I’m trying to build UE 5.0 and I’m getting unresolved externals. I have no idea why this is happening.

Is no one else getting this? How is anyone building the 5.0 branch?

Hi @AlienRenders,
I suggest you try my documented build for Visual Studio 2022, This still works for 2019. VS 2022 is much faster

Visual Studio 2022 builds and runs UE5.0

Your set of instructions didn’t work. But the 5.0 branch was just updated and it now builds.
