Problem building UE4 on Linux

Development Programming & Scripting C++

Hi,

I’m trying to build UE4 on Linux (OpenSuse 13.1 64-bit), according to A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums.
I launched command:

$ make UE4Editor UE4Game UnrealPak CrashReportClient ShaderCompileWorker UnrealLightmass

During build process, an the following errors occurred:

Can someone help ?

Thanks in advance,

Which version of clang did you use? According to my experience, clang 3.6 is OK on Ubuntu and CentOS.

3

llvm-clang-3.3-6.4.1.x86_64, installed from repository.

4

I upgraded to clang 3.5, installed libicu53 and everything builds.

However, during build process, I got messages like this:

Nedless to say, directory /home//dev/Unreal/UnrealEngine/Engine/Binaries/Linux/ exists.

At the end, executables are produced. UE4Editor launches and looks OK, but when I try to create new project (C++ / Basic) the editor creates project directory with files and suddenly quits:

Do I miss something ?

More info:

When I start UE4Editor again after it quit previously, “Projects” section in Project Browser is empty, although it created project directory with files.
I guess it quits prematurely for some reason and new project setup is not finished.

Did anyone get similar problem, especially on OpenSUSE ? I’m trying to dig through forums, but without success.

Also, there are messages during editor startup, I’m not sure if it;s relevant here:
