Re: How to run ddd in XWin?

[Igor Pechtchanski <pechtcha at cs dot nyu dot edu>]

Ok, you're now in the Cygwin/X territory.  Any questions about Cygwin/X
should be addressed to the cygwin-xfree mailing list (specifically set up
for this topic).  For your convenience, I've redirected this reply to that
list, and set the Reply-To: appropriately.  More below.

Nope.  Why should documentation for a generic X server, XWin, talk about a
particular X application, ddd?

Which "same error"?  Be specific.  Is it the "can't open display" error?
You need to set the DISPLAY variable properly.  The default value for the
command line above should be ":0" (or ":0.0").  You can set the DISPLAY in
a bash console window, e.g., "export DISPLAY=:0", before invoking ddd.

No idea.
