Created attachment 475270 [details] build.log When doing a normal emerge -avuND --with-bdeps y @world, I am unable to get podofo to rebuild. I have attached the build.log, my emerge --info, and emerge -pv podofo as attachments. I do see the reference to C++2011. I'm not sure if this has to do with the move to GCC5. I did run the revdep-rebuild command from eselect news and it recompiled a ton of packages, so I don't think it would be that. Any help would be appreciated. Thank you!

The error suggests that cppunit didn't get rebuilt yet, can you try this command to see when it was last successfully built? date -d @$(</var/db/pkg/dev-util/cppunit-*/BUILD_TIME)
% date -d @$(</var/db/pkg/dev-util/cppunit-1.14.0/BUILD_TIME) Sun May 28 10:51:14 CEST 2017
After your question, I have rebuilt cppunit then podofo, but it failed again
Created attachment 475286 [details, diff] The ebuild patch needed The problem is not in rebuilding... Its the podofo ebuild that needs updating... The new dev-util/cppunit-1.14.0 requires when used, the -std=c++11 or -std=gnu++11 flags to be added in the application using it... The error is a kinda self-explanatory: ------ skip ----- from /dev/shm/portage/app-text/podofo-0.9.6_pre20170508-r1/work/podofo-0.9.6_pre20170508/test/unit/ColorTest.cpp:21: /usr/lib/gcc/x86_64-pc-linux-gnu/5.4.0/include/g++-v5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options. #error This file requires compiler and library support \ ^ In file included from /usr/include/cppunit/TestAssert.h:8:0 ------ skip ----- So since podofo already inherits flag-o-matic, what's needed is to add: append-cxxflags "-std=c++11" in src_prepare() or src_configure() stages of the ebuild.... BTW the same problem exists in media-video/dirac-1.0.2-r1
I can reproduce the problem with gcc-5.4.0, but not with gcc-6.3.0. (In reply to PhobosK from comment #5) > The new dev-util/cppunit-1.14.0 requires when used, the -std=c++11 or > -std=gnu++11 flags to be added in the application using it... Why is that necessary, when according to this news item, gcc-5 uses the new C++11 ABI by default? https://www.gentoo.org/support/news-items/2015-10-22-gcc-5-new-c++11-abi.html Anyway, I've pushed this fix which appears to suppress the problem when you don't have tests enabled: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=24598d33ad2f2c5f9c2077ad850fb7516f782bdd
So, can we declare this solved?
