dev-python/pycairo-1.10.0-r1 was built with the following: USE="examples (multilib) svg -doc -test" Some preliminary investigation showed, that the patch files/py2cairo-1.10.0-svg_check.patch doesn't work as expected.
The relevant build log wouldn't be out of place here... But anyway, it's not quite the patch, that causes the problem, it's actually a quirk triggered by the build system/packaging. In src/ (only in py2 tarball, py3 is waf only), there's config.h.in and the generated by autotools config.h. Unfortunately, that means that during waf build there are two config.h and compiler picks one in src/ - without PYCAIRO_ENABLE_SVG definition. Trivial fix - 'rm "${WORKDIR}/${P}-${PYTHON_ABI}"/src/config.h' after copying py2 sources. Upstream may want to know.
(In reply to comment #1) > The relevant build log wouldn't be out of place here... Yeah, should have done that, sorry. I guess it isn't needed anymore? > ... > Trivial fix - 'rm "${WORKDIR}/${P}-${PYTHON_ABI}"/src/config.h' after copying > py2 sources. Yes, I can confirm that putting that line like this solves the problem: --- pycairo-1.10.0-r1.ebuild 2011-05-24 22:45:22.852530742 +0200 +++ pycairo-1.10.0-r2.ebuild 2011-05-24 22:45:12.062666390 +0200 @@ -37,6 +37,7 @@ popd > /dev/null pushd "${WORKDIR}/py2cairo-${PYCAIRO_PYTHON2_VERSION}" > /dev/null + rm src/config.h || die epatch "${FILESDIR}/py2cairo-1.10.0-svg_check.patch" popd > /dev/null
I can confirm that Henry's fix works.
Created attachment 277391 [details] build.log Here's a build.log
Had the same problem and the suggested fix worked for me too.
Fixed in python overlay.
I've committed this fix to the portage tree (I've made a similar fix to the Python 3 version of the code, I hope that works the same way). I don't think reporting to upstream makes sense here, since the way we do the svg use flag selection seems kind of gentoo-specific.
(In reply to comment #7) > (I've made a similar fix to the Python 3 version of the code, I hope > that works the same way). There is no src/config.h in tarball for Python 3 version of pycairo.
