我正在尝试更新我们的基于ARToolkit5的Unity应用程序，这个应用已经在Google商店里运行了多年。ARToolkit5不再受支持，但我们仍然依赖于大约4年前构建的它的库。我的统一版本是2020.1.11f1。

我需要升级到，并增加64位支持。因此，我理解，第一步是将Mono改为IL2CPP作为脚本后端。这个32位的Android ARMv7应用程序是在Mono中构建的，运行良好，但当我只做了一个更改，即将IL2CPP作为Project下的脚本后端时，构建就失败了。我甚至还没有尝试添加ARM64选项。

当使用IL2CPP时，生成失败的BuilderFailedException和数百个Undefined References.

我认为这说明了链接器找不到列出的函数的定义，这些函数都来自于一个ARToolkit库：libARWrapper.so

这个库存在于位于：Assets/Plugins/Android/lib/armeabi-v7a/libARWrapper.so的Unity中。

团结检查器中的快速检查表明，库导入设置似乎是正确的。

​

​

这似乎表明这个库将包含在安卓ARMv7构建中，这就是。我知道库在ARMv7设备上工作和运行，并且使用Mono构建，所以我认为它只是被排除在IL2CPP构建之外。

因此，总之，Mono在其构建中包含了libARWrapper.so库，但是当我切换到IL2CPP进行完全相同的项目时，这个库就不包括在内了，因此无法链接。有人知道为什么会这样吗？谢谢!

苏尼乌斯的答案适用于安卓，但它破坏了我的WebGL构建，抛出了运行时错误“要使用dlopen，您需要使用WebGL的链接支持”。

我用条件编译修正了这个问题。例如，从最初的海报肉汁

代码语言：javascript
运行
复制
#if UNITY_WEBGL
    [DllImport("__Internal")]
    public static extern void arwSetLogLevel(int logLevel);
#else
    [DllImport("scrBrowserScripting.jslib")]
    public static extern void arwSetLogLevel(int logLevel);
#endif

希望这能节省一些人的时间：)
