P3: Somewhat important Description
When using clang with -stdlib=libc++ option, QtScript fails to build.
These lines are added to macx-clang/qmake.conf:
QMAKE_CXXFLAGS += -stdlib=libc++ QMAKE_LFLAGS += -stdlib=libc++
Command to configure:
./configure -developer-build -opensource -confirm-license -nomake examples -nomake tests -no-c++11
Build error in QtScript:
