Make posix jmavsim failed

Hi all,

I am new to using the px4 stack and I have been working my way through the installation tutorial. I have tried to run the cmd ‘make posix jmavsim’, it seems to work fine but I do not get the terminal back and thus cannot send commands to the drone.

I posted the output of the command below. I see the line WARN [simulator] bind failed which seems to indicate some failure.

I would appreciate any help,

thanks
