PX4 SITL Build Error: "No rule to make target 'px4_sitl'"

PX4 Autopilot
1

I am beginner in drone simulation field for PX4

I already downloaded gazebo, (not from PX4 document), and I was trying to apply the first command in this page
but unfortunately, I face this result:
make: *** No rule to make target 'px4_sitl'. Stop.

What is the reason, and how to solve this?

Hi there!

Try make px4_sitl gz_x500

In general, if you do not follow the official setup, your are on your own.

Also double check you have gazebo installed
