@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.

@zerophase

You're on Arch

yep

and just run makepkg -sric

yeah, I also thinking about installing ue4 without pacman

opening unreal

with -vulkan flag, with -opengl works fine

vulkan-icd-loader and vulkan-radeon are installed, vc: HD 7950

@moadib yeah thanks mate =) I guess maybe I need some kernel tweaks ¯_(ツ)_/¯

moadib commented on 2018-11-10 05:12 (UTC)

@ruestique try to launch with -opengl4 parameter, from 4.21 unreal engnine uses Vulkan renderer by default

zerophase commented on 2018-11-10 04:59 (UTC)

@ruestique You're on Arch, and not Manjaro / others, right? Try downloading the package, and just run makepkg -sric.

When does the crash occur? Is it from opening unreal or opening a project?

ruestique commented on 2018-11-09 23:29 (UTC)

The paths are messed up again -_- but now it's causing crash at the start, any ideas?

VulkanRHI::vkEnumeratePhysicalDevices(Instance, &GpuCount, nullptr) failed, VkResult=-3 at /home/chibo/HGST/.cache/makepkg/unreal-engine/src/UnrealEngine/Engine/Source/Runtime/VulkanRHI/Private/VulkanRHI.cpp:453 with error VK_ERROR_INITIALIZATION_FAILED

where no any files in the cache folder obviously ~_~

4.20.3 works with clang 7. There seems to be an issue with opening projects. Looks like Unreal automatically skips recompiling project versions for the current engine. Not sure how to approach this.

Please more info about "Otherwise add -Wno-constant-logical-operand -Wno-return-std-move -Wno-self-assign-field -Wno-self-assign-overloaded". Where exactly that shall be added?

moadib commented on 2018-10-12 09:01 (UTC)

If PKGBUILD will use bundled toolchain (5.0 for 4.20, 6.0 for 4.21) then there is no need to race for clang updates.

Otherwise add -Wno-constant-logical-operand -Wno-return-std-move -Wno-self-assign-field -Wno-self-assign-overloaded and replace -nopie with --no-pie in LinuxToolchain.cs to support clang 7

However, there was another issue afterwards during the build() phase of the making of the 4.20.2 package: more specifically, with the build of the UE4Editor target which failed because of an error during the compiling of the Module.SensibleEditorSourceCodeAccess.cpp object:

The problem is that the ModuleManager.h header file is located in the Modules directory in the include path, and that's why it should be included as Modules/ModuleManager.h instead of ModuleManager.h.

I fixed the issue in this pull request to the upstream repo for the SensibleEditorSourceCodeAccess plugin. I hope that my fix will be merged soon into the master branch of that repo so that everyone would benefit from it.

Downgrading the clang, llvm-libs and lld packages to version 6.0.0 solved the Clang version issue for me (at least for the duration of the 4.20.2 build of UE).

To be more specific, I downgraded the packages as follows: clang to version 6.0.0-1, llvm-libs to version 6.0.0-4, lld to version 6.0.0-1.

I know that this is an ugly workaround but I couldn't think of a better solution.

I can not build because of clang version issue.
