Good evening, I’m sorry for stupid questions.

I asked a question [Linux] Opening project settings crashes editor - Platform & Builds - Epic Developer Community Forums

and checked the versions 14.3, 14.4, and when i opening the project`s settings the editor crash with the logs:

When i checked version 15, the editor did not start because he did not find the openGL 4.3 library on my PC.

I use Fedora 20, in my computer the video card is intel hd graphics 4000 it use openGL 3.1.

Maybe I’m doing something wrong and I do not know a lot of things, I will be glad if you tell and guide me in the right direction.

Сan it depend by the Linux kernel?

Did you try building from clean clone? I had similar issues when switching branches and rebuilding(or when I moved the source code to a different location). Also there was this PR that I am not sure is in 4.14 that also caused editor crash when opening the project settings https://github.com/EpicGames/UnrealEngine/pull/2976

Does /home//UnrealEngine/Engine/Binaries/Linux/ exist?

Yes, i cheked it

Yes, i had clean install master version, 15, 14.3 and 14,4. It is my first use the UE on linux.

I don’t know what this error means:

Fatal error: [File:/home//UnrealEngine/Engine/Source/Runtime/Core/Private/Linux/LinuxPlatformProcess.cpp] [Line: 857]

Hey Peterakk-

As you mentioned in the post you linked, this crash is related to how the DotNET folder is being . The pull request for this issue (https://github.com/EpicGames/UnrealEngine/pull/2945) has been checked and should resolve the crash in 4.15. Please let us know if you continue getting this crash after the 4.15 release and we will investigate further.


Thenks, but in 4.15 i have the next problem Editor crash with Could not create OpenGL 4.3 - Platform & Builds - Epic Developer Community Forums

I am going to arch and test on it. I think it problem on this distros.

I build 4.15 from a clean pull from the git… the crash persist
Couldn’t get a fresh pull from master to work yesterday; it launched as a blank square on my desktop
Today after fresh pull and build of promoted I get the same problem

I “https://github.com/EpicGames/UnrealEngine/pull/2945” and was under the impression that the fix would have been pushed into the 4.15 or the promoted branch by now…

Could someone point me to the exact code that needs to be patched so I can manually change it myself. I really do need project setting working


Hey -

This issue still occurring in 4.15.1 has been reported for further investigation here: Unreal Engine Issues and Bug Tracker (UE-43444)
