@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 I'm not sure if this is what you are asking, but MAKEFLAGS can be specified in /etc/makepkg.conf.

zerophase commented on 2016-06-04 01:39 (UTC)

@acerix Yeah, I put -j24 in the first time, which makes sense it would fail. (works great for compiling kernels) The next time I built after deleting everything, and redownloading didn't put a -j argument in, and still it failed at the same point. Just had to try compiling again. Wonder if I have an excuse to go up to 64 gigs of ram. I'm saving to disk, and using makepkg directly to build. Do the MAKEFLAGS get dropped in, even if it isn't specified, in the build step?

acerix commented on 2016-06-03 22:58 (UTC)

@zerophase Unfortunately, makepkg does not support shallow clone, and Allan says "Won't implement": https://bugs.archlinux.org/task/34677 However, I think it's a good suggestion seeing how the saving would be about 7 GiB here, and git+ssh seems like the only way to download from a private github repo, so maybe this feature would be considered again for this use case. Another option is to modify makepkg: https://www.reddit.com/r/archlinux/comments/3nz1r4/question_for_arch_devs_makepkg_and_git_why_not/cvsu79m Regarding the build, it does support multicore building and I didn't have any issue doing a clean build using -j4. You might be running out of memory trying to build so many things as once; especially since it seems to spawn 4 clang processes for each make process, so that would mean 96 running at once. Let me know what errors you get in the output if it happens again.

zerophase commented on 2016-06-03 05:16 (UTC)

I don't know what the issue is exactly, but the first time I ran makepkg the build failed. The second time I ran the command make fixed whatever went wrong, and installed successfully. It might be that I have MAKEFLAGS set to -j24. I'm guessing the engine isn't configured for multicore compilation, so maybe try -j1 after the make command?

zerophase commented on 2016-06-03 03:03 (UTC)

is there anyway to get makepkg(without editing makepkg itself) to just use a shallow git clone, so we don't have to download the entire Unreal history?

acerix commented on 2016-05-16 15:28 (UTC)

No problem, glad you got it working. It doesn't really make sense for the GUI to disappear for that long, especially when they have loading screens for other stuff. I added a note on this to the Arch wiki.

Oh wow, it was user error. Clicking yes to recompile the project works, it just runs completely in the background showing no sign of actually doing anything. If you don't open it through a terminal the only way to notice it is to look at the processes with ksysguard/htop/etc. When I first clicked yes I probably rebooted before it could finish and didn't notice it was actually compiling it. Thanks so much for the help!

acerix commented on 2016-05-15 22:06 (UTC)

Ahh, I had only tried the blueprint mode so far, I didn't realize you meant the the c++ mode. I just tried that and got the same result; the create step seems to work, but it never opens. Instead the new .workshop file opened in my text editor, so presumable that's supposed to open in UE4Editor instead. When I opened the new project from the launch screen, I got the popup asking to compile the missing module, and after clicking Yes, it started compiling 789 modules which took a half-hour or so. After that, it opened properly though, so you might find something looking in the output of that compiling.

Here is the output from creating a new code project: http://pastebin.com/raw/79Vx5GJa From what I can tell the editor creates it OK but has trouble with it afterwards. It creates a process for the new project then that process closes/crashes and the editor exits.

I may well be doing something wrong so I'll read up on the manual a bit more then ask on the forum if there's nothing obvious.

Your specs sound fine, and I don't see any obvious errors in your output. Maybe the output from creating a project would show something.
