Description Arfrever Frehtes Taifersar Arahesis 2017-05-17 08:49:08 UTC 
dev-qt/qtcore-5.7.1-r3:5[icu] with GCC <6 fails to build with ICU >=59.
Usage of C++ API of ICU >=59 requires usage of C++ >=2011.
C++ 1998 is default in GCC <6.
C++ 2014 is default in GCC 6 and 7.
Build system adds -std=c++11 to CXXFLAGS, but too late, and this flag is not passed to compiler during checks of availability of various features and libraries in src_configure() phase.
Ebuild should add -std=c++11 to CXXFLAGS.
(dev-qt/qtcore-5.9.9999:5 is not affected.)

Similar issue affects dev-qt/qtcore-4.8.x except on all compilers.

Additionally also affects qtwebkit identically as respective qt versions.
