Whenever I add:

    (require 'flymake-js)
    (add-hook 'javascript-mode-hook 'flymake-js-load)

to my '.emacs' file and then 'eval-buffer', I get this error:

    append: Symbol's value as variable is void: compilation-error-
regexp-alist-alist

Thank you in advance.

i don't see flymake-js.el anywhere in the emacs source, so the
following is a guess, from studying (briefly) flymake.el:

the variable compilation-error-regexp-alist-alist is defined in
compile.el.  try adding (before the forms above):

(require 'compile)

long term it would probably be a good idea to see what
flymake-js.el offers that flymake.el doesn't and merge those
features into flymake.el.

Looks like there was an error in 'flymake.el' -- looks like they had
typed an extra '-alist'? See code and comment I put in my local copy:

be an error.             -- cbalz 2008-01-23

Using 'M-x describe-variable', I get the correct definition for
'compilation-error-regexp-alist'.

Yet now that 'flymake-js.el' runs without error and starts up (showing
on the modeline), I get this problem, which totally removes Emacs'
ability to save files!  Any idea here?

File mode specification error: (error "IO error writing z:/work/det-us/

From the frying pan to the fire!
