Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UE4 Editor doesn't open on Linux - OpenGL 3.2 Context SDL Error

The building of the source code occurs without any problem. But when I run the command for the Editor it just crashes without even opening it. The terminal shows this output:

I can advice you to install SDL library from sources https://www.libsdl.org/ or from third-party libraries that located in Unreal Engine repository. It may be helps you.

Hey GFerraz-

This crash is being investigated (UE-11671) to determine the exact cause. Please let us know if you are also having this error when using a another version of the engine?

Cheers

Doug Wilson

I was busy for a while. But I will have a try with other versions and see the results.

Cheers, GFerraz

I am getting this error on 4.7.4 off Ubuntu 14.04 64 Bit. Just ran it this morning and I am still getting it.

Hey qdelpeche-

What graphics card and drivers are you using? Did you try creating the 3.2 context with a standalone program as RCL suggested below?

My graphics card is a ATI Radeon HD6770 GDDR5 1GB. The driver it's the AMD proprietary version 14.12.

If your drivers cannot create 3.2 OpenGL context that is a showstopper for the editor. Try creating 3.2 context with a standalone program (like this one - https://www.opengl.org/wiki/Tutorial1:_Creating_a_Cross_Platform_OpenGL_3.2_Context_in_SDL_%28C_/_SDL%29) to double check that this is not Unreal Engine-related.
