Convert external to gen codebox?

    Jun 15 2013 | 12:45 pm
    So I have this external (by Alex Harker) that I've been using for mp3-ification of sound in my patch. It sounds and works awesome. But it's just an .mxo, and a 32bit one. I've been trying to convert my patch to a project to share more easily, but once it's flattened into a project, it's much harder for end users to replace individual files depending on the operating system they use. Up to now I just had windows users replace the poly~ file with a version that doesn't use the external, and they were good to go. With a maxproject, that's not an option anymore.
    I'm wondering if the external can just work inside a codebox.
    I pasted the .c inside codebox and it's not working, and throws up errors I don't understand:
    gen_domain: dsp.gen: [string "gen2.Operators"]:711: expr/codebox object missing expression gen~: failed to compile patcher
    So I'm wondering if it's a syntax thing that needs to change, or if it is more complex than that, and will require refactoring the code altogether.
    Here is the gen object with the code pasted in:
    This is how the actual external is being used.
    And here is the unedited .c file, as codebox changes it a bit:
