Please suggest a work around for the pc hangup when run the command

make px4_sitl gazebo

-- computer freezes when doing this -- I have to press the power button to restart.

I am trying to simulate a plane in gazebo and work with the mavsdk libraries.
If this issue is still new, then I do have a pixhawk with which I can start HITL directly. But would need the steps to run mavsdk c++ file to run a mission on QGC and Xplane10.

Would be grateful to whoever is able to help me here.!

Thanks,
Prasheel

Update:
So, I had been SMH for quite a few days on this, and finally got it to work!
I commented every dependency in the CMakeLists of sitl_gazebo. Somehow with all at once, the plugins do not work. I worked them out one by one.
But, there are some serious issues in usv_dynamics plugin as thats the last part in the commented part with which the issue still exists!. Also, had to first build on px4_sitl_default gazebo then worked it out on gazebo_plane. This finally got the model running with mission commands from QGC.
But, did give these errors-

cc1plus: warning: unrecognized command line option ‘-Wno-address-of-packed-member’

I believe there are some issues with the build as it does not let me take all these plugins at once. I specially upgraded to gazebo9 for this (compromised my work on turtlebot - doesnt work on g9). The memory taken up at runtime is huge that causes the machine to freeze? I would be happy to work it out with you guys! But for now the issue is resolved (except the error log from eigen, which disappears on successive runs). I hope there are no dependencies on the usv_dynamics plugin.

Please do let me know how I can be of any help guys!.

Thanks,
Prasheel

-- computer freezes when doing this -- I have to press the power button to restart.

I guess it's your computer running out of RAM during linking.

This is a warning, so you should be able to get around it by disabling -Werror.

I am using an 8GB RAM with >50GB free space on my hard drive. I have an NVIDIA GPU.
I would be happy to know the requirements to run the firmware?

RAM usage depends on your CPU threads (compiler jobs), usually need 2GB per job.

Well, I wonder how this same firmware works well on a Pixhawk2 (currently using for HITL).
Please mind my knowledge in the field, kind of a rookie in flying drones but I'm good with C++!

Anyway, great to know about this. Would definitely take a look at the source code.

Thank you for the insight.

With #14971 you can now build with fewer cores in order to avoid running out of RAM:

make px4_sitl gazebo -j2
