Packaging game server fails using Unreal Engine source build

Development Programming & Scripting C++

I’m attempting to package the server version of the Unreal Shooter Game for UE 4.24.3 Win64, and am getting some strange errors relating to HoloLens (which I wasn’t even aware I was linking against).

My packaging log looks like this:

I’m a bit confused because I used to be able to run the packaging process fine, so something must have gone wrong on my system somewhere in the meantime. Is there anything that might be causing these issues?

In case it helps anyone, it seems the problem was that my Windows 10 SDK installation had broken. I reinstalled the SDK from Windows SDK archive - Windows app development and that fixed things.

Confirm here as well on VS2022
Changed Win sdk from 10.0.19 to 10.0.18 and everything become fine
Also you can do it via Visual Studio Installer

I swapped the windows sdk in VS2022 and i am still getting the exact same problem on building AutomationTool

I am as well. Did you ever find a fix?

What fixed it for me is, in VIsual Studio, Solution Explorer, right click and Add Reference… on Programs->Automation->HoloLens.Automation->References:
image
and in the Browse section, which was initially an empty list, click on browse:

image
image790×542 9.78 KB

and locate the Windows.winmd file from the desired Windows SDK.
image
image945×530 15.7 KB

Note - You will need to change the file type to All Files, and by default installation they are usually located in C:\Program Files (x86)\Windows Kits\10\UnionMetadata\10.0.20348.0 or similar folder.

Hope this helps :slight_smile:

Hats off to you, I hadn’t a clue how to go about troubleshooting this one
