cedet fails to build when you try and emerge jde which isn't surprising as it got merged into emacs at 23.2. Reproducible: Always Steps to Reproduce: 1. emerge a modern emacs (>= 23.2) 2. emerge app-emacs/jde 3. what cedet fail to compile
Created attachment 295487 [details, diff] Don't depend on CEDET if we have a more modern emacs CEDET was merged into emacs at 23.2.
Annoyingly that patch on it's own doesn't work as I need to somehow change the eant bindist call if a newer emacs exists to pass the correct CEDET path.
There's also virtual/emacs-cedet which could be used in DEPEND.
(In reply to comment #3) > There's also virtual/emacs-cedet which could be used in DEPEND. That would make more sense. However the cedet.dir variable passed to the jdee build will be different depending on which version of cedet you use. What's the best way to handle this in the ebuild?
IIRC, cedet.dir is only used at build time? (Otherwise there would be a problem after each Emacs update.) Then its location could be determined as follows: local cedet cedet=$(${EMACS} ${EMACSFLAGS} --eval '(princ (locate-library "cedet"))') cedet=${cedet%/*} # get directory part [[ -n ${cedet} && -d ${cedet} ]] || die "CEDET not found"
Created attachment 295601 [details, diff] Updated patch, using emacs to find location of cedet files for build Changes: Use virtual/cedet Use emacs to get location of cedet for build
Created attachment 295611 [details, diff] Update to the updated patch It's virtual/emacs-cedet, not virtual/cedet
I fear it's not so easy, at least I'm getting several errors during compilation: [exec] Compiling /var/tmp/portage/app-emacs/jde-2.4.0.1-r1/work/jde/build/lisp/jde-bookmark.el... [exec] [exec] In toplevel form: [exec] jde-bookmark.el:33:1:Error: Cannot open load file: semantic-sb The reason for these failures is that the names of CEDET's files were changed when it was included with Emacs. For example, cedet/semantic-sb.el has become cedet/semantic/sb.el. (AFAIR, the reason for this renaming was compatibility with 8+3 filenames on MS-DOS ...) Looking into the SVN repository at <http://jdee.svn.sourceforge.net/viewvc/jdee/trunk/>, it seems that at least some of these problems have been addressed upstream. So maybe it's better to make a snapshot from there, instead of bothering with 2.4.0.1.

Created attachment 295637 [details] jde-2.4.1_pre20110622.ebuild (In reply to comment #9) > A app-emacs/jde-9999 for building straight out of the SVN? A snapshot is much preferred over a live ebuild. In fact, I've put a jde-2.4.1_pre20110622.tar.gz on Gentoo mirrors already, taken from <http://jdee.svn.sourceforge.net/viewvc/jdee/trunk/jdee/?view=tar&pathrev=254>. My attempt of an ebuild is attached. I'm still getting one compilation error though (occuring several times): Error: Symbol's function definition is void: jde-find-jde-doc-directory Another question is why eant signals a successful build, in spite of these errors?
Created attachment 295639 [details] build.log Here's the build.log for the ebuild from attachment 295637 [details].
jde-2.4.1_pre20110622 committed to CVS. I had to add two more patches, one for the issue with jde-find-jde-doc-directory mentioned above, and another one to make it work with emacs-vcs-24.0.92. Please test.
