Do not install 4.23.1 UE4Editor freezes intermittently. Impossible to use in production.

@niqingliang2003 Thanks and nice work, I was able to compile and added your patches.

I don't know of a way to skip stripping on some files. I think those binaries are used in cross-compilation, when I tried to delete them before it made the editor crash.

@tomsk I also get that error, but I'm not sure if they dropped support for cards without Vulkan or if we could add a patch for opengl support.

can we skip to strip the mac/windows binaries? or even don't install mac/windows binaries?

Does anybody have this problem?

  1. the ue4editor will freeze every 3 seconds.

  2. the project packaged can't start for vulkan initialize failed.

@acerix Hello, I have added two patches for it: please see

fix_dependency.patch: fix for UE4Editor link error - undefined reference FEditorStyle::Instance ( need it)

remove_sysctl_include.patch: remove sysctl.h which is deprecated in glibc, I removed it simply, (it looks like is needed on other system, e.g. BSD)

I added a patch to allow Clang 9 because it specifically prevents compiling with Clang > 8. Compilation seemed to be going ok, but finally ended with this unhelpful error:

[2081/2083] Link (ld)
[2082/2083] Copy AgentInterface.dll
make: *** [Makefile:588: UE4Editor] Error 5
==> ERROR: A failure occurred in build().

Might be hard to get it to build with Clang 9 until Epic adds support.

@zerophase when will be Clang 9 fixed?

zerophase commented on 2019-10-15 20:26

@pr0me7heu2 you can undo the patches for using the system compiler, or fix the errors from clang 9. I'll be doing the latter over the next few days.

This looks to not be compatible with Clang 9 as I got this error today:

Building UnrealVersionSelector... ves_icall_TypeBuilder_create_runtime_class_raw USED 132 handles

Aborting... Error making: unreal-engine

Is there a work around that I am missing in the comments?
