gnuplot installation requires a specific version of Emacs.app

[marc.shapiro@…]

installing gnuplot fails with my Emacs.app installation. It is strange that it requires Emacs and even stranger that it requires a specific Emacs installation

Making all in lisp
emacs -batch -q -no-site-file -l ./dot.el -f batch-byte-compile gnuplot.el
Warning: arch-dependent data dir (/Volumes/Emacs/Emacs.app/Contents/MacOS/libexec/emacs/22.1.50/powerpc-apple-darwin8.10.0/) does not exist.

That looks like it might be hard-coded to use ​Aquamacs. What's your emacs environment? I'm curious where those directories come from ... is it your emacs environment or your build environment for gnuplot?

[cssdev]

What's your output from "which emacs"? It's not clear exactly which emacs binary is being used during the port's build process.

Patch to add +emacs and specify an explicit lispdir

[mojca (Mojca Miklavec)]

I added a patch which should solve #27996 and #33554, but I'm not sure if it also solves the particular issue in this ticket.

Maybe one also needs

configure.env EMACS=${prefix}/bin/emacs

if another emacs takes precedence in PATH. It seems to me that lispdir is determined with something like

$EMACS -batch -q -eval '(while load-path (princ (concat (car load-path) "\n")) (setq load-path (cdr load-path)))' </dev/null >conftest.out

but I'm not sure how to test all the different combinations and border cases.

[mojca (Mojca Miklavec)]

And, as noted in my email to the development mailing list, some ports do the following:

variant emacs_app description {Use this package with Emacs.app} {
    depends_lib-delete  path:bin/emacs:emacs
    depends_lib-append  path:${applications_dir}/Emacs.app/Contents/MacOS/Emacs:emacs-app

    set dir_info    ${applications_dir}/Emacs.app/Contents/Resources/info
    configure.env   EMACS=${applications_dir}/Emacs.app/Contents/MacOS/Emacs
    configure.args  --with-lispdir=${applications_dir}/Emacs.app/Contents/Resources/site-lisp/${name} \
                    --infodir=${dir_info}
}

so we would need that extra code to be able to support people with Emacs.app instead of plain emacs. Is that needed?

Replying to myself: there is currenty one problem:

The following line has to be deleted before applying this patch:

destroot.destdir            prefix=${destroot}${prefix}

See also #32872.

[mojca (Mojca Miklavec)]

The second patch which removes destroot.destdir (an optional second part cleans up old files that might be still around), see also #32872

[mojca (Mojca Miklavec)]

The patch ​patch-gnuplot-emacs2.diff should be able to fix the issue with files not belonging to any package. The second part (deleting files) is optional and I leave it up to other developers whether to include it or just tell users to remove files manually when present (I don't expect many users to be hit).

The patch for #32872 is a bit related, but I need some feedback/brainstorming about that one first before writing a patch.
