I tried compiling/building the google test samples but I decided to try something simplifier instead when I couldn't get the samples to work. I found this video that details how to set up the unit tests and run them using google test (but from the command line instead): http://vimeo.com/53690756

However, assuming the source code is correctly implemented and I went to my project's properties and set the C/C++'s Additional Include Directories to the g-test-1.6.0 include directory and the Linker's Additional library directories to the same g-test-1.6.0 include directory. However, Linker > Input > Additional Dependencies, I wrote gtestd.lib.

The only error I get is 101 error LNK1103: cannot open file 'gtestd.lib', I guess what I didn't get from the video is how they generated that static library file? When I ran the build using debug previously on another project, I was able to get a gtestd.lib file under Debug and I tried to include that file under the g-test-1.6.0 include directory but then I got 65 linker errors instead.

Essentially, what I'm asking is how to set up google test in Visual Studio 2010 without getting a library or linker error? Where do I get the proper version of gtest.lib or gtestd.lib and where should I place that library file so it's found?

Here are a few of the linker errors I'm receiving:

错误告诉你问题所在。它找不到 gtest.lib。我刚刚提供了一个SSCCE来证明这确实有效。首先阅读gtest 文档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 不支持与可变参数有关的东西？我使用了这个解决方案，并将在此处概述它，而不是通过链接提供答案。

第 1 步：下载gtest 1.6

第 2 步：解压到目录 DIR。

第 3 步：导航到 DIR/msvc

第 4 步：双击 gtest-md.sln 并根据需要进行迁移。你会收到一些警告。

第 5 步：对于解决方案中的每个项目，右键单击并将其添加到 C/C++ 中的预处理器定义中。_VARIADIC_MAX=10

第 6 步：构建解决方案。

第 7 步：导航DIR/msvc/gtest-md/Debug/ 到此文件夹具有 gtestd.lib 以及 gtest-main-mdd.lib 文件。我把它的全部内容Debug粘贴到一个新文件夹DIR/lib中。

第 8 步：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 附加DIR/Include包含库和DIR/lib附加库依赖项下的添加。

第 10 步：转到Linker->Input并在附加依赖项下添加gtestd.lib.

第 11 步：转到C/C++->Preprocessor并在预处理器定义下添加_VARIADIC_MAX=10

第 12 步：在源代码中添加

#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，则需要考虑是否错误地创建了 .lib 或没有将 msvc 指向库的正确目录。

我最近为 Visual Studio 2010 构建了 gtest1.6，并在遇到您报告的类似错误后让它工作。

我希望我能更好地跟踪我为修复它所做的工作，但我很确定它只是将 C/C++ -> 代码生成 -> 运行时库设置为 /MT 用于 gtest 项目（gtest 和 gtest_main）和我自己的测试项目。请参阅此链接。

我没有改变任何与可变参数有关的东西。
