MinGW / CxxTest 奇怪的错误

MinGW / CxxTest bizarre errors

希望你能帮助我。我在我的主要开发机器上使用 CxxTest 编写了一个小项目。在这台机器上一切正常,没有问题。但是,我尝试在我全新的笔记本电脑上设置这个项目,但无法正常工作!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 - 错误源自 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

在命令行我运行:

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

这会生成 runner.cpp。现在我运行:

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

这通常工作正常,输出 runner.exe 和 运行ning 我的单元测试。在我的笔记本电脑上,我收到了数千个错误。下面是前几个:

当我在一个简单的 hello world 文件上 运行 g++ 时,它工作正常。有谁知道是怎么回事吗?

我最近也将 MinGW 和 运行 更新为非常相似的问题。经过一些研究,我发现 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。希望对您有所帮助!

如果您使用的是 CMake,请确保您有

set( CMAKE_CXX_EXTENSIONS ON )

在您的 CMakeLists.txt 文件中
