Hello.

I wrote a test scipt that uses the Tk.pm module on a server. I am just beginning to find uses for what Tk.pm has to offer.

The script is:

#!/usr/bin/perl

use Tk;
$win_main = MainWindow->new();
$win_main->title ("Main Window");
$button = $win_main->Button(text => 'OK', width => 10, height => 4);

$button->pack();
MainLoop();

When I invoked the script, I received the following message:

~~~~~~~~~~~~~~~~
_X11TransSocketUNIXConnect: Can't connect: errno = 2
_X11TransSocketUNIXConnect: Can't connect: errno = 2
_X11TransSocketUNIXConnect: Can't connect: errno = 2
_X11TransSocketUNIXConnect: Can't connect: errno = 2
_X11TransSocketUNIXConnect: Can't connect: errno = 2
_X11TransSocketUNIXConnect: Can't connect: errno = 2
couldn't connect to display ":0" at
../foo_path/5.005/i386-bsdos/Tk/MainWindow.pm line 55.
MainWindow->new() at testtk.cgi line 4

(notice - the path was changed here to a generic path)
~~~~~~~~~~~~~~~~
The reply I received from the sys admin was the following:

"That error signifies that the script can not connect to the Unix Xwindows system that you are logging in from. You do not have $DISPLAY set up properly in your .Xauth or rc files."
~~~~~~~~~~~~~~~~

How do I do whatever this response is telling me to do in order to use Tk.pm?

Thank you.
