Created attachment 406352 [details, diff] "pre-patch" which has to be applied after failure (/var/tmp/portage/sci-mathematics/octave-4.0.0/work/octave-4.0.0/doc/interprete r/cp-idx.texi (Concept Index) [923] [924] (./octave.cps ./octave.cps:56: Argument of \\ has an extra }. <inserted text> \par <to be read again> } \initial ... .5\baselineskip \leftline {\secbf #1} \nobreak \vskip .33\baseli... l.56 \initial {\\} ? ./octave.cps:56: Emergency stop. The problem is that \\ is a LaTeX macro. Unfortunately, I cannot come up a with a patch, but after emerge has failed cd /var/tmp/portage/sci-mathematics/octave-4.0.0/work/octave-4.0.0 and apply the attached "pre-patch" Then an ebuild /usr/portage/sci-mathematics/octave/octave-4.0.0.build merge succeeds.
Can you please let us know the output of: equery list virtual/latex-base dev-texlive/texlive-genericrecommended dev-texlive/texlive-metapost sys-apps/texinfo The build.log might give some hints. Maybe we need to require higher versions of the doc dependencies, as it builds fine with doc for me with: # equery list virtual/latex-base dev-texlive/texlive-genericrecommended dev-texlive/texlive-metapost sys-apps/texinfo * Searching for latex-base in virtual ...

Ok, it's the texinfo version. Building with texinfo-5.2 succeeds. It seems the handling of backslashes in texinfo macros is changing between releases. Looking at the ChangeLog of texinfo and some mailing list discussion, they seem to have serious problems handling the use of backslashes in macro definitions, adding a \fixbackslash, \enablebackslashhack, ... http://svn.savannah.gnu.org/viewvc/*checkout*/trunk/ChangeLog?root=texinfo Haven't yet figured out how to fix this properly, I'm on it.

Thanks, it seems I am doing something wrong since I can't reproduce the problem with sys-apps/texinfo-6.0. This thread says the ancient bundled doc/texinfo.tex should be removed: https://lists.gnu.org/archive/html/bug-texinfo/2015-07/msg00035.html In the hg repo I searched for commits like: hg log -k tex | less Which finds these 2: changeset: 20318:45d7be391982 branch: stable user: Mike Miller <mtmiller@octave.org> date: Thu Jul 09 21:45:26 2015 -0400 summary: build: Use texinfo.tex from gnulib instead of manually imported version changeset: 20317:2ec049e50ed8 branch: stable parent: 20314:3300cb76cccd user: Mike Miller <mtmiller@octave.org> date: Thu Jul 09 21:44:09 2015 -0400 summary: doc: Fix backslash characters in docstrings Which are here: http://hg.savannah.gnu.org/hgweb/octave/rev/2ec049e50ed8 http://hg.savannah.gnu.org/hgweb/octave/rev/45d7be391982 So the attached patch applies these 2 commits, except we rm doc/texinfo.tex in the ebuild as that shortens the size of the patch: argus / # diff -ur /usr/portage/sci-mathematics/octave/octave-4.0.0.ebuild /usr/local/portage/sci-mathematics/octave/octave-4.0.0.ebuild --- /usr/portage/sci-mathematics/octave/octave-4.0.0.ebuild 2015-08-26 17:01:02.000000000 +1000 +++ /usr/local/portage/sci-mathematics/octave/octave-4.0.0.ebuild 2015-09-05 12:22:47.699513276 +1000 @@ -100,6 +100,11 @@ -e 's@A-Za-z0-9@[:alnum:]@g' \ -e 's@A-Za-z@[:alpha:]@g' \ libinterp/mkbuiltins || die + + # Fix bug 554226 - sci-mathematics/octave-4.0.0 fails because of a LaTeX error + epatch "${FILESDIR}"/${PN}-4.0.0-texinfo.patch + rm -f "${S}"/doc/texinfo.tex + autotools-utils_src_prepare } argus / # It would be neat if you could test this please, thanks!
