# openpilot tools

## System Requirements

openpilot is developed and tested on **Ubuntu 20.04**, which is the primary development target aside from the [supported embedded hardware](https://github.com/commaai/openpilot#running-on-a-dedicated-device-in-a-car).

Running natively on any other system is not recommended and will require modifications. On Windows you can use WSL, and on macOS or incompatible Linux systems, it is recommended to use the dev containers.

## Native setup on Ubuntu 20.04

**1. Clone openpilot**

NOTE: This repository uses Git LFS for large files. Ensure you have [Git LFS](https://git-lfs.com/) installed and set up before cloning or working with it.

Either do a partial clone for faster download:
``` bash
git clone --filter=blob:none --recurse-submodules --also-filter-submodules https://github.com/commaai/openpilot.git
```

or do a full clone:
``` bash
git clone --recurse-submodules https://github.com/commaai/openpilot.git
```

**2. Run the setup script**

``` bash
cd openpilot
git lfs pull
tools/ubuntu_setup.sh
```

Activate a shell with the Python dependencies installed:
``` bash
poetry shell
```

**3. Build openpilot**

``` bash
scons -u -j$(nproc)
```

## Dev Container on any Linux or macOS

openpilot supports [Dev Containers](https://containers.dev/). Dev containers provide customizable and consistent development environment wrapped inside a container. This means you can develop in a designated environment matching our primary development target, regardless of your local setup.

Dev containers are supported in [multiple editors and IDEs](https://containers.dev/supporting), including Visual Studio Code. Use the following [guide](https://code.visualstudio.com/docs/devcontainers/containers) to start using them with VSCode.

#### X11 forwarding on macOS

GUI apps like `ui` or `cabana` can also run inside the container by leveraging X11 forwarding. To make use of it on macOS, additional configuration steps must be taken. Follow [these](https://gist.github.com/sorny/969fe55d85c9b0035b0109a31cbcb088) steps to setup X11 forwarding on macOS.

## WSL on Windows

[Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/about) should provide a similar experience to native Ubuntu. [WSL 2](https://docs.microsoft.com/en-us/windows/wsl/compare-versions) specifically has been reported by several users to be a seamless experience.

Follow [these instructions](https://docs.microsoft.com/en-us/windows/wsl/install) to setup the WSL and install the `Ubuntu-20.04` distribution. Once your Ubuntu WSL environment is setup, follow the Linux setup instructions to finish setting up your environment. See [these instructions](https://learn.microsoft.com/en-us/windows/wsl/tutorials/gui-apps) for running GUI apps.

**NOTE**: If you are running WSL and any GUIs are failing (segfaulting or other strange issues) even after following the steps above, you may need to enable software rendering with `LIBGL_ALWAYS_SOFTWARE=1`, e.g. `LIBGL_ALWAYS_SOFTWARE=1 selfdrive/ui/ui`.
