CARLA is an open-source simulator for autonomous driving research. CARLA has been developed from the ground up to support development, training, and
validation of autonomous driving systems. In addition to open-source code and protocols, CARLA provides open digital assets (urban layouts, buildings,
vehicles) that were created for this purpose and can be used freely. The simulation platform supports flexible specification of sensor suites and
environmental conditions.

Building CARLA
--------------

Use `git clone` or download the project from this page. Note that the master branch contains the most recent release of CARLA with the latest fixes and features.

Then follow the instruction at [How to build on Linux][buildlinuxlink] or [How to build on Windows][buildwindowslink].  
The Linux build needs for an UE patch to solve some visualization issues regarding Vulkan. Those already working with a Linux build should install the patch and make the UE build again using the following commands.  
```sh
# Download and install the UE patch  
cd ~/UnrealEngine_4.24
wget https://carla-releases.s3.eu-west-3.amazonaws.com/Linux/UE_Patch/430667-13636743-patch.txt ~/430667-13636743-patch.txt
patch --strip=4 < ~/430667-13636743-patch.txt
# Build UE
./Setup.sh && ./GenerateProjectFiles.sh && make
```

Unfortunately we don't have official instructions to build on Mac yet, please check the progress at [issue #150][issue150].
