Hi, I'm trying to execute the code example (about GTK and threads) at http://developer.gimp.org/api/2.0/gdk/gdk-Threads.html But whenever I execute it , it gives segmentation fault inside "gtk_init(&argc,&argv)" function. I have to mention that when I comment "g_thread_init" line, it works properly. What will be the problem? Is it my makefile: all : gcc -g -o gtkThread gtk-thread.c -lpthread `pkg-config gtk+-2.0 gthread --cflags --libs` Thanks in advance, Polat <code> /*------------------------------------------------------------------------- * Filename: gtk-thread.c * Version: 0.99.1 * Copyright: Copyright (C) 1999, Erik Mouw * Author: Erik Mouw <J.A.K.Mouwits.tudelft.nl> * Description: GTK threads example. * Created at: Sun Oct 17 21:27:09 1999 * Modified by: Erik Mouw <J.A.K.Mouwits.tudelft.nl> * Modified at: Sun Oct 24 17:21:41 1999 *-----------------------------------------------------------------------*/ /* * Compile with: * * cc -o gtk-thread gtk-thread.c `gtk-config --cflags --libs gthread` * * Thanks to Sebastian Wilhelmi and Owen Taylor for pointing out some * bugs. * */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <time.h> #include <gtk/gtk.h> #include <glib.h> #include <pthread.h> #define YES_IT_IS (1) #define NO_IT_IS_NOT (0) typedef struct { GtkWidget *label; int what; } yes_or_no_args; G_LOCK_DEFINE_STATIC (yes_or_no); static volatile int yes_or_no = YES_IT_IS; void destroy (GtkWidget *widget, gpointer data) { gtk_main_quit (); } void *argument_thread (void *args) { yes_or_no_args *data = (yes_or_no_args *)args; gboolean say_something; for (;;) { /* sleep a while */ sleep(rand() / (RAND_MAX / 3) + 1); /* lock the yes_or_no_variable */ G_LOCK(yes_or_no); /* do we have to say something? */ say_something = (yes_or_no != data->what); if(say_something) { /* set the variable */ yes_or_no = data->what; } /* Unlock the yes_or_no variable */ G_UNLOCK (yes_or_no); if (say_something) { /* get GTK thread lock */ gdk_threads_enter (); /* set label text */ if(data->what == YES_IT_IS) gtk_label_set_text (GTK_LABEL (data->label), "O yes, it is!"); else gtk_label_set_text (GTK_LABEL (data->label), "O no, it isn't!"); /* release GTK thread lock */ gdk_threads_leave (); } } return NULL; } int main (int argc, char *argv[]) { GtkWidget *window; GtkWidget *label; yes_or_no_args yes_args, no_args; pthread_t no_tid, yes_tid; /* init threads */ g_thread_init (NULL); gdk_threads_init (); gdk_threads_enter (); /* init gtk */ gtk_init(&argc, &argv); /* init random number generator */ srand ((unsigned int) time (NULL)); /* create a window */ window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_signal_connect (GTK_OBJECT (window), "destroy", GTK_SIGNAL_FUNC (destroy), NULL); gtk_container_set_border_width (GTK_CONTAINER (window), 10); /* create a label */ label = gtk_label_new ("And now for something completely different ..."); gtk_container_add (GTK_CONTAINER (window), label); /* show everything */ gtk_widget_show (label); gtk_widget_show (window); /* create the threads */ yes_args.label = label; yes_args.what = YES_IT_IS; pthread_create (&yes_tid, NULL, argument_thread, &yes_args); no_args.label = label; no_args.what = NO_IT_IS_NOT; pthread_create (&no_tid, NULL, argument_thread, &no_args); /* enter the GTK main loop */ gtk_main (); gdk_threads_leave (); return 0; } <code> _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
