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 latest fixes and features, for the latest stable code may be
best to switch to the `stable` branch.

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 url://... ~Download//430667-13636743-patch.txt
patch --strip=4 < ~/Downloads/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].
