How to build CARLA on Linux
|
||
|
|
===========================
|
||
|
|
|
||
|
|
This guide has been tested only on Ubuntu 16.04.
|
||
|
|
|
||
|
|
Install the build tools
|
||
|
|
|
||
|
|
$ sudo apt-get install build-essential cmake ninja-build
|
||
|
|
|
||
|
|
To avoid compatibility issues between Unreal Engine and the CARLA dependencies,
|
||
|
|
the best configuration is to compile everything with the same compiler version
|
||
|
|
and C++ runtime library. We use clang 3.9 and LLVM's libc++.
|
||
|
|
|
||
|
|
Install clang 3.9
|
||
|
|
|
||
|
|
$ wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add -
|
||
|
|
$ sudo apt-get update
|
||
|
|
$ sudo apt-get install -y clang-3.9 clang++-3.9
|
||
|
|
|
||
|
|
You may need to change your default clang version to compile Unreal
|
||
|
|
|
||
|
|
$ sudo ln -s /usr/bin/clang-3.9 /usr/bin/clang
|
||
|
|
$ sudo ln -s /usr/bin/clang++-3.9 /usr/bin/clang++
|
||
|
|
|
||
|
|
Build Unreal Engine
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Download and compile Unreal Engine 4.17. Here we will assume you install it at
|
||
|
|
"~/UnrealEngine_4.17", but you can install it anywhere, just replace the path
|
||
|
|
where necessary.
|
||
|
|
|
||
|
|
Unreal Engine repositories are set to private. In order to gain access you need
|
||
|
|
to add your GitHub username when you sign up at https://unrealengine.com.
|
||
|
|
|
||
|
|
$ git clone --depth=1 -b 4.17 https://github.com/EpicGames/UnrealEngine.git ~/UnrealEngine_4.17
|
||
|
|
$ cd ~/UnrealEngine_4.17
|
||
|
|
$ ./Setup.sh && ./GenerateProjects.sh && make
|
||
|
|
|
||
|
|
Check Unreal's documentation
|
||
|
|
["Building On Linux"](https://wiki.unrealengine.com/Building_On_Linux) if any of
|
||
|
|
the steps above fail.
|
||
|
|
|
||
|
|
Setup CARLA plugin
|
||
|
|
------------------
|
||
|
|
|
||
|
|
Go to "CARLAUE4/Plugins/Carla" folder and run the setup script. This downloads
|
||
|
|
and compile all the dependencies, takes a while but you only need to do this
|
||
|
|
once
|
||
|
|
|
||
|
|
$ ./Setup.sh
|
||
|
|
|
||
|
|
Now you can use the Makefile to compile and test the code. However, the rebuild
|
||
|
|
script of the main project will do that already, see next section.
|
||
|
|
|
||
|
|
It is recommended to do a check to see if everything worked fine
|
||
|
|
|
||
|
|
$ make check
|
||
|
|
|
||
|
|
Build and launch CARLAUE4
|
||
|
|
-------------------------
|
||
|
|
|
||
|
|
Define the environment variable `UE4_ROOT` pointing to Unreal Engine's
|
||
|
|
installation folder.
|
||
|
|
|
||
|
|
In the root folder of CARLAUE4 you can find "Rebuild.sh" script. This deletes
|
||
|
|
all intermediate files, rebuilds whole CARLA, and launches the editor. Use it
|
||
|
|
every time you update CARLA.
|
||
|
|
|
||
|
|
$ UE4_ROOT=~/UnrealEngine_4.17 ./Rebuild.sh
|
||
|
|
|
||
|
|
It looks at the environment variable `UE4_ROOT` to find the right version of
|
||
|
|
Unreal Engine. You can also add this variable to your "~/.bashrc" or similar.
