@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).

I have the same problem. Mesa AMDGPU Kernel driver here

Hi, @acerix Thanks, successfully build. Unfortunately, it's doesn't run... i get an error *** Error in `./UE4Editor': free(): invalid pointer: 0x00007f8b456ea560 *** Looks like it doesn't run on AMDGPU driver.

It turns out hardening-wrapper is now deprecated because the clang package in Arch has been modified to use SSP and PIE by default. https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/llvm&id=1d5568f96e56efb2186b3ae081488e1e5a509397 https://www.reddit.com/r/archlinux/comments/6n5tkp/arch_now_enables_pie_and_ssp_by_default_in_gcc/ I don't know what changes the engine needs for it to compile with PIE, so I added "no-pie" flags to the compile/linker which got it building.

kro007 commented on 2017-07-17 07:23 (UTC)

@zerophase hardening-wrapper is not installed on my computer. " Have any more information on your system ? " Arch x64 fully update ... many 32bits lib from multilib repo installed (for steam) what info do you need ?

Kerrex commented on 2017-07-17 07:08 (UTC)

I confirm that hardening-wrapper is uninstalled here

zerophase commented on 2017-07-16 21:56 (UTC)

@acerix I'm getting the issue too, and don't have hardening-wrapper installed.
