[Bug] ninja: error: unknown target 'gz_x500' when installing PX4 Simulator

idorobotics commented 1 year ago

Describe the bug

Following the latest PX4 Gazebo Simulation instructions installs Gazebo Garden but the PX4 simulator cannot be run. The error when running make px4_sitl gz_x500 is ninja: error: unknown target 'gz_x500'. The error is the same for all available models.

ROS 2 works fine on its own. Gazebo Garden also works fine on its own.

Performing a make clean on PX4 Autopilot and running the install script and make does not solve the problem.

To Reproduce

Installed PX4 (main branch) and ROS 2 humble using the steps here: https://docs.px4.io/main/en/ros/ros2_comm.html#humble
Installed Gazebo Garden using the steps here: https://docs.px4.io/main/en/sim_gazebo_gz/
run make px4_sitl gz_x500 and the output is ninja: error: unknown target 'gz_x500'
run make --trace px4_sitl gz_x500 (output below)

Makefile:232: target 'px4_sitl' does not exist
# check if the desired cmake configuration matches the cache then CMAKE_CACHE_CHECK stays empty
# change to build folder which fails if it doesn't exist and CACHED_CMAKE_OPTIONS stays empty
# fetch all previously configured and cached options from the build folder and transform them into the OPTION=VALUE format without type (e.g. :BOOL)
# transform the options in CMAKE_ARGS into the OPTION=VALUE format without -D
# find each currently desired option in the already cached ones making sure the complete configured string value is the same
# if the complete list of desired options is found in the list of verified options we don't need to reconfigure and CMAKE_CACHE_CHECK stays empty
# make sure to start from scratch when switching from GNU Make to Ninja
if [ Ninja = "Ninja" ] && [ -e "~/PX4_software/PX4-Autopilot/build/px4_sitl_default"/Makefile ]; then rm -rf "~/PX4_software/PX4-Autopilot/build/px4_sitl_default"; fi
# make sure to start from scratch if ninja build file is missing
if [ Ninja = "Ninja" ] && [ ! -f "~/PX4_software/PX4-Autopilot/build/px4_sitl_default"/build.ninja ]; then rm -rf "~/PX4_software/PX4-Autopilot/build/px4_sitl_default"; fi
# only excplicitly configure the first build, if cache file already exists the makefile will rerun cmake automatically if necessary
if [ ! -e "~/PX4_software/PX4-Autopilot/build/px4_sitl_default"/CMakeCache.txt ] || [  ]; then mkdir -p "~/PX4_software/PX4-Autopilot/build/px4_sitl_default" && cd "~/PX4_software/PX4-Autopilot/build/px4_sitl_default" && cmake "~/PX4_software/PX4-Autopilot" -G"Ninja" -DCONFIG=px4_sitl_default || (rm -rf "~/PX4_software/PX4-Autopilot/build/px4_sitl_default"); fi
# run the build for the specified target
cmake --build "~/PX4_software/PX4-Autopilot/build/px4_sitl_default" --  gz_x500
ninja: error: unknown target 'gz_x500'
make: *** [Makefile:232: px4_sitl] Error 1

Can you give this a try?

first reboot if you haven't since installing gazebo
start from a clean state (make distclean)
run make px4_sitl gz_x500 and share the full output

Worked well, thanks! I think the issue was that following the instructions to first set up ROS 2 requires running make px4_sitl but the Gazebo setup instructions expect you to run make px4_sitl gz_x500 instead.

why I can run "make px4_sitl"seccessfully,but then failed to run "make px4_sitl gz_x500" anyway.
