LNK2019 - visual studio 2013 - error despite having defined all symbols

Question

I have a Win32 Console Application project in Visual Studio 2013. I've set up the project to work with OpenCV 2.4.9. I'm also using PGRFlyCapture SDK (http://ww2.ptgrey.com/sdk/flycap), so I have configured the paths for include,bin,lib for this sdk.

There's a header file that I've created, along with a .cpp file to define all the function prototypes declared in the header file. Despite that, I'm getting the LNK2019 unresolved external symbol error.

1. I need help getting rid of these LNK2019 errors.
2. Would like a link to the PGRFlyCapture SDK as I didn't find it, maybe I've configured the SDK with the project in Visual Studio incorrectly.

Posting the error list for reference.

Answer 1

I did a little digging around and found that WindowsSDK was not installed on my system. Installed it and linked Vfw32.lib to my project. All LNK2019 errors got resolved.
