make px4_sitl gazebo_typhoon_h480 fails after mavlink git version check

[Smashroom]

Heya,

I am trying to create a docker image that will let me build a ROS2+Gazebo+PX4 environment with DDS support.

Environment Docker image: px4io/px4-dev-ros2-galactic:latest PX4 commit: 1e93ae31482f6bdc64bc8120f5f2e5508dfef625 Gazebo installed via: curl -sSL http://get.gazebosim.org | sh MicroDDS agent installed via: https://github.com/micro-ROS/micro_ros_setup.git Python version: 3.8.10

To run the environment

docker run -it --privileged\
    --rm \
    --net=host \
    --env="DISPLAY=$DISPLAY" \
    --env="QT_X11_NO_MITSHM=1" \
    -v src/Firmware:/src/firmware/:rw \
    --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" \
    --env="XAUTHORITY=$XAUTH" \
    --volume="$XAUTH:$XAUTH" \
    --runtime=nvidia \
     image_name bash

Error:

build_git_version.h is not present:

cat: /src/firmware/build/px4_sitl_default/src/lib/version/build_git_version.h: No such file or directory

I couldn't get rid of the error whatever I tried. I didn't figure out a way to generate build_git_version.h. Did anyone faced that with the recent commits?

I have a similar issue and am still solving the issue.

I guess one reason is the newest version PX4-Autopilot change the setup_gazebo.bash location. Thus we have to change the bashrc file like this

source ~/px-ws/src/PX4-Autopilot/Tools/simulation/gazebo/setup_gazebo.bash ~/px-ws/src/PX4-Autopilot ~/px-ws/src/PX4-Autopilot/build/px4_sitl_default

I have same issue on docker image px4io/px4-dev-ros-noetic. Without mounting local PX4 src, I cloned repository in docker /home/user. After doing some installation steps, make px4_sitl gazebo-classic command shows following errors.

I think I found the reason. Previously, I installed PX4-Autopilot at /home/user. Maybe px4_update_git_header.py requires some certain directory.

After I removed the source code and re-installed at ~/, I successfully build with make px4_sitl gazebo-classic. It might not be correct reason but I didn't do any other stuff.
