Ok, the ispc issue does not impact us yet. It only seems to matter for 4.25.
UPDATE: Going to be a little git longer. Getting compile errors that do not occur with the latest dev build.

@zerophase, good news, I can test it.
seems to work with the version of ispc in community. I can have a patch up tomorrow if anyone wants to test if everything still works with our version of the engine.

@zerophase I can't open your link, can you paste here or give another link?
This is enough to recreate the Unreal startup issue if you want to track down where in their version of SDL2 everything breaks.
https://gist.github.com/Zerophase/81d6ac5d3801e5ec7820e27c8b32c390
The SDL2 being used by Unreal has issues with being initialized properly. I tried getting their step into third party code working on Linux to no Avail. It has something to do with SDL2 not being able to detect the proper video settings.
I tried filling a bug report with Epic, and got an email response saying, "works as intended."
Found a working workaround for the freezing issue!
thx to thejustinwalsh in Unrealforum.
Works in 4.24.1-release

done.
@Shatur So its seams limited to the 1070. Good to know. :-|

@juancarlospaco this is easily done on your own system, not in a PKGBUILD, given that building packages runs as root:
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).zerophase commented on 2021-05-27 08:15 (UTC) (edited on 2021-05-30 08:41 (UTC) by zerophase)
Will update to 5.0 when it is released.
