带有MSVC2015的QT触发多个编译错误

Question

Trying to update our project from Qt5.6 on MSVC2013 to Qt5.6 on MSVC2015, I got an endless list of error:

• C2059
• C2143
• C2447
• C2059

All of them seem related to lines of type:

Q_DECLARE_SHARED( WhateverHere )

We make a new install on several machines and all of them has the same issue.

The question is: What is the reason of those errors? What is the solution to this issue?

Answer 1

EDITED:

After some further research, it seem that I had some compatibility code like:

#ifdef _MSVC_DEV
#define noexcept throw() //not exactly the same
#endif

As MSVC2015 include now noexcept , this macro become invalid. Instead of showing a correct error there, this trigger some strange state in the compiler which then throw errors in Qt code.
