Unity使用IL2CPP方式打Windows包

笔者Unity版本2021.3.8f1

1,确保安装了对应版本的扩展包：UnitySetup-Windows-IL2CPP-Support-for-Editor

2,打包报错：

error: Could not set up a toolchain for Architecture x64. Make sure you have the right build tools installed for il2cpp builds. Details:
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

和

Internal build system error. BuildProgram exited with code -2146233088.
error: Could not set up a toolchain for Architecture x64. Make sure you have the right build tools installed for il2cpp builds. Details:
IL2CPP C++ code builder is unable to build C++ code. In order to build C++ code for Windows Desktop, you must have one of these installed:

Unable to detect any compatible Visual Studio installation!

这里：unable-to-build-il2cpp 建议使用Visual Studio Installer补充安装一些C++相关的工具包。

3,若依旧报错类似Building Library\Bee\artifacts\WinPlayerBuildProgram\ei6vj\ejx6_b_vm6.lump.obj failed with output: i3ib_vm6.lump.cpp
可以考虑把如下脚本放到Assets目录下(来自这里)

#if UNITY_EDITOR
using System;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
public class MsvcStdextWorkaround : IPreprocessBuildWithReport
{
    
    
    const string kWorkaroundFlag = "/D_SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS";
    public int callbackOrder => 0;
    public void OnPreprocessBuild(BuildReport report)
    {
    
    
        var clEnv = Environment.GetEnvironmentVariable("_CL_");
        if (string.IsNullOrEmpty(clEnv))
        {
    
    
            Environment.SetEnvironmentVariable("_CL_", kWorkaroundFlag);
        }
        else if (!clEnv.Contains(kWorkaroundFlag))
        {
    
    
            clEnv += " " + kWorkaroundFlag;
            Environment.SetEnvironmentVariable("_CL_", clEnv);
        }
    }
}
#endif // UNITY_EDITOR
