Cannot open load file: disp-table - error running batch with EMACSLOADPATH

Cannot open load file: disp-table - error running batch with EMACSLOADPATH

[Drew Adams]

If I define environment variable EMACSLOADPATH (as anything at all - whether
a correct path or not), I can't seem to get emacs to run in batch.

I'm running emacs 20.7 on Solaris. Actually, I run an xterm (with or without
a window manager) on the box remotely, using Tarantella.

Emacs works fine interactively; I just can't use it in batch mode with
variable EMACSLOADPATH. If EMACSLOADPATH is undefined, I can run emacs OK in
batch (but of course I can't load libraries, then).

If EMACSLOADPATH is defined at all, I get this error:

  Cannot open load file: disp-table

disp-table is not a library of mine that I load (consciously). It appears to
be a built-in library that is getting loaded by default. The only occurrence
of disp-table in the info help is in a discussion of "Single-byte European
Character Support".

It doesn't matter what the options to emacs -batch are, and it doesn't seem
to have anything to do with any site file:

  emacs -batch
  emacs -batch -q          [-batch should imply -q anyway]
  emacs --no-site-file -batch -eval '(message "hello")'
  emacs -nw --no-site-file -batch -eval '(message "hello")'

  emacs -batch -l mylib
  emacs -batch -l mylib -f myfun

These all give the same error when EMACSLOADPATH is defined. The first four
work OK when it is not defined (the last two need a load-path).

Anyone have an idea on this?

What value do you have EMACSLOADPATH defined to?  If it doesn't
include the standard Lisp directory where disp-table.elc lives, you
will indeed see the error message.

What happens is that setting EMACSLOADPATH overrides the built-in
value used by Emacs to look for Lisp files.  If you still want Emacs
to find its bundled Lisp files, you need to make sure that
EMACSLOADPATH includes the directories where those bundled files live.

So in an interactive session, type `M-x locate-library RET disp-table
RET'.  Then make sure its directory is in EMACSLOADPATH when you run
Emacs in batch mode.
