[chord] about VIS in the text mode:Gtk-WARNING **: cannot open display:

[wen winsen]

Hi,ALL:
  At first thank you very much.Setuping and configuring chord after 
installing GTK2.0, I can find the vis in the devel sub-directory of my 
build tree.

some configure message:

checking GSTUFF_CFLAGS... -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include 
-I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/X11R6/include 
-I/usr/include/freetype2 -I/usr/include/glib-2.0 
-I/usr/lib/glib-2.0/include
checking GSTUFF_LIBS... -Wl,--export-dynamic -lgtk-x11-2.0 -lgdk-x11-2.0 
-latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangoxft-1.0 -lpangox-1.0 -lpango-1.0 
-lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0
configure: WARNING: Found GTK...

But when I run vis,it appears the followed:

[root at mrtest devel]# ./vis -j sure.lcs.mit.edu:10000 [-a sec] [-f color 
file]
(vis:14089): Gtk-WARNING **: cannot open display:

My linux is REDHAT 9 with TEXT mode and I don't install the Xwindows 
module.Must the GTK run in the X mode? If i run VIS in the text mode,what 
modules I need to install? I have not  found some good ways to fix this 
warning with GOOGLE.

Best Regards!
Winsen
