在Qt Creator中禁用-Wmissing-field-initializers警告 [英] Disable -Wmissing-field-initializers warning in Qt Creator

问题描述

如何在Qt Creator中禁用 -Wmissing-field-initializers 警告?

How do I disable the -Wmissing-field-initializers warning in Qt Creator?

我有一个Qt Creator/MinGW项目，当我对结构进行零初始化时:

I have a Qt Creator/MinGW project, and when I zero-initialize a struct:

void test() {
    struct foo {int a, b;};
    foo a = {};
}

我收到此警告:

test.cpp:12: warning: missing initializer for member 'test()::foo::b' [-Wmissing-field-initializers]
         foo a = {};
                  ^

我尝试过:

QMAKE_CXXFLAGS += -Wnomissing-field-initializers

但是没有这样的选择. QMAKE_CXXFLAGS-= -Wmissing-field-initializers 也不起作用.

But there was no such option. QMAKE_CXXFLAGS -= -Wmissing-field-initializers didn't work, either.

实际上，没有在命令行中明确指定 -Wmissing-field-initializers .这是编译器的命令行:

The -Wmissing-field-initializers is not explicitly specified in the command line, actually. This is the compiler's command line:

g++ -c -pipe -fno-keep-inline-dllexport -g -frtti -Wall -Wextra -fexceptions -mthreads -DUNICODE -DSRCDIR=\"C:/Workspace/NewProjects/TreTest/\" -DQT_TESTLIB_LIB -DQT_CORE_LIB -DQT_TESTCASE_BUILDDIR=\"C:/Workspace/NewProjects/build-TreTest-Desktop_Qt_5_4_2_MinGW_32bit-Debug\" -I"..\TreTest" -I"." -I"..\..\..\Qt\5.4\mingw491_32\include" -I"..\..\..\Qt\5.4\mingw491_32\include\QtTest" -I"..\..\..\Qt\5.4\mingw491_32\include\QtCore" -I"debug" -I"..\..\..\Qt\5.4\mingw491_32\mkspecs\win32-g++"  -o debug\fuzzyregex.o ..\TreTest\fuzzyregex.cpp

推荐答案

结果是我忘记添加破折号.这可行:

Turns out I had forgotten to add a dash. This worked:

QMAKE_CXXFLAGS += -Wno-missing-field-initializers

我一直在尝试 -Wnomissing-field-initializers (不带破折号)，这就是为什么我收到一个错误消息，指出没有这样的参数.

I had been trying -Wnomissing-field-initializers (without dash), that's why I was getting an error that there is no such parameter.
