@juancarlospaco this is easily done on your own system, not in a PKGBUILD, given that building packages runs as root:

sudo groupadd unrealengine-users
sudo usermod -aG unrealengine-users (your-username)
sudo chown -R root:unrealengine-users /opt/unreal-engine
sudo chmod -R 775 /opt/unreal-engine

Permission issues like this are already mentioned on the UE Arch wiki page: https://wiki.archlinux.org/title/Unreal_Engine_4#Installing_from_the_AUR

This is a user system problem; I already did what I could without needing users to do the above by giving the 777 permissions. If it still gives you trouble, you'll have to use the example to solve it or change the install location to somewhere you have user permissions by default (as I cannot do this for you).

Will update to 5.0 when it is released.

I'd like an option to toggle using the non-official icon off (default true is fine). It just clashes, so I keep having to modify the script. A simple bool would be easier. :]

Removing xf86-video-amdgpu and adding IgnorePkg = xf86-video-amdgpu to /etc/pacman.conf and reboot fixed the problem of Vulkan for me (its known to cause problems with video/3D/Games, I dont have AMD GPU but AMD APU but still).

If you still have problems/crashes, also I added IgnorePkg = lib32-nvidia-utils libvdpau libxnvctrl nvidia nvidia-dkms nvidia-settings nvidia-utils opencl-nvidia to /etc/pacman.conf because for some reason it crashes or gets unstable if nvidia drivers change (I have to re-build UE5 if nvidia driver upgrades).

Make sure intel-vulkan is installed; your CPU does support Vulkan but either:

  • you are missing the Intel-specific Vulkan driver,

  • there's a bug in UE5's Vulkan code for handling your hardware (somehow),

  • or your specific integrated GPU in your Intel processor may not support a minimum Vulkan version required for UE5 to function (yours supports up to Vulkan 1.2, from what I've been able to gather)

@Neko-san it's just a Dell XPS 13 Laptop (so v.low spec for 3D):
- Intel(R) Core(TM) i7-1065G7 CPU @ 1.30GHz
- Intel Corporation Iris Plus Graphics G7 (rev 07)

And vulkan-icd-loader is installed.

Note: I'm currently exploring how to fix the issue via the forum: https://bbs.archlinux.org/viewtopic.php?pid=2101341#p2101341

@anthillsocial What hardware do you have? Tell me your CPU and GPU; it might be either that your hardware doesn't support Vulkan or you might not have vulkan-icd-loader and/or a Vulkan driver installed (which reminds me, I should have added that to the PKGBUILD depends; I forgot that UE uses Vulkan for its editor)

Everything has compiled and installed ok, though when starting the unreal editor I get a crash:

Fatal error: [File:./Runtime/VulkanRHI/Private/VulkanUtil.cpp] [Line: 1017]  VulkanRHI::vkCreateQueryPool(Device->GetInstanceHandle(), &PoolCreateInfo, VULKAN_CPU_ALLOCA

FIXED: Thanks @Neko-san Installing dotnet-runtime & dotnet-sdk got the install past the MSBUILD error.

Neko-san commented on 2023-05-19 21:24 (UTC)

@anthillsocial If you don't have dotnet installed, let me know; it might be that a dependency is missing and Unreal just isn't telling us. Normally, I'd run namcap on a completed archive to find out but namcap doesn't handle large packages like Unreal too well (throws errors)

If you do have dotnet installed, try setting "arch_auto" in the PKGBUILD to false; I didn't have an issue with it, but I'd like to know if this is a possible cause for your problem

anthillsocial commented on 2023-05-19 20:17 (UTC) (edited on 2023-05-20 07:58 (UTC) by anthillsocial)

I'm getting the "Running AutomationTool..." and "Setting up bundled DotNet SDK" build message errors: 

MSBUILD : error MSB4166: Child node "2" exited prematurely. Shutting down.

RunUAT ERROR: AutomationTool failed to compile.
==> ERROR: A failure occurred in build().
Aborting...
:: Unable to build unreal-engine - makepkg exited with code: 4

Any tips?

sticklebrix commented on 2023-05-12 02:03 (UTC)

@greenhandzdl I tried running makepkg in the build directory, and it looks like the PKGBUILD uses 5.2-release rather than 5.2 as the branch to retrieve from. Modifying the PKGBUILD locally to use 5.2 should work.
