Unable to run gazebo-classic simulation

PX4 Autopilot Simulation 🌍
1

It displays below error message when I try to run gazebo-classic simulation by make px4_sitl gazebo-classic.

ninja: error: unknown target 'gazebo-classic'
make: *** [Makefile:232: px4_sitl] Error 1
  1. Download PX4 Source Code:
git clone https://github.com/PX4/PX4-Autopilot.git --recursive
  1. Then, run the ubunth.sh:
bash ./PX4-Autopilot/Tools/setup/ubuntu.sh
  1. Run the gazebo-classic simulation:
make px4_sitl gazebo-classic

Thank you in advance!

@Masashi try running the following lines in your PX4-Autopilot directory:

make px4_sitl_default gazebo-classic

If that doesn’t solve it, try running:

make clean
make distclean

Now make the target. I have faced a similar issue in the past i.e., with gazebo as the deprecated target. Hope this helps!

Thank you for your reply!
I tried per your advice. However same error message is displayed…

4

It seems the latest PX4 code requires using “make px4_sitl gazebo-classic_iris”.
Try this.

Here’s another course you might want to consider: Delete the repository and restart the system. Clone and install it again from source. DO NOT forget to restart your system again.

Thanks for your help. I tried your proposal but the problem is not solved…

Hey Hi. I’m facing the similar issue. cant able to enable the actuators in HITL mode.

Thank you again for your help, Sidu!
I did try as follows:

  1. Delete the repository from my laptop
  2. Restart the laptop
  3. Clone the repo from the source:
git clone https://github.com/PX4/PX4-Autopilot.git --recursive
  1. Then, run the ubunth.sh:
bash ./PX4-Autopilot/Tools/setup/ubuntu.sh
  1. Restart the laptop again.
  2. Run the gazebo-classic:
make px4_sitl gazebo-classic

However, the problem is not solved. After that, I did clean and distclean build environment as you proposed, the error messages is still indicated.

make clean
make distclean

Run

make px4_sitl gazebo-classic_iris

Thank you for your help, Lim.

I fear you are using Ubuntu 22 with Gazebo Garden instead of Classic

12

what is the LINUX platform you are on .

13

Hi, thank you for your reply! Check results of my ubuntu version is attached below:

ubuntu_version

14

Hi, it is Ubuntu 20.04 as attached above.

15

Hi @Masashi , did you solve your issue?

16

No, it’s not solved yet.

17

Could you share the output of

./PX4-Autopilot/Tools/setup/ubuntu.sh

?

18

Hi ,
Kindly do a git checkout with px4 v1.13.3 inside the same folder as PX4-Autopilot .
Then do the ubuntu.sh and then make px4-sitl gazebo_classic_typhoon_H460 ( need to check the exact name for avoiding typo errors )

If you are using v1.13.3, then you need to use the documentation for v1.13:

For that version, the command to start the simulation is

make px4_sitl gazebo
