 QT
Qt I installed
Libqt4-core
Qt4-designer
Qt4-dev-tools
Qt4-qtconfig
Libqt4-dev
Libqt4-gui libqt4-debug
Libqt4-sql
I have not used this yet. I searched QT4 in the new version and installed it almost.
5. install an IDE
In Linux, there is a C ++ IDE named Geany. In the menu "application"> "add and delete programs", find it in program.
