I have some code in Linux that uses exiv2 to read the metadata of a folder full of photos, depending on requirements it can reconstruct missing metadata, and stamp a logo as well as lat/long onto the photos. I'm trying to port it into windows visual studio so that I can make a GUI and let other people use it.
I downloaded the MSVS source code for exiv2, I've added the include folder and lib folders both in the include line and the linker line in the project properties dialogue. When I try to compile I get an undefined reference error whenever an EXIV2 object is called.
I'm guessing I have some sort of linking or library building issue. I built it on linux using g++ and had no problems. If I weren't trying to make a GUI I'd probably just get a windows version of g++ to compile with.
This is one of the error messages I'm getting.

I've tried adding include files for both the "include" and the "lib" folders to both the include line and to the linker. I also tried to compile the sample program that came with Exiv2, and I get the same error,so I'm guessing it's a VS setting issue.
So, the way to do this is as follow:
In "Properties" … "C/C++" … "General" … "Additional Include Directories", add the include and lib folders, and do the same in "Linker" … "Additional Library Directories".
Finally, in "Linker" … "Command Line" … "Additional Options", write in "exiv2.lib".
