c++ - 无法在 VS2015 中正确链接 Google Protobuf

Question

我花了几天时间尝试获取 C++ 应用程序，但我陷入了库/dll 进程，我对这两个应用程序有问题。

我下载了 protobuf 3.0.0 的 C++ 版本，制作了 .lib 和 .dll(以测试它们两个)，我使用它来获取 .sln

cmake -Dprotobuf_BUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX="../install" ../cmake

它给了我一个解决方案，我用 vs2015 打开并编译进行调试，然后编译文件，然后使用提供的 .bat 生成包含文件。

所以，当我转到 VS2015 并尝试使用链接的 .lib 进行编译时，它给了我这个错误

1>libprotobufd.lib(dynamic_message.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj

我确信我在库构建中运行应用程序作为调试，并且游戏也作为调试运行。

此外，我尝试了 .dll(删除库和引用)，在 main.cpp 文件的顶部写入“#define PROTOBUF_USE_DLLS”，并且出现了很多这样的链接器错误

我有点迷失和卡住了，所以如果有人可以帮助我重定向我必须搜索的位置，我将不胜感激。

感谢您的宝贵时间

Answer 1

由于我无法发表评论，因此将其作为答案发布。 如果我正确理解了你的项目的结构，这个东西:

`1>libprotobufd.lib(dynamic_message.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj`

告诉您，您尝试链接的库的运行时库设置与您的项目不匹配。 检查项目属性 -> C/C++ -> 代码生成 -> 运行时库并确保两个项目的此设置相同。

附注在 vs2015 update 3 中链接包含原始文件的静态库也有问题，但似乎你的情况有所不同..
