That's interesting. To answer your question, perhaps if you do

       ldd `which emacs`

then you can see if it's linked against things like libX11.

I can't be sure that text-only ones wouldn't be, but I'd guess that they
mightn't. (-:

Does the ssh daemon on your desktop allow X forwarding? For instance, my
sshd has a config file with a X11Forwarding option that I have to set
to 'yes' for X forwarding to be permitted.

(Apologies for the Unix/Linux-centric view, if you're a Windows user.)

It appears that it isn't linked against any X libraries.  My next question
would therefore be how I could modify the program to link against such
libraries.

Other programs have successfully forwarded.  The specific example I used was
xpdf.

Install a C compiler and install the X11 developer packages. Then  
configure GNU Emacs with '--with-x' and look at the end of  
configure's output. There it should be mentioned that X libraries  
where found:

   What window system should Emacs use?                    x11
   What toolkit should Emacs use?                          LUCID
   Where do we find X Windows header files?                /usr/X11R6/ 
include
   Where do we find X Windows libraries?                   /usr/X11R6/ 
lib

Then compile and install!

If configure did not find X, then better get a pre-compiled version.

Okay, we'll assume you have no X forwarding problems then. (-:

You'd probably have to get a different version from wherever that emacs
came from, or recompile it with different options if it was compiled
with source. If you need more help then: What sort of system is it that
this emacs is living on? Where did the emacs come from?

(I assume it probably isn't statically linked with libX11.)

X commands not forwarding

[lackita]

I'm sshing into a computer and wanted to forward the X commands to my desktop
for obvious reasons.  The problem is that it always runs as if it has the
-nox option.  I can get other programs to tunnel, so I know it's not a
problem with my x server.  It's possible that this is a version of emacs
without X capabilities, so could somebody tell me how to check for that as a
starting point.

In a shell:
ldd /usr/local/bin/emacs | grep libX

In Emacs, the splash screen or `M-x emacs-version' displays the X
toolkit it was built with (if any).
