Run a Cygwin (X) app from a DOS command line

Run a Cygwin (X) app from a DOS command line

[John Emmas]

Is it possible to run a Cygwin GUI app (i.e. requiring 'X') from a DOS
terminal, as opposed to a bash terminal?  After starting the X server
I tried  "cygstart path/to/my/program" but nothing happened.  The app
runs fine if I start it from a bash terminal.

John

You have to set the DISPLAY variable to a valid value.

You also need Cygwin's installation path in your Windows PATH variable.

Thanks Larry.  I already had that set up (C:\cygwin\bin) as well as
C:\cygwin\lib but I can still only launch console apps.  When this happened
for the very first time I seem to remember that "rebaseall" sorted it out.
Unfortunately, but that doesn't seem to fix the problem any more.

The required program is clearly getting launched because I can see it in
Task Manager - but it doesn't seem to get as far as putting anything on the
screen.

cygcheck -c  reports a few packages as being incomplete (including libX11 
and xorg-X11-bin).  I might try reinstalling them and see if that improves 
things.

Hi,

it seems to me that the application misses a running X server.

It is the same under Unix if you start an X application directly on a
console without having X running.
