我希望你能帮助我。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，但无法让它工作！我怀疑我的 MinGW 安装而不是 CxxTest 出了问题，但这真的很难知道 - 错误来自 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
在命令行上我运行：
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 并运行我的单元测试。在我的笔记本电脑上，我收到了数千个错误。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，它工作正常。有谁知道发生了什么？
