Qt Creator: Treat warnings as errors

Question

In Visual Studio there is an option to tell the compiler to treat warnings as errors, how do I set that using Qt Creator (I'm using VS2008 as the compiler).

[this question](http://stackoverflow.com/q/6614049/2513200) may contain hints. — Hulk, Nov 28 '13 at 13:27
@Hulk Thanks, but it doesn't say how to enable warnings as errors, only how to specify additional compiler options. — sashoalm, Nov 28 '13 at 14:07
Well if you can add compiler options I assume this one will help: http://msdn.microsoft.com/en-us/library/thxezb7y%28v=vs.90%29.aspx — drescherjm, Nov 28 '13 at 14:10
In case anyone else stumbled across this question when a project was failing to compile but not displaying any actual compile errors and just warnings, there's a good chance one of your pre-build or post-build actions is failing. — kayleeFrye_onDeck, Apr 12 '18 at 23:34

For both compilers (VS and MinGW) use:

win32-g++ {
   QMAKE_CXXFLAGS += -Werror
}
win32-msvc*{
   QMAKE_CXXFLAGS += /WX
}

An alternative to adding "QMAKE_CXXFLAGS+=-Werror" to your .pro file is to add it to build configuration via the "Projects" tab.

This setting will be stored in .pro.user file.

I needed to add

QMAKE_CXXFLAGS += /WX

to my .pro file.
