WebGL Error - To use dlopen, you need to use Emscripten's linking support

    Hello,

    I'm trying to make an 3d model viewer in Unity.
    1. It's WebGL.
    2. It must be in runtime.
    3. For begging my target is Obj and FBX.

    Problem:
    I found some code for it, made some improvements and it worked on Windows, standalone.

    On WebGL i get error:

    An error occured running the Unity content on this page. See your browser JavaScript console for more info. The error was:
    uncaught exception: abort("To use dlopen, you need to use Emscripten's linking support, see https://github.com/kripken/emscripten/wiki/Linking") at jsStackTrace
    ...
    ...
    If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.


    I thing this is from multi-threading.

    My questions:
    1. What is "Emscripten's linking support" about?
    2. How can i avoid this error?
    I really don't want to rewrite whole .dll for this.

    I searched on Google, but most of questions about my problem are ignored and stay with no answer for long time.

    Best regards,
    Homeak

    I doubt the questions are ignored. People just may not know. I've never even heard of whatever you're trying to use. WebGL has come a long ways, but it still has some limitations. It's very possible whatever you're trying to use (Emscripten's linking support) just isn't compatible with Unity's WebGL.

    I did poke around that link, but I don't really have time to understand it's purpose. Sorry I can't really be of much help. You might try the webgl subforums https://forum.unity.com/forums/webgl.84/
