Qt Creator: Treat warnings as errors

Question

在Visual Studio中，有一个选项可以告诉编译器将警告视为错误，如何使用Qt Creator设置它（我使用VS2008作为编译器）。

Answer 1

I needed to add

QMAKE_CXXFLAGS += /WX

to my .pro file.

Answer 2

For both compilers (VS and MinGW) use:

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

Answer 3

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.
