[Bug] Error with running sims on Gazebo models: ninja: error: unknown target 'gz_x500' make: *** [Makefile:232: px4_sitl] Error 1

[ashishp166]

Describe the bug

I am trying to run make px4_sitl gz_x500 or make px4_sitl gz_x500_depth, but there seems to be an issue of ninja: error: unknown target 'gz_x500'. I have tried other models also and none of them seem to be working. I made sure to restart at all the spots mentioned on the official documentation for the setup of ROS2 with PX4 Autopilot.

3. (Restart the computer on completion)
4. make distclean
5. export CC=gcc
7. export CXX=g++
8. git submodule update --init --recursive

pip install symforce

[Noe-Sanchez]

That should fix it

[sanaosheng]

That should fix it

why my error is same to him completely,and I pip install symforce successfully,after that ,I try again ,but the error doesn't change.

[Collin-Emerson-Miller]

Same here, tried the pip install. No Dice.

[wangzy-dbug]

Did you solve this problem?i meet same sitiuation,and i installed symforce,but it changed nothing

[leechor]

I have the same problem

@ashishp166 @sanaosheng @Collin-Emerson-Miller @wangzy-dbug The problem may be caused due to running make distclean on the repo, or not having recursively cloned all submodules for simulation. Try doing git submodule update --init --recursive and try to build again. If the problem persists, try a new installation on the same machine.
