Linking to opencv issue.

[infinityplusb]

Hi

Out of my programming depth, but trying. :)

I tried using this library before to link to OpenCV but haven't had time to look at it in a while (a year maybe).
Just trying to back into it, and my code is giving me the below warnings

LInking source files for stl_vector.h and mat.hpp are the token gestures I can take to make someone's life easier if they want to help me!

I'm not even sure what information I need to provide to help someone assist me. :(
