gnuplot works fine after removing the mentioned line from the ebuild. If it is ignored, what is the point of having an emacs useflag anyway?
I think this bug 366129 is the reason for it. Without emacs/xemacs/texinfo, the pre-generated documentation files WERE outdated in a PREVIOUS release. From that bug: > Watch out for the following message in build.log: "No emacs found - cannot > create texinfo file" But I don't see this show up. Some people don't have any emacs-related packages installed for religious reasons, and Gentoo should respect that. :)
(I should say, I didn't see that show up after removing the dependency from the ebuild manually.)
(In reply to comment #0) > This line is responsible: > !emacs? ( !xemacs? ( || ( virtual/emacs app-xemacs/texinfo ) ) ) This dependency is correct: Either GNU Emacs or XEmacs is needed as dependency for building gnuplot.texi from gnuplot.doc (even in the USE="-emacs -xemacs" case). See docs/Makefile.in: $(srcdir)/gnuplot.texi: $(srcdir)/doc2texi.el $(srcdir)/gnuplot.doc @echo "Creating texinfo" @if test "$(EMACS)" != no; then \ cd $(srcdir) ; \ $(EMACS) -batch -l doc2texi.el -f d2t-doc-to-texi ; \ else \ echo "No emacs found - cannot create texinfo file" ; \ fi The distributed tarball comes with a pre-built gnuplot.texi, so for the regular ebuilds the build-time dependency could be lifted. However, it is still needed for the live ebuild.

@ulm: Thanks for fixing it! I will sync it with sci overlay later. I am still a bit unhappy with EMACS=$(usev emacs || usev xemacs || echo no) as it will not build texi doc (and fail) in case that all emcacs' are disabled, but one of them is still installed (due to DEPEND) I guess EMACS=no is fine for all non-live ebuilds, but live-ebuild need the check with has_version. Let's keep that change for rc2 ;-)
Hm, I think that USE flags should have highest priority to determine what Emacs will be used. But we could fall back to the has_version heuristics in case of the live ebuild with USE="-emacs -xemacs". The following should work: local emacs=$(usev emacs || usev xemacs || echo no) if [[ -z ${PV%%*9999} ]] && [[ emacs = no ]]; then if has_version virtual/emacs; then emacs=emacs elif has_version app-xemacs/texinfo; then emacs=xemacs fi fi
Can't you just do the following? if [[ "${PV}" = *9999* ]] ; then DEPEND="${DEPEND} !emacs? ( !xemacs? ( || (...) ) ) fi
(In reply to comment #8) > Can't you just do the following? > > if [[ "${PV}" = *9999* ]] ; then > DEPEND="${DEPEND} !emacs? ( !xemacs? ( || (...) ) ) > fi Ulrich, has done exactly that! It is more a question, which emacs to use in the live ebuild if both are disabled.
