LNK2019 - visual studio 2013 - 尽管定义了所有符号，但仍然出错

Question

我在Visual Studio 2013中有一个Win32控制台应用程序项目。我已经设置了项目以使用OpenCV 2.4.9。我也使用PGRFlyCapture SDK（http://ww2.ptgrey.com/sdk/flycap），所以我为这个sdk配置了include，bin，lib的路径。

有一个我创建的头文件，以及一个.cpp文件来定义头文件中声明的所有函数原型。尽管如此，我得到了LNK2019未解决的外部符号错误。

1. 我需要帮助摆脱这些LNK2019错误。
2. 想要一个到PGRFlyCapture SDK的链接，因为我没有找到它，也许我错误地用Visual Studio中的项目配置了SDK。

发布错误列表以供参考。

Answer 1

我做了一个小挖四周，发现WindowsSDK是不是我的系统上安装。安装它并将Vfw32.lib链接到我的项目。所有的LNK2019错误都得到了解决。
