Re: byte-compile-file: emacs vs the command line.

[R. Clayton]

Why is the command-line compile failing, and how can I fix it?

  require uses load, and running in batch doesn't load init files.  This means
  load-path doesn't contain everything it should to load local files.  The fix
  is to fix load-path:

    $ cat rm.el
    (require 'general-utils)

    $ emacs --batch --exec '(byte-compile-file "rm.el")'

    $ 

  There are probably other ways to fix load-path - loading the init files, for
  example.
