将 Unity 2017.4.34f1 (LTS)与IL2CPP与NDK r13b 一起使用，我尝试将我的 Unity 项目导出到 Android 项目（构建过程）。

注意：我使用 IL2CPP 是因为 Google PlayStore 需要 32 位和 64 位，所以我不能再使用Mono作为脚本后端。

但是，它失败了，我收到以下错误：

我正在尝试更新我们基于 ARToolkit5 的 Unity Android 应用程序，该应用程序已在 Google Play 商店中存在多年。ARToolkit5 不再受支持，但我们仍然依赖它大约 4 年前构建的库。我的Unity版本是2020.1.11f1。

我需要将应用程序升级到 Google App Bundle 并添加 64 位支持。因此，据我了解，第一步是从 Mono 更改为 IL2CPP 作为脚本后端。32 位 Android ARMv7 应用程序在 Mono 中构建并运行良好，但当我实际上只进行一项更改（即在项目设置下切换为 IL2CPP 作为脚本后端）时，构建失败。我什至还没有尝试添加 ARM64 选项。

使用 IL2CPP 时，构建失败并BuilderFailedException显示数百个Undefined References...

总是卡在IL2CPP超过10分钟。为什么以及如何加快这一过程？我尝试过找到的示例，例如导出到同一文件夹。

这个问题专门针对 Unity3d IL2CPP 和 iOS。

使用反射调用泛型方法

class SourceValue<T> { public T value; }
class TargetValue<T> { public T value; }

static TargetValue<T> GenericMethod<T> (SourceValue<T> source) {
    return new TargetValue<T> { value = source.value };
}

void Main () {
    Type genericType = typeof(SourceValue<float>);
    Type typeArg = genericType.GenericTypeArguments[0];
    MethodInfo mi = GetType ().GetMethod ("GenericMethod", Flags | BindingFlags.Static);
    MethodInfo gmi = mi.MakeGenericMethod (typeArg);
    object src = new SourceValue<float> { value = 0.5f };
    object trg = gmi.Invoke (this, new object[] { src …

IL2CPP.exe是一个 Unity 实用程序，用于将 C# IL 代码转换为 C++。我的问题是：这个可执行文件是否可以在Unity 游戏开发环境之外用作通用工具，用于将任何.NET 应用程序（不仅仅是游戏）转换为高性能本机可执行文件？

虽然我确实懂一些C++，但如果能够用我熟悉且流利的语言 (C#)编写各种程序，那就太好了……无论是音频/视频/音乐制作 DAW 还是操作系统级安全/取证工具或机器学习平台或任何其他资源密集型......并且知道它们将像直接用 C++ 编写的应用程序一样高效运行。

我需要将2017.2至2017.3的项目表格更新为新的Vuforia版本(因为新的模型目标).播放器仍然可以正常工作.但是,如果我想为Hololens建立一个UWP应用程序.我收到错误,脚本后端不正确(使用IL2CPP).

Vuforia currently does not support the IL2CPP scripting backend for Windows Store Apps. Please select ".NET" as the scripting backend in the "Other Settings" section of the Player Settings

 UnityEngine.Debug:LogError(Object)
 BuildObserver:OnPreprocessBuild(BuildTarget, String)
 UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

所以我在"设置"中更改为.NET.但现在错误是,IL2CPP构建了修补程序.

UnityException: Build path contains project built with IL2CPP scripting backend, while current project is using .NET scripting backend.

那我现在该怎么办？我能改变一下吗？

这些是我原来的设置:
