AltGr in command key sequence not working

AltGr in command key sequence not working

[Sebastian Schubert]

Hi,

I use a self-compiled Emacs 21.4.1 on a Suse 9.2 system under X. I have to
push e.g. AltGr-8 to get [ (German keyboard). Just entering that works fine
but I can't use any command sequence including a symbol I can only get with
AltGr. C-h k AltGr gives me "<key-3> is undefined".

What can I do?

Thanks
Sebastian

Get a decent keyboard layout, like US -- or better -- Dvorak. The German 
one IS a bug. ;)

Viele Grüße, Ulrich (der erst nach USA, dann nach Dvorak geswitcht hat)

Ok, but that's rather a workaround then a solution. I somehow like WYSIWYG
keyboards. Emacs is so old, there should be a way to solve that problem.

Or isn't it a problem of emacs? I found that on
http://lists.gnu.org/archive/html/bug-gnu-emacs/2004-10/msg00150.html

 If Emacs (nearly all version from last years) is compiled with xorg-x11
 and it is used with European keyboard with AltGr key, pressing AltGr
 beeps and breaks i-searches.
 
 Bug is not in Emacs, but in X:
 http://freedesktop.org/bugzilla/show_bug.cgi?id=1625
 
 But Emacs can include simple work-around:

What does it mean? Somehow change src/xterm.h, I guess.

Thanks

It means to move the line with <X11/Xutil.h> from its original position 
before keysym.h to the new position after keysym.h, in 
emacs/src/xterm.h. Xutil.h seems to make some valuable changes and 
introduce valuable macros, but these obviously need some preparation 
from keysym.h -- or keysym.h is destroying the "values" which were 
introduced by Xutil.h ...

Here is an excerpt from emacs/src/xterm.h from CVS:

	#include <X11/Xlib.h>
	#include <X11/cursorfont.h>
	
	/* Include Xutil.h after keysym.h to work around a bug that prevents
	   correct recognition of AltGr key in some X versions.  */
	
	#include <X11/keysym.h>
	#include <X11/Xutil.h>


So we should recommend to use a pretty modern GNU Emacs, one from last 
few months, GNU Emacs 21.4?  This might be correct for X11, but what 
with those unhappy few with MS what thing?

It works! Thanks!

This one does not include the fix, just mentioning this small fix somewhere
easy to find would be nice. Most of the recent Linux distributions use
X.org AFAIK.

Thanks!
