"cannot open display"

"cannot open display"

[Ogogon !!!]

Good afternoon, colleagues!

I have established CygWin to compile under Windows the program developed 
in gcc. At compilation of console applications - all OK. All 
applications, even rather complex, are started and work without remarks.

However, any attempt to create the program with GTK+, leads to that at 
their start there is a message "Gtk-WARNING **: cannot open display:".
At distribution kit CygWin there is a program gtk-demo.exe. Obviously, 
it it is guaranteed it is compiled without mistakes. It is not started 
and also writes "Gtk-WARNING **: cannot open display:".

My OS - WindowsXP Pro (Rus). What do I do incorrectly?

Yours faithfully,
Ogogon.

Then it is probably an X problem, and you asked the wrong list.  Try
cygwin-xfree; redirecting accordingly.

Probably forgot to set up X.  And also didn't follow these directions:

Including the output of 'cygcheck -svr' as a text attachment would have
told us what the real problem was.

Hi,
is the EnvVariable "DISPLAY" set to the right display, e.g.
"127.0.0.1:0.0" AND is some sort of XServer running?
