Error when compiling FB / GTK tuto sample

[Wawa]

Hello,

I try to compile the following code under linux (Kubuntu 12.10) :

Code: Select all

ZetCode FreeBASIC GTK tutorial
'
' This program centers a window on 
' the screen

#include once "gtk/gtk.bi"

#define NULL 0

Dim As GtkWidget Ptr win

gtk_init(NULL, NULL)

win = gtk_window_new(GTK_WINDOW_TOPLEVEL)
gtk_window_set_title(GTK_WINDOW(win), "Center")
gtk_widget_set_size_request(win, 250, 150)
gtk_window_set_position(GTK_WINDOW(win), GTK_WIN_POS_CENTER)

g_signal_connect(G_OBJECT(win), "destroy", _
    G_CALLBACK (@gtk_main_quit), NULL)

gtk_widget_show(win)
gtk_main()

END 0

This come from a FreeBasic - GTK tutorial : "http://zetcode.com/gui/fbgtk/".

When I compile I receive the following errors :
ld : ne peut trouver -lgtk-x11-2.0
ld : ne peut trouver -lgdk-x11-2.0

Any ideas on what I should do to get this code working ?

Many thanks for the help.

Hello Wawa, welcome at the forum!

I cant read French but I assume that the linker ld cannot find the two libraries. One reason may be that in Ubuntu 12.10 only GTK+-3.0 is installed by default and you have to install GTK-2.0 manually:

• sudo apt-get install libgtk2.0-dev

But you also can switch to the newer version by prepending

• #DEFINE __USE_GTK3__

befor the #INCLUDE ONCE "gtk/gtk.bi" statement in your code. (This DEFINE is allready prepared in the examples shipped with fbc-0.24.) Then you need to install the development package for GTK+3 by executing

• sudo apt-get install libgtk-3-dev
