I'll attach a part of build log (since its still compiles) some investigation: no -std=c++0x in gcc command lines in compile log this condition from ./src/3rdparty/webkit/Source/JavaScriptCore/wtf/NullPtr.h never resolves into true #if __has_feature(cxx_nullptr) || (GCC_VERSION_AT_LEAST(4, 6, 0) && defined(__GXX_EXPERIMENTAL_CXX0X__)) regardless of current active gcc profile (x86_64-pc-linux-gnu-4.6.2) and used c++0x use flag Reproducible: Always emerge --info Portage 2.2.0_alpha96 (default/linux/amd64/10.0/developer, gcc-4.6.2,

After putting nls into packages.use for all fonts it surprisingly installes without complaints. Not shure if this was the reason, I had synced too… wbr
IIRC webkit is still not 100% compatible with c++0x, perhaps that's why qt-webkit's buildsystem disables it... I haven't done any investigations though.

same problem here, without c++0x I cannot compile... after sync, gentoo masked the flag, so I cannot compile again....

Confirmed: WebCore/WebCore.pri forcefully disables c++0x... # Disable C++0x mode in WebCore for those who enabled it in their Qt's mkspec *-g++*:QMAKE_CXXFLAGS -= -std=c++0x -std=gnu++0x JavaScriptCore should still be compiled with c++0x though.
USE=c++0x has been dropped from all qt-webkit ebuilds since it was useless. Closing as UPSTREAM, because the real issue (C++11 support in webkit) must be solved there.
