    Hello,

    I'm following this guide https://docs.modalai.com/ros2-installation-voxl2/ to build the voxl-mpa-to-ros2 pkg and push it into VOXL2. I'm facing some problems with the instructions, in detail, I succeeded into creating the qrb5165-emulator image, then I can install the dependencies with './install_build_deps.sh qrb5165 dev', but when I try to run the build.sh file the voxl_msgs pkg fail to compile. Below the error I obtain. What am I doing wrong?

      @LR Hi going to look into this - for now can you just install the deb as is via apt-get install voxl-mpa-to-ros2 ?

      Will let you know if I run into the same error.

        This is the same build error I ran into (see here https://forum.modalai.com/topic/3908/voxl-px4-and-voxl-mpa-to-ros2-message-compatibility-and-build-issues)

        It turned out to be a issue with the version of empy installed when running install_build_dependencies (specifically in python3 -m pip install colcon-common-extensions lark)

        I resolved it by downgrading empy after running the install build dependencies script in the docker container

        python3 -m pip uninstall -y empy
        python3 -m pip install empy==3.3.4

          Yep @jmltt @LR I merged in an MR this morning that will capture this error for empy not being compatible - thanks for the find @jmltt !!!

            @Zachary-Lowell-0 Hi, thank you for your response! I've tried to installed it directly but when I try to access it with ros2 run voxl_mpa_to_ros2 voxl_mpa_to_ros2 it doesn't find the node, I also checked under opt/ros/foxy/mpa_to_ros2/install and the package is not there...support3.png
            I tried again to install it on the docker container with what @jmltt told me and now I have this problem
            support4.png
            Lastly I tried also to install voxl_mpa_to_ros for melodic but in this case the package contains just the launch file and not the voxl_mpa_to_ros_node so again I cannot call the function
            support5.png

            Sorry for all this...

                @LR I removed and reinstalled voxl-mpa-to-ros2 and that is working now, for voxl-mpa-to-ros I still have the same problem
