@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).

@Majora320 try clearing the pacaur cache.

Now I'm getting: ``` patching file /home/moses/.cache/pacaur/unreal-engine/src/UnrealEngine/Engine/Source/ThirdParty/Linux/LibCxx/include/c++/v1/__locale Hunk #1 FAILED at 39 (different line endings). 1 out of 1 hunk FAILED -- saving rejects to file /home/moses/.cache/pacaur/unreal-engine/src/UnrealEngine/Engine/Source/ThirdParty/Linux/LibCxx/include/c++/v1/__locale.rej ``` I *think* the hash was wrong because the line endings were "\r\n" on the maintainer's machine, but git changed them to "\n".

I can't build the package. Things that I've done: 1. Update the checksum of xlocale-crash.patch in PKGBUILD 2. The xlocale-crash.patch patch was failing. In the function prepare(), the following line fails because the target file seems to be already patched: patch "$ue4src/ThirdParty/Linux/LibCxx/include/c++/v1/__locale" "$pkgbuild_dir/xlocale-crash.patch" I don't know if it's because I updating it and it's not a fresh install. But this file seems to be created every time I run `makepkg -so`. Maybe they fixed it in the upstream and the patch isn't needed anymore? I commented this line on PKGBUILD and the command `makepkg -so` finish successfully. 3. Building the code (`makepkg -se`) fails when linking CrashReportClient. A full log after I compiled everything and trying to run make again is here: https://pastebin.com/THseXvfj But the most important parts are this: ``` $ makepkg -se ==> Making package: unreal-engine 4.18.0-1 (Thu 26 Oct 00:07:21 -02 2017) ==> Checking runtime dependencies... ==> Checking buildtime dependencies... ==> WARNING: Using existing $srcdir/ tree ==> Removing existing $pkgdir/ directory... ==> Starting build()... bash "/home/user/build/unreal-engine/src/UnrealEngine/Engine/Build/BatchFiles/Linux/Build.sh" CrashReportClient Linux Shipping Building CrashReportClient...

@AllanDaemon @zerophase I'm getting 6495cfd1b03aef86d0aca15d5389b4d8ee2d745e900a1956391afcbb4a14dafe (same as AllanDaemon)

@majora420 @zerophase xlocale-crash.patch doesn't pass verification for me too. SHA256 of its with the file from the latest commit: 6495cfd1b03aef86d0aca15d5389b4d8ee2d745e900a1956391afcbb4a14dafe Changing the hash on PKGBUILD fixes and PS: I tried this and the hash stills the one I wrote. $ rm xlocale-crash.patch $ git checkout -- xlocale-crash.patch

Hey all, whats the best drivers to use with a AMD GPU (RX480) for UE4?, everytime I try to compile it and load it, it freezes the desktop and need to restart the whole PC, last time I used a Nvidia GPU and it just worked etc. Thanks.

@majora420 I'm getting for xlocale-crash.patch: d0fa5f1dd53846e84ce4a698cbdbedf647137c230b20fe1cabe3a3ffe0cf85c4 What do you have?

I patched the clang library (included with Unreal) so locale is used instead of xlocale in __locale. It fixes the whole xlocale compile errors. But, I don't know if it's going to cause weird crashes. If anyone experiences odd crashes that don't trace back to Unreal let me know.
