@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).

@shatur

It needed only if you generate CMake project. What if I add it as optional dependencies with qmake that used in the same way?

Yeah, just drop cmake in optdepends with qmake.

I'll be able to look into the system clang after the holidays.

Cmake should probably be in optdepends, as it is needed for different ides.

There should be a patch applied that uses the system clang, and stops downloading of the toolchain.

After 4.24 Unreal Engine do not allow to use system Clang :( If I apply a patch that disables downloading Clang toolchain, Unreal Engine will not use the system Clang and fail to build. Maybe there is the way how to path it, but for now I do not know how to fix it.

Most of those patches probably need to be updated for changes in the engine so they still apply successfully. They're mostly for supporting the system clang, and recompiling the Unreal Version selector so you don't have to manually intervene during install time.

I checked all the old patches, they are applied successfully, but they are no longer needed. Except the patch to use the system Clang, which also patches successfully, but then the builder does not see the system Clang. I don’t know how to fix it yet.

Have you run the engine through various paths to check for any crashes from removing Windows specific files? There are a few checks built into the engine.

Of course! At the moment, I managed to reduce the size of the downloaded files from 11 to 5.5 GiB (via .gitdepsignore, excluding from the download files Windows, Mac, IOS and other OSs, the compilation of which is not supported under Linux.

@niqingliang2003, I'm working on it now. I decided to rewrite PKGBUILD from scratch, here is my changes:

  • I moved downloading of Unreal Engine to prepare section. This allows me to explicitly check access to the repository (and notify user about it!) and specify --depth=1 to reduce the amount of downloaded data from repo to 200 MiB.
  • I removed cmake from makedepends because it is not used.
  • After 4.24 Unreal Engine disallow to use system clang. Even if setup script do not download the toolchain, the builder will not see the system clang. Perhaps this can also be fixed, but so far there is no solution, so I suggest using the proposed clang for now.
  • I removed all obsolete patches and updated all information, now PKGBUILD looks clean.
  • PKGBUILD now works with the latest (4.24.1) version.
  • I renamed .desktop file to com.unrealengine.UE4Editor to follow desktop entry specifications and renamed icon to lower case for desktop icon themes compatibility.

You can get it here if you want it now (you will need to rename UE4Editor.desktop to com.unrealengine.UE4Editor.desktop). I am currently working on cleaning garbage (.lib, .a and other). As soon as I finish, I will push these changes, let me a few days.

how about new 4.24 release?

eyupgurel commented on 2019-12-15 12:49 (UTC)

Never mind any release above 4.22-3. First and foremost this freezing issue must be sorted out. Freezing will annihilate any promised advantages offered by newer versions.

i also have the 3 second freeze (its not random!!!). Last working version is 4.22-3-release! Also master has the freezing. I tryed every tip i could find but no luck. gfx is a 1070ti nvdriver is 440-36.

@galaxy0419 thanks! I disabled it already, and enabled/disabled compositor, still same result.

on my pc, freeze every 3 seconds, but not random freeze.

and on another pc with amd old video card, work as expected.
