Cygwin emacs - does it work?

Cygwin emacs - does it work?

[Lennart Borgman (gmail)]

I just out of curiosity installed Cygwin Emacs. Now I am more curious 
about why this version of Emacs is there.

For me nearly nothing works in this Emacs. For example typing C-c 
results in C-g. Trying to examine a variable results in the error 
message "Cannot open load file: pp". Trying to send a bug report I am 
told that Emacs can not load emacsbug. Etc.

The about page says

   GNU Emacs 22.1.1 (i686-pc-cygwin)
    of 2007-07-19 on HERRING

Is there anyone to contact about this?

It certainly _used_ to work just fine, and is of course quite useful for
using with a cygwin installation.

I've only installed it from the standard cygwin package though...
[about 7 months ago]

I don't have a windows system now though.

I have installed it from the setup.exe that comes with cygwin. When you 
say that it worked 7 months ago it reminds me that there was a new 
release of the cygwin dll in may. Since I see things like C-c beeing 
recieved by Emacs as C-g I guess that the new dll can be the problem.

It is however also an old version of Emacs they are distributing.

I just installed the cygwin Emacs for X. I have never used X. When I try 
to start Emacs now I get the rather incomprehensible:

   $ emacs
   emacs: Cannot connect to X server localhost:0.0.
   Check the DISPLAY environment variable or use `-d'.
   Also use the `xhost' program to verify that it is set to permit
   connections from your machine.

What?

Which package have you installed?

In Cygwin the current version of Emacs is 21.2-13, instead 22.1 is in 
the test section, i.e. it is an experimental package.

It is more than an year that it is there without being promoted to 
current because people reported it crashes (see [1] and its replays).

The fact is that since version 22 Emacs is unstable when built with 
gcc-3.4.4 (the current version on Cygwin) and its maintainer on Cygwin 
is waiting for 4... series, with which it is enough stable. Perhaps this 
explain why 22.2 isn't neither in test version.

Following [1], you can find other useful information.


Cheers,
    Angelo.

Thanks David, that worked. And the (old) Emacs for X could be started. 
However it is version 21.

The first I installed was

   Editors
     emacs: The extensible, customizable ...

That is the one which has the problems I reported above.

Then later I installed the X version

   Editors:
     emacs-X11: ...

This works (as far as I tested, I do not know Emacs 21 very well).

Thanks, I see, but then perhaps the package I installed should be 
removed, because it does not work either (at least not for me).

I think you need to set an environment variable before starting Cygwin
-- "set CYGWIN=tty" might do it.

In general though, I've found Cygwin emacs to be too frustrating to use;
I instead use the native Win32 emacs, but with lots of Cygwin tools such
as bash, coreutils, and find.

That is frustrating too ;-)

Why 'frustrating'?

I start the GTK build of Emacs trunk (and the X server if needs) with a 
link on the Desktop.

The target of the link is:

C:\cygwin\bin\run.exe bash -l start_emacs-X.sh

and

$ $ cat /usr/local/bin/start_emacs-X.sh
#!/bin/bash

#export DISPLAY=127.0.0.1:0.0
export DISPLAY=:0

#export PATH=/usr/X11R6/bin:"$PATH"
# export XAPPLRESDIR=/usr/X11R6/lib/X11/app-defaults
# export XCMSDB=/usr/X11R6/lib/X11/Xcms.txt
# export XKEYSYMDB=/usr/X11R6/lib/X11/XKeysymDB
# export XNLSPATH=/usr/X11R6/lib/X11/locale

## --------------------------------------------------------

start_XWin()
{
     # Cleanup from last run.
     rm -rf /tmp/.X11-unix

     XWin -multiwindow -clipboard -silent-dup-error +bs &
}

/usr/bin/checkX || start_XWin

## --------------------------------------------------------

## Workaround to use GTK build of Emacs
export G_SLICE=always-malloc

exec /usr/local/bin/emacs

==================================================================

The link can be created automatically running:

## Emacs
mkshortcut -A \
     -n Emacs \
     -D /usr/bin/run.exe \
     -a 'bash -l start_emacs-X.sh' \
     -i /usr/local/bin/emacs.ico \
     -d "Editor di testo" \
     -w ''


Cheers,
    Angelo.

I use this for reading email with Gnus at work, because the mail
server requires 'starttls', which I could only get to work via Cygwin.

You need to start the X server first. I use:

export DISPLAY=127.0.0.1:0.0

XWin -clipboard -multiwindow -multimonitors -silent-dup-error -logverbose 0 &

Thanks. That made it a bit more clear.
