Build unreal 5.1.1 from source on Mac Sonoma M3 Pro

Development Getting Started & Setup
,
1

Hello people,

I am a newbie here. My goal is to build UnrealEngine 5.1.1 using source on Macbool Pro M3 running Sonoma :-

  1. When I tried to run the setup.command file it gave me dotnet sdk missing error, I installed the required dotnet version but no luck. I then copied the Dotnet folder from the unreal engine that I installed via binary and than reran the setup.command and it worked fun.
  2. Now the next step to generate the project files fails with following error. Note I have latest Xcode 15.0.1.
