Many different issues can be dragged during the build installation, and show like this. Here is a list of the most likely reasons why.
|
||||
|
||||
* __Run Unreal Engine 4.22:__ Something may have failed when building Unreal Engine. Try running UE editor on its own and check out that it is the 4.22 release.
|
||||
* __Download the assets:__ The server will not be able to run without the visual content, so this step is mandatory even when building CARLA for the first time. Go to the root CARLA folder and run the script to get the assets: `./Update.sh`
|
||||
* __UE4_ROOT is not defined:__ The environment variable is not set. Remember to make it persistent session-wide by adding it to your `~/.bashrc` or `~/.profile`, otherwise it will need to be set for every new shell. Run `export UE4_ROOT=~/UnrealEngine_4.22` to set the variable this time. Make sure that the path leads to the UE 4.22 main folder.
|
||||
* __Check dependencies:__ Confirm that everything was installed properly during the first steps of the process. Maybe one of the commands was skipped, unsuccessful or the dependencies were not suitable for the system.
|
||||
* __Delete CARLA and clone it again:__ Just in case something went wrong. Delete your version of CARLA and try cloning or downloading and extracting it again. Then follow the steps from there.
|
||||
* __Meet system requirements:__ Ubuntu version should be 16.04 or later. CARLA needs around 15GB of disk space and a dedicated GPU (or at least one with 4GB) to run.

## Requirements
|
||||
<h4>System specifics</h4>
|
||||
|
||||
* __Ubuntu 16.04 or later:__ Currently migrating to Ubuntu 18, but there is support up to Ubuntu 16.04.
|
||||
* __30GB disk space:__ Installing all the software needed and CARLA itself will require quite a lot of space, especially Unreal Engine. Make sure to have around 30/50GB of free disk space.
|
||||
* __An adequate GPU:__ CARLA aims for realistic simulations, so the server needs at least a 4GB GPU. A dedicated GPU is highly recommended for machine learning.
|
||||
* __Two TCP ports and good internet connection:__ 2000 and 2001 by default. Be sure neither firewall nor any other application are blocking these.

#### Dependencies

### Dependencies
|
||||
|
||||
CARLA needs many dependencies to run. Some of them are built automatically during this process, such as *Boost.Python*. Others are binaries that should be installed before starting the build (*cmake*, *clang*, different versions of *Python* and much more). In order to do so, run the commands below in a terminal window.

|

First of all, a [GitHub](https://github.com/) account will be needed, as CARLA content is organized in different repositories in there. Also, [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) will be used in this build guide when facilitating commands to be run in terminal.

|
||||
|
||||
In order to access the Unreal Engine repositories, which are set to private, create an [Unreal Engine](https://www.unrealengine.com/en-US/feed) account and connect it to a GitHub account. To do so, there is a section in Unreal Engine's profile settings under the name of __Connected accounts__. [Here](https://www.unrealengine.com/en-US/blog/updated-authentication-process-for-connecting-epic-github-accounts) is a brief explanation just in case.

## Unreal Engine
|
||||
|
||||
The current version of CARLA runs on __Unreal Engine 4.22__ only, so the following steps will be downloading this version and building it. The path is irrelevant, but for the sake of this tutorial, installation will be done under `~/UnrealEngine_4.22`. If the path chosen differs, remember to change it accordingly when running the commands on terminal.
|
||||
The process described below can be found in this [complete guide](https://docs.unrealengine.com/en-US/Platforms/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow/index.html) on how to build Unreal Engine on Linux. It can be consulted if preferred, but remember though that CARLA will need the __4.22 release__, not the latest.

|
||||
* __An adequate GPU:__ CARLA aims for realistic simulations, so the server needs at least a 4GB GPU. A dedicated GPU is highly recommended for machine learning.

### Minor installations
|
||||
|
||||
Some software is needed for the build process the installation of which is quite straightforward.
|
||||
|
||||
* [CMake](https://cmake.org/download/): Generates standard build files from simple configuration files.
|
||||
* [Git](https://git-scm.com/downloads): Version control system to manage CARLA repositories.
|
||||
* [Make](http://gnuwin32.sourceforge.net/packages/make.htm): Executable generator.
|
||||
* [Python3 x64](https://www.python.org/downloads/): Main script language that CARLA provides support to. Having a x32 version installed may cause conflict even if the x64 is also there, so it is highly advisable to uninstall these.
|
||||
* [__CMake__](https://cmake.org/download/) generates standard build files from simple configuration files.
|
||||
* [__Git__](https://git-scm.com/downloads) is a version control system to manage CARLA repositories.
|
||||
* [__Make__](http://gnuwin32.sourceforge.net/packages/make.htm) generates the executables.
|
||||
* [__Python3 x64__](https://www.python.org/downloads/) is the main script language in CARLA. Having a x32 version installed may cause conflict, so it is highly advisable to have it uninstalled.
|
||||
|
||||
!!! Important
|
||||
Be sure that these programs are added to your [environment path](https://www.java.com/en/download/help/path.xml), so you can use them from your command prompt. The path values to add lead to the _bin_ directories for each software.

|
||||
|
||||
Get the 2017 version from [here](https://developerinsider.co/download-visual-studio-2017-web-installer-iso-community-professional-enterprise/). **Community** is the free version. Two elements will be needed to set up the environment for the build process. These must be added when using the Visual Studio Installer:

