Building from scratch on Ubuntu Linux 16.04 LTS.

Getting the following output while trying to compile the up to date release branch:

bash "/home/vladius/UnrealEngine"/Engine/Build/BatchFiles/Linux/Build.sh CrashReportClient Linux Shipping

The issue can be fixed by manually compiling the hlslcc library:

cd Engine/Source/ThirdParty/hlslcc/hlslcc/projects/Linux
make
mv ../../lib/libhlslcc.a ../../lib/x86_64-unknown-linux-gnu

You need to run Setup.sh before attempting to build, this should recompiled libhlslcc.a for you.

Hi,
I had the same issue yesterday…
Visit also this page, Can't install UE4 on linux - Platform & Builds - Epic Developer Community Forums
I updated current path with the 4.13 I got from git.

  1. be sure to have clang, installed ( sudo apt-get install clang) to compile libhlslcc.a
  2. cd Engine/Source/ThirdParty/hlslcc/hlslcc/projects/Linux
  3. make
  4. mv …/…/lib/Linux/libhlslcc.a …/…/lib/Linux/x86_64-unknown-linux-gnu
