@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.

@acerix Hello, I have added two patches for it: please see https://github.com/walkthetalk/aurpackages/tree/master/unreal-engine

fix_dependency.patch: fix for UE4Editor link error - undefined reference FEditorStyle::Instance (libSourceControl.so need it)

remove_sysctl_include.patch: remove sysctl.h which is deprecated in glibc, I removed it simply, (it looks like is needed on other system, e.g. BSD)

I added a patch to allow Clang 9 because it specifically prevents compiling with Clang > 8. Compilation seemed to be going ok, but finally ended with this unhelpful error:

[2081/2083] Link (ld) libUE4Editor-Advertising.so
[2082/2083] Copy AgentInterface.dll
make: *** [Makefile:588: UE4Editor] Error 5
==> ERROR: A failure occurred in build().

Might be hard to get it to build with Clang 9 until Epic adds support.

@zerophase when will be Clang 9 fixed?

zerophase commented on 2019-10-15 20:26 (UTC)

@pr0me7heu2 you can undo the patches for using the system compiler, or fix the errors from clang 9. I'll be doing the latter over the next few days.

pr0me7heu2 commented on 2019-10-15 01:12 (UTC)

This looks to not be compatible with Clang 9 as I got this error today:

Building UnrealVersionSelector... ves_icall_TypeBuilder_create_runtime_class_raw USED 132 handles

Using 'git status' to determine working set for adaptive non-unity build (/home/$USER/.cache/yay/unreal-engine/src/UnrealEngine). Creating makefile for UnrealVersionSelector (no existing makefile) ERROR: This version of the Unreal Engine can only be compiled with clang 8.0, 7.0 and 6.0. clang 9.0.0 may not build it - please use a different version. make: *** [Makefile:5: UnrealVersionSelector-Linux-Shipping] Error 5 ==> ERROR: A failure occurred in prepare(). Aborting... Error making: unreal-engine

Is there a work around that I am missing in the comments?

@diogobaeder - Epics hates FLOSS community, they completely under Autodesk, Intel, nvidia, Microsoft patronize....

So you pay money - you get support, so on Linux you free ;-)

diogobaeder commented on 2019-10-02 21:23 (UTC)

Has anybody ever tried to ask Epic for storage somewhere for storing the compiled engine? I mean, of course it's our interest, but I think there might be a chance the company wants to help our community getting our hands on the engine easier. One of the users here even uses Unity instead of Unreal just because of that.

@wolfyrion that being said, I do have a patch I can put together for enabling ccache support that might offer compile length improvements for future compiles you're welcome to try out. For me it speeds up recompiling the various libraries, while not improving the actual engine compile. You might notice greater speed ups than me with how long you take to compile. How's your system setup, in terms of compiling Unreal? Do you have enough ram to compile in memory?
