MinGW / CxxTest奇怪的错误

Question

我希望你能帮助我。我已经在我的主开发机器上使用CxxTest写了一个小项目。在这台机器上，一切都运行得很好，没有问题。然而，我试着在我的全新笔记本电脑上设置这个项目，但就是不能让它工作！我怀疑是我的MinGW安装出了问题，而不是CxxTest，但这真的很难知道--错误源于CxxTest文件。这是项目的文件夹结构：

lib/
    cxxtest-4.3/
src/
    TestUtils.h
    test.cpp
test/
    MyTestSuite.h
    libstdc++-6.dll

在命令行上，我运行：

cd test
..\lib\cxxtest-4.3\bin\cxxtestgen --error-printer -o runner.cpp MyTestSuite.h

这将生成runner.cpp。现在我运行：

g++ -o runner.exe runner.cpp -I "../lib/cxxtest-4.3" -std=c++11

这通常工作得很好，输出runner.exe并运行我的单元测试。在我的笔记本电脑上，我得到了成千上万的错误。这里只看一下前几个：

当我在一个简单的hello world文件上运行g++时，它工作得很好。有人知道这是怎么回事吗？

Answer 1

我最近也更新了MinGW，遇到了非常非常类似的问题。经过一些研究，我找到了this question on SO，并尝试用-std=gnu++11替换-std=c++11。这为我解决了这个问题。希望这能有所帮助！

如果您使用的是CMake，请确保您有

set( CMAKE_CXX_EXTENSIONS ON )

在CMakeLists.txt文件中
