Hi 

I am using code composer studio and use Library threshold function in Video preview example. When I Build the project then it gives me following error:-

    >>   error: symbol referencing errors - './Debug/video_preview.out' not built

    In general this means that somewhere in your code you referenced a symbol as an extern (i.e. something that will exist in the end executable but is not in the C file it is being referenced from) and when the linker went to link the various object files in your project into a single executable together it was unable to locate that particular symbol. In this case it is saying that you tried to use _img in video_preview.obj (the compiled version of video_preview.c), but the symbol _img was not found in any object file you are currently linking in.

    This being said, to fix such a problem you either need to not reference the missing symbol (such as if there was a typo in your extern statement in the C file or header file), or to add the appropriate library or C file to your project which contains the definition of the symbol (such as if you were not linking in imglib.lib properly).
