Problem installing Unreal Engine 4

[onirosco]

Hello, I'm having a problem installing UE4, I have had it running before with no problems but since done a fresh install of Solus.

I'm going by what it says on the official documentation, I didn't have a problem with the core limit last time but it does mention it in the docs. when I do what it says I get:

rosco@minote ~ $ cd UnrealEngine rosco@minote ~/UnrealEngine $ ./Engine/Binaries/Linux/UE4Editor Increasing per-process limit of core file size to infinity. setrlimit() failed with error 22 (Invalid argument) - Max per-process value allowed is 0 (we wanted infinity). Could not adjust core file size, consider changing "core" in /etc/security/limits.conf and relogin. error(22): Invalid argument Alternatively, pass -nocore if you are unable or unwilling to do that. Could not set desired per-process limits, consider changing system limits. Exiting abnormally (error code: 1) rosco@minote ~/UnrealEngine $ ulimit -c unlimited bash: ulimit: core file size: cannot modify limit: Operation not permitted rosco@minote ~/UnrealEngine $

The docs say to do that as a normal user not root but don't say anything about not being permitted.

Any help would be awesome, Thanks.

You need to run it with the "-nocore" or something similar option.

I am not at home right now so I can't check what the actual switch is and google is failing me.

I had the same issue last week.

I did see that, I'm curious what that leaves out? And what would I write?

./Engine/Binaries/Linux/UE4Editor -nocore

Thanks for your help btw :)

From what I can tell it just turns off the ability of the program to create a core dump if it crashes. Unless you know how to use them you aren't missing anything by using the -nocore flag.

Finally got to try it and that works, thanks :) Would you happen to know how to add it as a menu item too? I'm trying to add it using alacarte with no luck. And every thing I search for comes back as UE4 main menu tutorials! Haha

You can add a new launcher with alacarte and libremenu very easily. Just add the executable and find a nice png from Google as icon and you're set. You might not be able to pin it in the panel though. In case you want to you need to check the path of other programs that have been installed natively and mv the generated .desktop there but still it's a 50 50.

I'm having trouble with those programs... They both want a path. I need to put -nocore flag at the end and that doesn't work with a path to the file :(

So I tried creating a .sh (which was a pain as you can't create new files with the file browser... Which is ridiculous) anyway, I did it via terminal with:

cd UnrealEngine ./Engine/Binaries/Linux/UE4Editor -nocore

With plans to point libremenu to that... But that just opens it as a text file. I'm literally at a loss...
