    Linking error. VC++ 2008.

    I am working on a wrapper for an already existent ResourceManager. I don't know why it isn't working. I get no errors if I have the code in the class definition(inline), but when I changed it to an imp file. I get the following.
    Code:

    These error's don't make sense to me. I was hoping someone here could give some insight to my problem. Thank you.

    ResourceMgr is a wrapper for the already defined hgeResourceMgr. (Mainly to provide a debug-like code)

    So you made hgeResource into an import library? Did you add hgeResource.lib to your project?

    Yea, I think there may be something missing in the library file. I had to build the source for hgeResource with my project to get it to work.

    the GetSprite, GetAnimation, etc worked fine, but the others didn't. Oh well. Just more code to manage now.

    >I had to build the source for hgeResource with my project to get it to work.
    And I assume when you built it, it created a .lib and .dll. You would think adding the lib to your project would do the trick. I've never used Visual Studio, so I don't know.

    No I built the source into my project so that I don't need the library files.
