[Interest] Deployment Target for Qt-5.6.2 Built at Mac-OS-10.12 with C++-11

[Robert Iakobashvili]

Hi,
Configuring Qt-5.6.2 at the recent Mac 10.12
with C++-11 built versus SDK-12 as:

./configure -opensource -debug-and-release -c++std c++11 -qt-zlib
-qt-libpng -qt-libjpeg \
-system-proxies -nomake tests -nomake examples -skip qtxmlpatterns -skip qt3d \
-skip qtactiveqt -skip qtcanvas3d -skip qtconnectivity -skip
qtdeclarative -skip qtlocation -skip qtscript \
-skip qtsensors -skip qtserialport -skip qtwebchannel -skip
qtquickcontrols -skip qttranslations -skip qtenginio -skip
qtwebsockets \
-skip qtwebengine -skip multimedia -no-sql-sqlite \
-no-openssl -securetransport

it builds and works properly,
but it is using the new C++ library libc++

clang -v
Apple LLVM version 8.0.0 (clang-800.0.38)

When trying -no-c++11 flag, Qt was using the old C++ library libstdc++,
but clang was warning about its deprecation and suggesting to use
the new C++ library "available since 10.9 target".

Qt in its turn sets 10.7 as the minimal deployment target.

The question is at which minimal deployment target it will work?
10.7?
10.8?
10.9?

Thank you.

Kind regards,
Robert
