我在 Visual Studio 2013 中有一个 Win32 控制台应用程序项目。我已将该项目设置为与 OpenCV 2.4.9 一起使用。我还使用 PGRFlyCapture SDK ( http://ww2.ptgrey.com/sdk/flycap )，因此我为此 sdk 配置了 include、bin、lib 的路径。
我创建了一个头文件，以及一个 .cpp 文件来定义头文件中声明的所有函数原型(prototype)。尽管如此，我还是收到了 LNK2019 无法解析的外部符号错误。
- 我需要帮助来消除这些 LNK2019 错误。
- 想要 PGRFlyCapture SDK 的链接，因为我没有找到它，也许我在 Visual Studio 中错误地使用项目配置了 SDK。
发布错误列表以供引用。

最佳答案
我做了一些挖掘，发现我的系统上没有安装 WindowsSDK。安装它并将 Vfw32.lib 链接到我的项目。所有 LNK2019 错误均已解决。
关于visual-c++ - LNK2019 - Visual Studio 2013 - 尽管定义了所有符号仍出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26006413/
