I've confirmed that can be compiled in the following way. CC=clang CXX=clang++ CFLAGS="-O2 -pipe -Wno-format-nonliteral" \ CXXFLAGS="-O2 -pipe -Wno-format-nonliteral" emerge dev-libs/glib
Created attachment 354392 [details, diff] sample patch for glib-2.36.3-r1.ebuild
As this only affects clang, I would include it. Feel free to commit in a week if nobody disagree
Patch looks good. However if gcc is going to fix this, maybe the could have that "fix" applied to all compilers, right ?
+ 29 Sep 2013; Pacho Ramos <pacho@gentoo.org> glib-2.36.4-r1.ebuild: + Support compilation in clang until upstream solves this, upstream bug #691608 + (#478338 by Yuta SATOH) +
