Linux - Compilation failed

I tried to compile the engine using Kubuntu 14.04. I followed the steps at the wiki. But I got an error while running the

This is what I get:

*** This version of the engine can only be compiled by clang - refusing to register the Linux toolchain.

Seems like your default “cc” and “c++” point at GCC, not CLang. Use update-alternatives or whatever your distro uses to switch (and if you haven’t installed clang/clang++, you need to do that, too!)

Thanks, I got it compiling.

But now I have a new issue. After starting the Editor I’m not able to read anything. Does someone know how to solve this?

I checked the console output during starting the UE4Editor. I think the problem is caused by the following lines:

[2015.04.30-19.52.51:200]  0]LogSlate:Warning: Failed to load font data from '../../../Engine/Content/Editor/Slate/Fonts/Roboto-Regular.ttf'

The files exist. Does someone know how to solve the problem?

Hi MyFreshP

If you read this A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums carefully you will find your answer.

I had that Font problem too. That fix Yaakuro linked is the one that works, :slight_smile:
