我尝试编译/构建谷歌测试样本，但是当我无法使样本工作时，我决定尝试使用简化器。我发现这个视频详细介绍了如何设置单元测试并使用google测试运行它们（但是从命令行开始）：http://vimeo.com/53690756
但是，假设源代码正确实现并且我转到我的项目属性并将C / C ++的附加包含目录设置为g-test-1.6.0包含目录，并将链接器的附加库目录设置为相同的g- test-1.6.0包含目录。但是，Linker＆gt;输入＆gt;额外的依赖关系，我写了gtestd.lib。
我得到的唯一错误是101错误LNK1103：无法打开文件'gtestd.lib'，我想我从视频中得到的是他们如何生成那个静态库文件？当我在之前的另一个项目中使用调试运行构建时，我能够在Debug下获得一个gtestd.lib文件，并且我试图将该文件包含在g-test-1.6.0 include目录下，但后来我得到了65个链接器错误。
基本上，我要问的是如何在Visual Studio 2010中设置谷歌测试而不会出现库或链接器错误？我在哪里可以获得正确版本的gtest.lib或gtestd.lib，我应该在哪里放置该库文件以便找到它？
以下是我收到的一些链接器错误：

错误告诉您问题所在。它找不到gtest.lib。我刚刚提供了SSCCE来证明这确实有效。首先阅读gtest documentation并注意您需要从源代码构建库。这样做时，在使用MSVC时，您会遇到错误，因为MSVC不支持与variadics有关的事情？我使用了this solution，并在此处概述了不通过链接提供答案的精神。
第1步：下载gtest 1.6
第2步：提取到目录，DIR。
第3步：导航至DIR / msvc
步骤4：双击gtest-md.sln并根据需要进行迁移。你会得到一些警告。
步骤5：对于解决方案中的每个项目，右键单击并将其添加到C / C ++中的预处理器定义。 _VARIADIC_MAX=10
第6步：构建解决方案。
步骤7：导航到DIR/msvc/gtest-md/Debug/此文件夹包含gtestd.lib以及gtest-main-mdd.lib文件。我将Debug的全部内容粘贴到新文件夹DIR/lib中。
步骤8：创建一个新的空白溶胶和一个新的空白项目。添加一个新的空白.cpp。
第9步：转到Project->Properties->vc++ directories在其他包含库下添加DIR/Include，在其他库依赖项下添加DIR/lib。
步骤10：转到Linker->Input并在其他依赖项下添加gtestd.lib。
步骤11：转到C/C++->Preprocessor并在预处理器定义下添加_VARIADIC_MAX=10
第12步：在源添加
#include <gtest/gtest.h> //Or wherever your header file seems to be
int main() {
return 0;
}
这就是我所做的，我为这个库创建了一个SSCCE。如果不是，那么您需要考虑是否错误地创建了.lib，或者没有将msvc指向库的正确目录。
答案 1 :(得分：3)
我最近为Visual Studio 2010构建了gtest1.6，并在遇到类似的错误后让它工作。
我希望我能更好地跟踪我的修复方法，但我很确定它只是设置C / C ++ - ＆gt;代码生成 - ＆gt;运行时库到/ MT用于gtest项目（gtest和gtest_main）和我自己的测试项目。请参阅此link。
我没有改变任何与变量的关系。
