Building engine source. Fails on Plugin

General Feedback & Requests

When building UE5 from source I get this error.

https://pastebin.com/raw/y4U7qnhj

It seems as the plugin CADLibrary isn’t building properly.

There is this menthod HashCombine that fails because it is not given the correct number of arguments. So of course I would like to know how to fix this, but I would also like to know how I could go by disabling Plugins in the build process. I’m pretty confident that I don’t need the CADLibrary.

How I built the engine:

  • Clone git repo, branch UE5-main
  • Inside repo dir I run Setup.bat, then GenerateProjectFiles.bat
  • Inside Visual Studio 2019 I change configuration to ‘Development Editor’ and ‘Win64’ architechture.
  • Right click UE5 project and select build.
  • About 1.5 hours in the build fails.

EDIT: I looked over my Visual Studio settings and found I didn’t have the Unreal Engine build installed. So I followed this guide to be sure I didn’t miss anything Setting Up Visual Studio for Unreal Engine | Unreal Engine Documentation

Appreciate any help I can get!
Thanks

Setting up the visual studio settings didn’t fix the problem.

Hi @anonymous_user_60083892,
The git repo [ue5-main] often fails as its updated many times a day and may not be reliable at its cutting edge.

I have made available a version that compiles and works on Vs 2019 and VS 2022 Preview
Visual Studio 2022 Preview is 64 bit and compiles and runs UE 5.0 EA approximately 20% FASTER - Development Discussion / Unreal Engine 5 Early Access - Unreal Engine Forums

Ii rebuild this every new version of VS 2022 Preview
because it works with 2019 as well.

I cannot fix [ue5-main], because its Epic Staff version.

Thanks! I will try your example and let you know if it works! :slight_smile:

Solution for me at the moment was to checkout the latest released commit for Early-access. Then I manage to get further.

We’ll see if I get stuck somewhere else :slight_smile:
