Subject: 24.0.50; package--dir assumes that Emacs is installed
Date: Thu, 5 Aug 2010 18:07:39 +0000

When I compile Emacs from Git and run it without doing "make install" I
run into this in package.el:

    (unless pkg-dir
      (error "Internal error: could not find directory for %s-%s"
	     name version-str))

It's failing that assertion because package--dir assumes that Emacs is
already installed:

    package-directory-list is a variable defined in `package.el'.
    Its value is
    ("/usr/local/share/emacs/24.0.50/site-lisp/elpa"
"/usr/local/share/emacs/site-lisp/elpa")

It shouldn't do that. Usually Emacs runs fine if you build it and don't
install it.

I can't reproduce this.  I run Emacs in place without `make install',
and have not encountered any such error.  Could you provide a precise
description of the error, such as the error message shown in echo area?

It should not matter if these directories do not exist, but your bug
report does not provide enough information to tell for sure.

On a fresh Emacs checkout from git://repo.or.cz/emacs.git on both
Debian GNU/Linux testing and Debian GNU/kFreeBSD unstable doing:

    mkdir ~/g
    git clone git://repo.or.cz/emacs.git &&
    cd emacs &&
    make -j 10 bootstrap &&
    make

followed by:

    src/emacs

will display, in the echo area:

    "Internal error: could not find directory for package-1.0"

And in *Messages*:

    package-activate-1: Internal error: could not find directory for package-1.0

I've just glanced at the code, but it seems that it does
matter. package-activate-1 has this:

    (defun package-activate-1 (package pkg-vec)
      (let* ((name (symbol-name package))
             (version-str (package-version-join (package-desc-vers pkg-vec)))
             (pkg-dir (package--dir name version-str)))
        (unless pkg-dir
          (error "Internal error: could not find directory for %s-%s"
                 name version-str)

Which calls:

    (defun package--dir (name version-string)
      (let* ((subdir (concat name "-" version-string))
             (dir-list (cons package-user-dir package-directory-list)

package--dir is searching through (cons package-user-dir
package-directory-list), whose value on my system is:

    ("~/.emacs.d/elpa" "/usr/local/share/emacs/24.0.50/site-lisp/elpa"
"/usr/local/share/emacs/site-lisp/elpa")

None of those directories exist on my system. Perhaps you can
reproduce this issue if you delete your ~/.emacs.d/elpa directory?

Or maybe something is wrong on my system. I haven't looked deeply into
this bug, and I'd be happy to supply further info needed to solve it.

I don't see any error message with the Bzr repository; I don't know
about the unofficial git repository you are using.  You could try with
an empty .emacs file and no .emacs.d directory.

I should have tried with -Q, it turns out that I had this in my ~/.emacs:

    (setq package-activated-list nil)

I was defining it because a package I was using used it, but I hadn't
tried my ~/.emacs on Emacs trunk, so it wasn't compatible with a Emacs
that has package.el built-in.

Sorry about the noise. I think this bug can be closed.
