I tried to compile the following sample tutorial code on Red Hat 8.0, with 

>gcc test.c -o test1 `gnome-config --cflags --libs gnomeui`

The output is an error message "undefined reference to gtk_Widget_show".

Please advice how to solve this problem in order to produce an empty window.

I assume that RH 8.0 has all the gnome libraries. 

sample code is :

#include <gnome.h>

int main (int argc, char *argv[])
{
 GtkWidget *app;
 gnome_init("example","0.1",argc, argv);
 app=gnome_app_new("example","Window Title");
 gtk_Widget_show(app);
 gtk_main();
 return 0;
}

Hi ga1000-ga,

Identifier names are case-sensitive in the C programming language, and
your error message is caused by a spurious uppercase letter.

If you change 'gtk_Widget_show' to 'gtk_widget_show' then your example
should work. I tried it on my RedHat 8.0 system and it produced an
empty window, as expected.

Note that you are not calling 'gtk_main_quit' in your example code. If
you launch your compiled example from the command-line (for example by
typing './test' in a console window) you will probably have to press
control-C to regain the command prompt (even after you have closed the
window of the example application). For a more complete introductory
example including a clean shutdown see "Hello World in GTK":
http://www.gtk.org/tutorial/ch-gettingstarted.html#SEC-HELLOWORLD

The 'gtk_widget_show' identifier is defined in file 'gtkwidget.c',
according to the Gnome Cross Reference search
http://cvs.gnome.org/lxr/ident?i=gtk_widget_show
which provides a handy way to find usage examples for any GTK
identifier.
