Some bug problem from using Gazebo to simulate PX4 models

Question

I am trying to use gazebo to simulate the PX4 model. I have followed the steps on the official website from PX4. But I keep encountering this issue. When i try to run the instruction " make px4_sitl gz_x500" the system will tell me that { error: unknown target 'gz_x500' } I do not know how to solve it!

i hope that someone could help me to figure out.

Answer 1

try this in Terminal sudo apt-get install gz-garden

Answer 2

As documentation suggests,

If make px4_sitl gz_x500 gives the error ninja: error: unknown target 'gz_x500' then run make distclean to start from a clean slate, and try running make px4_sitl gz_x500 again.
