MacOS 개발 환경

아래에서 macOS용 PX4 개발 환경 설정 방법을 설명합니다. PX4 빌드에 사용되어 집니다.

TIP

This setup is supported by the PX4 dev team. To build other targets you will need to use a different OS (or an unsupported development environment).

영상 가이드

Base Setup

The "base" macOS setup installs the tools needed for building firmware, and includes the common tools that will be needed for installing/using the simulators.

Environment Setup

Details

Apple Silicon Macbook users! If you have an Apple M1, M2 etc. Macbook, make sure to run the terminal as x86 by setting up an x86 terminal:

  1. Locate the Terminal application within the Utilities folder (Finder > Go menu > Utilities)
  2. Select Terminal.app and right-click on it, then choose Duplicate.
  3. Rename the duplicated Terminal app, e.g. to x86 Terminal
  4. Now select the renamed x86 Terminal app and right-click and choose *Get Info
  5. Check the box for Open using Rosetta, then close the window
  6. Run the x86 Terminal as usual, which will fully support the current PX4 toolchain

First set up the environment

  1. Enable more open files by appending the following line to the ~/.zshenv file (creating it if necessary):

    sh
    echo ulimit -S -n 2048 >> ~/.zshenv

    INFO

    If you don't do this, the build toolchain may report the error: "LD: too many open files"

:::

  1. Enforce Python 3 by appending the following lines to ~/.zshenv

    sh
    # Point pip3 to MacOS system python 3 pip
    alias pip3=/usr/bin/pip3

공통 도구

To setup the environment to be able to build for Pixhawk/NuttX hardware (and install the common tools for using simulators):

  1. Install Homebrew by following these installation instructions.

  2. Run these commands in your shell to install the common tools:

    sh
    brew tap PX4/px4
    brew install px4-dev
  3. Install the required Python packages:

    sh
    # install required packages using pip3
    python3 -m pip install --user pyserial empty toml numpy pandas jinja2 pyyaml pyros-genmsg packaging kconfiglib future jsonschema
    # if this fails with a permissions error, your Python install is in a system path - use this command instead:
    sudo -H python3 -m pip install --user pyserial empty toml numpy pandas jinja2 pyyaml pyros-genmsg packaging kconfiglib future jsonschema

Gazebo Classic Simulation

To setup the environment for Gazebo Classic simulation:

  1. Run the following commands in your shell:

    sh
    brew unlink tbb
    sed -i.bak '/disable! date:/s/^/  /; /disable! date:/s/./#/3' $(brew --prefix)/Library/Taps/homebrew/homebrew-core/Formula/tbb@2020.rb
    brew install tbb@2020
    brew link tbb@2020

    INFO

    September 2021: The commands above are a workaround to this bug: PX4-Autopilot#17644. They can be removed once it is fixed (along with this note).

:::

  1. To install SITL simulation with Gazebo Classic:

    sh
    brew install --cask temurin
    brew install --cask xquartz
    brew install px4-sim-gazebo
  2. Run the macOS setup script: PX4-Autopilot/Tools/setup/macos.sh The easiest way to do this is to clone the PX4 source, and then run the script from the directory, as shown:

    sh
    git clone https://github.com/PX4/PX4-Autopilot.git --recursive
    cd PX4-Autopilot/Tools/setup
    sh macos.sh

다음 단계

명령줄 도구 모음 설정후, 다음을 수행합니다.

  • Install VSCode (if you prefer using an IDE to the command line).

  • Install the QGroundControl Daily Build

    TIP

    The daily build includes development tools that are hidden in release builds. 또한, 릴리스 빌드에서 아직 지원되지 않는 새로운 PX4 기능에 대한 액세스를 제공할 수도 있습니다.
