MacOS 是受支持的 PX4 开发平台。 根据本文的指示构建的开发环境可以用编译：
- 基于 NuttX 的硬件 (Pixhawk等)
- jMAVSim 仿真模拟
- Gazebo Simulation
若需要为其他平台进行编译请参考： Toolchain Installation > Supported Targets。
Increase the maximum allowed number of open files on macOS using the Terminal command:
ulimit -S -n 2048
At time of writing (December 2018) the master branch uses more than the default maximum allowed open files on macOS (256 in all running processes). As a short term solution, increasing the number of allowed open files to 300 should fix most problems.
The installation of Homebrew is quick and easy: installation instructions.
After installing Homebrew, run these commands in your shell to install the common tools:
brew tap PX4/px4 brew install px4-dev
Make sure you have Python 3 installed.
brew install python3 # install required packages using pip3 pip3 install --user pyserial empy toml numpy pandas jinja2 pyyaml pyros-genmsg packaging
To install SITL simulation with Gazebo:
brew cask install xquartz brew install px4-sim-gazebo
To install SITL simulation with jMAVSim:
brew tap AdoptOpenJDK/openjdk brew cask install adoptopenjdk8
brew install px4-sim-jmavsim
See Additional Tools for information about other useful development tools that are not part of the build toolchain (for example IDEs and GCSs).
Once you have finished setting up the environment, continue to the build instructions.