Get the 2017 version from [here](https://developerinsider.co/download-visual-studio-2017-web-installer-iso-community-professional-enterprise/). __Community__ is the free version. Use the _Visual Studio Installer_ to install two additional elements.
|
||||
|
||||
* **Windows 8.1 SDK**: On the right there is an _Installation details_ section. Find this SDK and select it.
|
||||
* **x64 Visual C++ Toolset**: In the main _Workloads_ section, choose **Desktop development with C++**. Thus will enable a x64 command prompt that will be used for the build. After installing, check this up by pressing the `Win` button and search for `x64` (be careful to **not open a `x86_x64` prompt**). The name of this command prompt can change a bit depending on the Visual Studio installed.
|
||||
* __Windows 8.1 SDK.__ Select it in the _Installation details_ section on the right.
|
||||
* __x64 Visual C++ Toolset.__ In the _Workloads_ section, choose __Desktop development with C++__. This will enable a x64 command prompt that will be used for the build. Check it up by pressing the `Win` button and searching for `x64`. Be careful to __not open a `x86_x64` prompt__.
|
||||
|
||||
!!! Important
|
||||
Having other Visual Studio versions may cause conflict during the build process, even if these have been uninstalled (Visual Studio is not that good at getting rid of itself and erasing registers). To completely clean Visual Studio from the computer run `.\InstallCleanup.exe -full` found in `Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout`. This may need admin permissions.

|
||||
|
||||
!!! Note
|
||||
This note will only be relevant if issues arise during the build process and manual build is required. Having VS2017 and UE4.22 installed, a **Generate Visual Studio project files** option should appear when doing right-click on **.uproject** files. If this option is not available, something went wrong while installing Unreal Engine and it may need to be reinstalled. Create a simple Unreal Engine project to check up.

Now the latest content for the project, known as `master` branch in the repository, has been copied in local.
|
||||
|
||||
!!! Note
|
||||
The `master` branch contains the latest fixes and features. Stable code is inside the `stable` branch, and it can be built by changing the branch. The same goes for previous CARLA releases. Always remember to check the current branch in git with `git branch`.

### Get assets
|

|
||||
Only the assets package, the visual content, is yet to be downloaded. `\Util\ContentVersions.txt` contains the links to the assets for every CARLA version. These must be extracted in `Unreal\CarlaUE4\Content\Carla`. If the path doesn't exist, create it.
|
||||
Download the **latest** assets to work with the current version of CARLA. When working with branches containing previous releases of CARLA, make sure to download the proper assets.

#### make CARLA
|
||||
Download the __latest__ assets to work with the current version of CARLA.
|
||||
|
||||
Go to the root CARLA folder, the one cloned from the repository. It is time to do the automatic build. The process may take a while, it will download and install the necessary libraries. It might take 20-40 minutes, depending on hardware and internet connection. There are different make commands to build the different modules:
|
||||
### make CARLA
|
||||
|
||||
Go to the root CARLA folder to make the build. The process may take a while, around 20-40 minutes, it will download and install the necessary libraries. There are different commands to build the different modules.
|
||||
|
||||
!!! Warning
|
||||
Make sure to run __make launch__ to prepare the server and __make PythonAPI__ for the client.
|
||||
Alternativelly __make libcarla__ will prepare the CARLA library to be imported anywhere.
|
||||
Alternatively __make libcarla__ will prepare the CARLA library to be imported anywhere.
|
||||
|
||||
* **launch** will compile the server simulator and launch it in Unreal Engine. Press Play to start the spectator view and close the editor window to exit. Camera can be moved with WASD keys and rotated by clicking the scene while moving the mouse around:
|
||||
```cmd
|
||||
|
||||
### make CARLA
|
||||
|
||||
The last step is to finally build CARLA. There are different `make` commands to build the different modules. All of them run in the root CARLA folder.
|
||||
|
||||
!!! Warning
|
||||
Make sure to run __make launch__ to prepare the server and __make PythonAPI__ for the client.
|
||||
Alternatively __make libcarla__ will prepare the CARLA library to be imported anywhere.

|
||||
```
|
||||
The project may ask to build other instances such as `UE4Editor-Carla.dll` the first time. Agree in order to open the project. Also, during the first launch Unreal Editor may show warnings regarding shaders and mesh distance fields. These take some time to be loaded and the city will not show properly until then.

|
||||
|
||||
* **PythonAPI** will compile the API client, necessary to grant control over the simulation. It is only needed the first time (remember to run it again when the CARLA code is updated). After building it, scripts can run. The following example will spawn some life into the city:
|
||||
```cmd
|
||||
make PythonAPI && cd PythonAPI/Examples && python3 spawn_npc.py
|
||||
* __make PythonAPI__ compiles the API client, necessary to grant control over the simulation. It is only needed the first time. Remember to run it again when updating CARLA. Scripts will be able to run after this command is executed. The following example will spawn some life into the town.
|
||||
|
||||
```sh
|
||||
make PythonAPI && cd PythonAPI/examples && python3 spawn_npc.py
|
||||
```
|
||||
!!! Important
|
||||
If the simulation is running at very low FPS rates, go to `Edit/Editor preferences/Performance` in the UE editor and disable __Use less CPU when in background__.
|
||||
|
||||
!!! Note
|
||||
If the simulation is running at very low FPS rates, open the UE4.22 editor and go to "Edit>Editor preferences>Performance" and disable: **Use less CPU when in background**.
