Error while building Unreal 5

Development Programming & Scripting
,
1

I’d love some help. I’m attempting to install Unreal Engine 5 using the github method.
I am unable to download and use the Epic Installer, as my Mac is no longer supported.
System specs also show that I can’t get a newer version anyways, so I went back to 5.0

I’ll include my system specs and software version specs below.
Maybe I am missing something simple, which is fine. If I can’t run this, I’ll just try something else.

First, this what I’ve done, and where I am stuck:

Got the Zip file.
Ran the Setup.Command
Ran the SetupProjectFiles.Command
After that, opened the UE5 Workspace file that was created.
Set to use ‘New Build System’.
Now trying to build in XCode using the *ShaderCompileWorker.

I get this build error…

Setting up bundled DotNet SDK

/UnrealEngine-5.0.0-release/Engine/Build/BatchFiles/Mac/XcodeBuild.sh: line 15: dotnet: command not found

Failed to build the build tool (UnrealBuildTool)

Command /Users/Ben/Downloads/UnrealEngine-5.0.0-release/Engine/Build/BatchFiles/Mac/XcodeBuild.sh failed with exit code 1

Everything I’ve tried:

  • restarting my computer.
  • using legacy build in XCode
  • Cleaning the build file(s)
  • emptying DerivedData folder
  • using a different SDK (like version 6, 8 etc)
  • setting up paths for SDK, although may have done this wrong.

Referencing the SDKs in the UE files, it appears to seek the 3.1.32 runtime app.
I got the .NET core 3.1 (3.1.32 is the last version in that set) from MS.
It uses the 3.1.32 runtime, and 3.1.426 SDK, which I have installed.

Here are the specs, please be kind:

Mac Os 11.7.1,
Macbook Pro mid 2014
2.5 GHz Quad-Core Intel Core i7
16 GB 1600 MHz DDR3
NVIDIA GeForce GT 750M 2 GB

XCode: Version 13.2.1 (13C100)

Unreal Engine attempting to install: 5.0.0

Netcore runtime 3.1.32
Net SDK 3.1.426

Visual Studio Community 2017

Install dotnet core, I think you can install it from homebrew or download from the official website, but make sure it’s available in your PATH, which you can check using which dotnet command in terminal.

HI @Mr.Booksy ,Welcome to the forums!
I don’t have much experience with macOS, as I don’t use that operating system. However, I’m sharing this documentation, which explains the step-by-step process to install Unreal Engine 5 from GitHub.

Hope it helps!

‘but make sure it’s available in your PATH, which you can check using which dotnet command in terminal.’

This is the part I’m unsure about… I have net core, which I listed in the post. I have done the path commands but I didn’t get the build to work. Maybe I’m not doing it in the correct way. Everything was installed in the standard file locations, so it should be able to access them.

I’m just going to move back down to versions of Unreal 4 for now. It’s too close to top specs on my current build, and I’m barely able to handle 5 anyways. Going to save for a better computer.
