@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.

For me, the Engine fails to compile pre-existing projects (from Windows) with and error about what was compiled would affect installed engine files (somehow)

It also refuses to open the project if the Makefile was run with in the terminal as well

------- Build details --------
Using toolchain located at '/opt/unreal-engine/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/x86_64-unknown-linux-gnu'.
Using clang (/opt/unreal-engine/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/x86_64-unknown-linux-gnu/bin/clang++) version '10.0.1' (string), 10 (major), 0 (minor), 1 (patch)
Using bundled libc++ standard C++ library.
Using lld linker
Using llvm-ar : /opt/unreal-engine/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/x86_64-unknown-linux-gnu/bin/llvm-ar
Using fast way to relink  circularly dependent libraries (no FixDeps).
------------------------------
ERROR: Building would modify the following engine files:

       /opt/unreal-engine/Engine/Binaries/Linux/AgentInterface.dll
       /opt/unreal-engine/Engine/Binaries/Linux/Android/libUE4Editor-AndroidDeviceDetection.so
       /opt/unreal-engine/Engine/Binaries/Linux/Android/libUE4Editor-AndroidPlatformEditor.so

(and many more; too many to fit here)

and doing it in the terminal seems to work but doing so compiles what's needed on my OS drive which is low on space from the engine enough as it is x_x

Would be great if it did that in the project folder so it doesn't eat my SSD alive)

I read in a compilation guide from Epic to use chmod -R a+rwX on UnrealEngine/Engine after everything is "said and done installed". I've never had permissions issues or crashes (relating to permissions, hah...).

Tabulate commented on 2021-03-25 14:06 (UTC)

On line 125, you're trying to change the permissions to a777 which doesn't exist. You probably want to change this to 777 which is what I'm assuming is what you meant to put. https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=unreal-engine#n125

zerophase commented on 2021-03-25 02:17 (UTC)

Fixed the permission issue when running the engine. Just made the whole unreal folder have full permissions. If you want to dig through, and figure out which files need the ability to execute feel free to do that. I'm having issues with mono not having the permissions needed to execute.

zerophase commented on 2021-03-23 22:36 (UTC)

Added support for packaging with system compiler. Will bump release number when compiling in engine works.

@pgaleone You need to pass -ForceUseSystemCompiler when compiling. I think you can set compile arguments through the engine. Personally, I use make.

make ARGS=-ForceUseSystemCompiler in your project directory will compile it. I can tell you how to do it through engine in a bit.

There's also a toggle in the PKGBUILD for turning the system compiler on or off. It was supposed to be checked off. when committed.

broken the unreal project's generation and building.

Now every time I try to compile a project, the build tool fails with

I guess the following line, added in the lastest commit (https://aur.archlinux.org/cgit/aur.git/commit/PKGBUILD?h=unreal-engine&id=72c2a8f44f52564416410721fa587213a84755e3) should be uncommented

# mv Engine/Build "$pkgdir/$dir/Engine/Build"

otherwise any project we try to build using this engine fails with Engine/Build/BatchFiles/Linux/Build.sh: No such file or directory

@zerophase, I hope it goes well then. :)
