Description
when using the Intel compiler with Visual Studio 2012 the checks in qcompilerdetection.h are wrong for some of the c++11 features.
initializer_list is not included with Visual Studio 2012
qcompilerdetection.h has for the intel compiler:
# if __INTEL_COMPILER >= 1300 # define Q_COMPILER_ATOMICS // constexpr support is only partial //# define Q_COMPILER_CONSTEXPR # define Q_COMPILER_INITIALIZER_LISTS # define Q_COMPILER_UNIFORM_INIT # define Q_COMPILER_NOEXCEPT # endif
the check needs to take into account what Visual Studio is being used with Intel
the Intel compiler error:
platform/ntamd64/Components/ExternalLibraries/Qt/5.5.0/include/QtCore/qflags.h(43): catastrophic error: cannot open source file "initializer_list" #include <initializer_list> ^ compilation aborted for TdrawProcess.cpp (code 4)
when using the Intel compiler, it doesn't have include files of it's own it uses those of the associated Visual Studio installation. The defines from the compiler dry run shows that Intel is version 1500, but at the same time Microsoft _MSC_VER is 1700 which would mean that Q_COMPILER_INITIALIZER_LISTS should not be defined, but it is
