Building ArduPilot for Pixhawk/PX4 on Mac with MakeΒΆ

This article shows how to build ArduPilot for Pixhawk 2, Pixhawk and PX4 on Mac OS X (ver 10.6 onwards) with Make.

Note

The commands for building for the Pixhawk and Pixhawk2 are identical (make px4-v2). To build for Pixracer replace make px4-v2 with make px4-v4 in the instructions below. For the original (obsolete) PX4 use make px4-v1

  1. Install Homebrew for Mac OS X

  2. Install xcode and say YES to install Command Line Tools

    xcode-select --install
    
  3. Install the following packages using brew

    brew tap PX4/homebrew-px4
    brew update
    brew install genromfs
    brew install gcc-arm-none-eabi
    
  4. Install the latest version of awk using brew (make sure /usr/local/bin takes precedence in your path):

    brew install gawk
    
  5. Install pip and pyserial using the following commands:

    sudo easy_install pip
    sudo pip install pyserial future catkin_pkg empy
    
  6. Now create your directory and install all the software:

    mkdir -p px4
    cd px4
    git clone https://github.com/ArduPilot/ardupilot.git
    cd ardupilot
    git submodule update --init --recursive
    

    Note

    PX4Firmware,

    PX4NuttX and uavcan are automatically imported as Git Submodules when you build a vehicle.

  7. Choose a firmware type to build by entering a subdirectory; e.g.:

    cd ArduCopter
    
  8. Build the firmware by entering one of the following commands:

    make px4-v2 Build the Pixhawk2/Pixhawk firmware (identical) for a quad
    make px4-v2-hexa

    Build the Pixhawk firmware for a hexacopter.

    # Other supported suffixes include “octa”, “tri” and “heli”.

    # More can be found in “mk/tagets.mk” under FRAMES

    make px4 Build both PX4 and PixHawk firmware for a quadcopter
    make clean “clean” the ardupilot directory
    make px4-clean “clean” the PX4Firmware and PX4NuttX directories so the next build will completely rebuild them
    make px4-v2-upload Build and upload the Pixhawk firmware for a quad (i.e. no need to do step #7 below)

    The firmware will be created in the ArduCopter directory with the .px4 file extension, ready to load onto the Pixhawk. For example if you build for px4-v2, ArduCopter-v2.px4 will be created

  9. Occasionally you should pull PX4Firmware and PX4NuttX updates. To make sure it compiles correctly, run the clean option in make:

    make px4-clean
    make px4-[frame type]
    

    The available frame types are: quad, tri, hexa, y6, octa, octa-quad, hell.

  10. To make and upload to your vehicle do:

    make px4-quad-upload
