Description
QtCreator(master branch) with std:c++17 failed due to error C2668, it should be source issue, which involved by QTCreator revision http://code.qt.io/cgit/qt-creator/qt-creator.git/commit/src/plugins/nim?id=522492d85d4ef1db119b4fbfa5d33f9166e7a206,
Gcc and Clang both reject the code, one possible fix is to remove the second overload if /std:c++17 is used.
Here is the steps that I used to build QTCreator:
1. git clone git://code.qt.io/qt-creator/qt-creator.git D:\QTCreator\src
2. Open a VS 2017 x86 command prompt and browse to D:\QTCreator\src
3. set _CL_=/D_HAS_AUTO_PTR_ETC=1 /std:c++l7
4. qmake -r qtcreator.pro
5. jom
