Description
Hi All,
QTCreator latest code (master 872660f) failed to build with /std:c++latest on MSVC. Can you help look at this issue? Thanks!
BTW, We also used several options to disable some c++20 behaviors to unblock the build, do you have plan to fix them? I can provide build logs.
Build steps:
- git clone git://code.qt.io/qt-creator/qt-creator qt-creator
- cd qt-creator
- set CL=/D_HAS_AUTO_PTR_ETC=1 /D_HAS_DEPRECATED_RESULT_OF=1 /D_SILENCE_CXX17_RESULT_OF_DEPRECATION_WARNING /D_HAS_DEPRECATED_UNCAUGHT_EXCEPTION=1 /D_SILENCE_CXX17_UNCAUGHT_EXCEPTION_DEPRECATION_WARNING /std:c++latest /permissive /Zc:rewrittenExpressions-
