Trouble building against Emacs23 OSX

Trouble building against Emacs23 OSX

I built emacs23 from source on OSX and placed Emacs.app into my
/Applications/ directory.  Everything works great, except for trying to
build things against it.

w3m apparently cannot be built against emacs22 and work in emacs23.

Since the most current version of emacs in /usr/bin is emacs22, I mv'd it
and ln'd /usr/bin/emacs to /Applications/Contents/MacOS/Emacs.  

Now, when running configure for w3m it sees that I'm using emacs23, but it
cannot find simple.el, simple.elc, etc.:

Can anyone offer up any help on this?  I cannot find a libexec/emacs/23.1.50
anywhere on my system.

Thanks in advance,

Devin

Could you try to set the appropriate environment variable rather than creating a symlink into the application bundle?

Usually, it is something like

export EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs

That fixed it.

Thanks much, David.

There is another strategy that I've found helpful for OS X.  I have a
one-line shell script installed as
/Applications/Emacs.app/Contents/MacOS/bin/emacs:

   $ cat /Applications/Emacs.app/Contents/MacOS/bin/emacs
   #!/bin/sh
   exec /Applications/Emacs.app/Contents/MacOS/Emacs -nw "$@"

Then, I prepend /Applications/Emacs.app/Contents/MacOS/bin to PATH.

With these two steps, you should be able to build any extra lisp
packages "out of the box", and you'll get the correct versions of
helper programs like emacsclient and etags.

When you want to run emacs as a windowed application, use
"open /Applications/Emacs.app".  Open will propagate your shell's
environment to the windowed emacs.
