Issue building code for pixhawk

Posted by Mark Agate on April 14, 2015 at 12:41pm

Hello,

I am trying to build a custom arduplane code for the pixhawk using the make px4 command and the px4-toolchain. I am getting an error in the toolchain:

On Windows please run:

  easy_install empy catkin_pkg

I tried deleting and redownloading the ardupilot, PX4Firmware, and PX4NuttX from GitHub several times and it didn't fix the problem.

Has anyone encountered this before?

Thanks.

    I solved this problem in the following way:

    1) download the source of "genmsg" from https://github.com/ros/genmsg -> find inside the folder "genmsg" -> copy it into {path to your python installation}\Lib
    2) download the source of "catkin" from https://github.com/ros/catkin -> find inside the folder "catkin_pkg" -> copy it into {path to your python installation}\Lib
    3) download the source of empy from http://www.alcyone.com/software/empy/empy-latest.tar.gz ->
    find inside the file "em.py" -> copy it into {px4 folder}\Tools
    4) launch your python and make sure that the following commands work:

    import em
    import genmsg

    I hope this will help you..
