Can't compile sample GTK app
There seems to be something wrong with either GCC or with GTK. I recently tried to compile the sample GTK application in a programming book I got, but it will not compile. It complains about do_click being undeclared, though it should be declared in gtk.h.
I'd been able to compile GTK programs with the same function doing the exact same thing before, so I don't know what's wrong. Here's the program. #include <stdio.h> #include <gtk/gtk.h> #include <gdk/gdk.h> int main(int argc, char *argv[]){ GtkWidget *window, *button; int count = 0; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); //gtk_container_border_width(GTK_CONTAINER(window), 5); button = gtk_button_new_with_label("Click to increment counter"); gtk_signal_connect(GTK_OBJECT(button), "clicked", GTK_SIGNAL_FUNC(do_click), &count); gtk_container_add(GTK_CONTAINER(window), button); gtk_widget_show(button); gtk_widget_show(window); gtk_main(); return 0; } GCC 3.3.4 GTK +- 2.0 |
What is the entire error message?
|
14 Error: do_click undeclared (first use in this function)
14 Error: (Each undeclared identifier is declared only 14 Error: once for each function it appears in.) |
I don't find a do_click in my gtk.h and related files. Where did you find this sample?
|
The book is "Linux Programming 2nd edition UNLEASHED"
I see you may be right. I just looked at the tutorial on gtk.org and they did the same program differently. |
I wonder if that book may be thinking gtk-1.2? I haven't looked in those header files, just gtk2 since that is what you specified above.
