Hi all,
I have a application that was build using the gtk-1.2 readhat 9.0. The
application has two threads. The main thread is the display thread, while the
second one updates the display on sometimes.
When the secons thread updated the display , The following error occurs:
---------------------------------
Thread2:
update_alarm_report_window() <- function called
Xlib: unexpected async reply (sequence 0x5c07)!
------------------------------------------------
I got over the problem by compiling with following options
gcc -o out test.c `pkg-config --cflags --libs libgnome-2.0 libgnomeui-2.0
gthread`
Thank to Frank W. Miller for listing out the compilation and link steps
of the g_threads_init so clearly. This is exactly what works.
After successful compilation, I could never bring up the application: In fact
the main thread dumped with the following error at the very begning while
showing the very first screen
----------------------------------------
Thread1:
DH: create_login_window called
DH: DEBUG1
GLib-GObject-CRITICAL **: gtype.c:1875: initialization assertion failed, use
g_type_init() prior to this function
GLib-GObject-CRITICAL **: file gobject.c: line 615 (g_object_new): assertion
`G_TYPE_IS_OBJECT (object_type)' failed
------------------------------------------
So I added the following call
g_type_init();
Then I got the following Error:
------------------------------------------
DH: create_login_window called
DEBUG1
Gdk-CRITICAL **: file gdkvisual-x11.c: line 533 (gdk_screen_list_visuals):
assertion `GDK_IS_SCREEN (screen)' failed
----------------------------------------
I explicitly checked the return value of the gdk_screen_list_visuals()
function. It is NULL.
Please HELP.
Regards
Rita
The code is as follows:
main (int argc, char* argv[])
{
initialize_display(argc,argv)
}
