[sdl.web@gmail.com: load-path missing?]

[Richard Stallman]

He is talking about Unicode-2, but could someone please
check whether this happens with the current pretest?
Please respond with the answer.

Hi all,

Compiling Emacs on my new Fedora Core 6 reveals something
interesting. Here is another one about load-path.

My configure options are as follows:

,----
| ./configure --prefix=/usr/local/packages/emacs
| --enable-locallisppath=/usr/local/share/emacs/site-lisp
`----

After install, I see this directory tree:

PREFIX/share/emacs:
                |--> site-lisp
                \--> 23.0.0
                        |--> site-lisp
                        |--> lisp
                        |--> leim
                        \--> etc

However those two site-lisp dirs are not in the load-path. Is this
intentional?

It does not happen with Emacs 22.

I built Emacs 22.0.92.1 (2006.12.24). Seems to me it does.

/home/leo/packages/emacs22/share/emacs/site-lisp
/home/leo/packages/emacs22/share/emacs/22.0.92/site-lisp

exist but are not in the load-path as follows.

OK now I understand the problem.  You're right, this situation exists.

I'm not sure this causes any problems, however.  Using
enable-locallisppath implies you are using another set of site-lisp
directories, but its documentation (from configure --help, which is
the only place this option is mentioned) is rather vague:

  directories Emacs should search for lisp files
  specific to this site

so it's plausible that the site-lisp directories are created but not
used, since the user is specifying another set of site directories to
look at instead.

It seems to me harmless to let this situation be.  I don't know if
either not creating the directories or adding them to load-path will
break any existing installations.

It didn't create any problems. But it confuses users because those
directories have a name indicating they are in the load-path. What if
Emacs is compiled with 'configure --prefix=/usr
--enable-locallisppath=...' then /usr/share/emacs/site-lisp will be
created and contain subdirs.el, but not in load-path.

    My configure options are as follows:

    ,----
    | ./configure --prefix=/usr/local/packages/emacs
    | --enable-locallisppath=/usr/local/share/emacs/site-lisp
    `----

I think what is going on is that configure sets up src/epaths.h based
on the value you specified for locallisppath, which overrides
the value that would have been computed from --prefix.

Is that right?

I guess it is not completely overridden since those 'site-lisp' dirs
are still created and even contain subdirs.el.

I'd propose to have PREFIX/share/emacs/22.0.92/site-lisp included just
like PREFIX/share/emacs/22.0.92/lisp, and PREFIX/share/emacs/site-lisp
be the default value to --enable-locallisppath.

That's the point.  The code that creates these directories does not
get the names from your specified locallisppath.  It constructs the
names based on PREFIX.

    I'd propose to have PREFIX/share/emacs/22.0.92/site-lisp included just
    like PREFIX/share/emacs/22.0.92/lisp, and PREFIX/share/emacs/site-lisp
    be the default value to --enable-locallisppath.

PREFIX/share/emacs/site-lisp _is_ in the default value for
locallisppath.  But you specified a different value
so you did not get the default.

It is not clear from `configure --help' what's the default value to
--enable-locallisppath.

Is `PREFIX/share/emacs/22.0.92/site-lisp' also a default value to
--enable-locallisppath? If the answer is NO, is it supposed to be in
the load-path?

Anyway, if another set of load-path is specified in
--enable-locallisppath, the existence of
PREFIX/share/emacs/22.0.92/site-lisp and PREFIX/share/emacs/site-lisp
does nothing but confusing user.

    It is not clear from `configure --help' what's the default value to
    --enable-locallisppath.

You can't expect the --help output to go into such detail.

(Meanwhile, it seems to me that the name --enable-locallisppath
conflicts with the GNU standards for configure arguments.)

    Anyway, if another set of load-path is specified in
    --enable-locallisppath, the existence of
    PREFIX/share/emacs/22.0.92/site-lisp and PREFIX/share/emacs/site-lisp
    does nothing but confusing user.

Would someone like to change Makefile.in so that it creates the
directories given in locallisppath, rather than those two directories
specifically?
