c – 我需要链接哪些库来构建googlemock示例？

概述我能够在VS2010中编译googlemock v1.6.x并生成发布和调试库.换句话说,我遇到的问题不是这个 GoogleMock and GoogleTest in Visual Studio 2010 现在我正在关注这里的例子http://code.google.com/p/googlemock/wiki/ForDummies,我遇到了这些错误.我确实链接了生成的* .lib文件,并在VS2 我能够在VS2010中编译Googlemock v1.6.x并生成发布和调试库.换句话说,我遇到的问题不是这个 GoogleMock and GoogleTest in Visual Studio 2010

现在我正在关注这里的例子http://code.google.com/p/googlemock/wiki/ForDummies,我遇到了这些错误.我确实链接了生成的* .lib文件,并在VS2010中添加了正确的库目录.那我还需要链接什么呢？

解决方法 这看起来你在选择C Runtime和C标准库时遇到了不匹配.

您可以使用编译器开关/ MT,/ MTd,/ MD或/ MDd在这些版本的静态(.lib)或共享(DLL)版本之间进行选择. MT变体表示静态库,MD表示共享.附录d表示每个的调试版本.

这些可以通过转到Project =>在Visual Studio中设置.属性=>配置属性=> C/C++ =>代码生成=>运行时库

问题似乎是您的项目使用/ MD和/ MDd,但GMock和Gtest是使用/ MT和/ MTd构建的.您需要使用/ MD和/ MDd标志重新编译GMock / Gtest,或将您的更改为/ MT和/ MTd.
