Opened: 2007-10-08 01:33 0000
Description:   Opened: 2007-10-08 01:33 0000 
Emacs support is broken in all versions >=maxima-5.11.0-r2, last good version
was 5.11.0-r1 (which is no longer in the tree). To reproduce, type "M-x maxima
RET" in Emacs, which will result in an error message "Cannot open load file:
maxima".

The reason is that handling of the load-path was incorrectly changed between
revisions 5.11.0-r1 and -r2.

Attached patches will restore the previous behaviour and therefore fix the
problem.

Patch for maxima-5.13.0-r1.ebuild

This should be applied to all versions >=maxima-5.11.0-r2.

Created an attachment (id=132875) [details]
Patch for files/50maxima-gentoo.el

This will just undo the previous change to the site-init file.

------- Comment #3 From Ulrich Müller 2007-10-08 07:00:55 0000 ------- 
As an alternative to applying the two patches, one could call
    einstall emacsdir="${D}${SITELISP}/${PV}"

This would install the elisp files in /usr/share/emacs/site-lisp/maxima which
is the canonical location for Emacs.

Huh? Looks like you only removed the old versions, but didn't apply the
patches.

... neither applied the patches, nor took the solution of comment #3 (which
would also be valid).

thanks for the double check.

Stupid typo, this should be ${PN} instead of ${PV}. Corrected in CVS.
