gtk_init()意外失败

我使用树莓派与GTK+,意思是ARM+Debian+GTK+。但即使是GTK网站的例子在我的环境中也总是失败。比如:

#include <gtk/gtk.h>

int main( int   argc,
      char *argv[] )
{
GtkWidget *window;

//gtk_init (&argc, &argv);
gtk_init_check(&argc, &argv);

window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_show  (window);

gtk_main ();

return(0);
}

我用汇编的

gcc -g gtktest.cpp -o base `pkg-config gtk+-2.0 --cflags --libs` 

并取得了成功。运行时,我得到了:

(base:12760): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(base:12760): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed

(base:12760): Gdk-CRITICAL **: IA__gdk_window_new: assertion `GDK_IS_WINDOW (parent)' failed
Segmentation fault

仅使用gtk_init()也会导致错误。 我检查了DISPLAY变量,并尝试将其设置为<我的IP>:0.0,但没有效果。我怀疑这可能是GTK无法获得显示资源的问题,但我没有找到解决这个问题的方法。

仅供参考,我正在使用腻子SSH到raspberryPi。
