Back when I was first setting up FVWM 1.24r, I remember the software
mentioning that it was 'motif compatible', and I ran some Motif
demo application at that time without difficulty.
Now I use FVWM2 and so far have been unable to get the CMUCL motif
debugger working, it just dies when the startup cannot get the socket
working. I seem to have a libXm, and have both lesstif and openmotif
installed.
Has anyone (not using MWM) gotten the CMUCL graphical debugger working?

I use twm and now ctwm and the motif debugger has almost always worked
for me to the point of popping up its window and pretending to do most
of the stuff I ask it to do.

I think I've tried it with fvwm2 long ago. It certainly displays ok
with gnome 1.x and gnome-whatever-comes-with-suse-9.
If it can't create the socket, it's probably not the fault of the
window manager in use.
Show us the error message.

Good to know that it will work, and I see that my ability to read
debugger messages has gotten better since I last tried this.

Ah, so it looks at .Xauthority, while the system is set with "xhost +".
No other user has problems getting X applications running (I see 5
users on this machine at the moment). If I load the clm-library as
root, it does popup a debugger window. Hopefully there is a flag I
can set to adjust the X security model inside clm.
Is the "Inspector" worth the effort to fix this? I like the idea
suggested in another reply about leaving the debugger as text and
enjoying the graphical Inspector, but I haven't tried it.

The source to clm seems to be available, someplace in the cmucl
tarballs. Given that, I can munge the .Xauthority request too and
look at the 'patch to use text debugger' idea.
The important fact was learning that it could work, thanks to all that
replied.

this is CMUCL's CLX implementation trying to read X11 authentication
information (CLM uses two connections with the X server, one for the
Motif library and one for CLX). CLX should really be ignoring the
Xauthority file if it's not readable; we should fix that for the
next release.
As a workaround for your situation, you could redefine the function
XLIB::GET-BEST-AUTHORIZATION always to return NIL.

Well the real problem appears to be what someone pointed out,
library:motifd: Symbol `_XmStrings' has different size in shared
object, consider re-linking
even as root, where the graphical debugger will work, my variables get
stepped on. I have Openmotif-2.1.30 installed, perhaps you linked
against a version 1 lib? I could recompile from source, but at the
moment this is not a pressing need. I started the thread because I
didn't have a clue what CLM debugger would do for me and wanted to try
it. At the moment, the text debugger is fine, I'm still in the
'gathering sticks for the first fire' stage with lisp, I can see that
I know most of what is required to convert my perl code (just need
some sockets practice and a way to hook into a packet capture ability).
I tried the redefinition, but apparently I don't know enough to
successfully pull that off, I got a series of errors, for instance:
CL-USER> (defun XLIB::GET-BEST-AUTHORIZATION () (return))
XLIB::GET-BEST-AUTHORIZATION
CL-USER> (defun square-1 (x) (x^2))

the following has a better chance of working:
(require :clm)
(setf (fdefinition 'xlib::get-best-authorization)
(lambda (a b c) (declare (ignore a b c)) nil))
(inspect *package*)
