I tried the command make posix\_sitl\_default jmavsim on Mac, but it doesn’t work. (I think I have followed everything on the instruction). Please tell me what’s going on here.

+1 I have the same errors on Mac OSX too when I run the command If it helps I have been using gazebo instead of jmavsim. make posix\_sitl\_default gazebo\_standard\_vtol ---

Hello, I am having the same issue, I am having the same issue, and was wondering if there someone had found a fix for it? I am following the tutorial found here [https://dev.px4.io/en/setup/building\_px4.html](https://dev.px4.io/en/setup/building_px4.html) And when I run “make posix jmavsim” The same error comes up: “Error: Unable to access jarflie jmavsim\_run.jar” If anyone can help I would greatly appreciate it, I am running on 14.04 Ubuntu. The full output is below: ``` >:~/snapdragon/Firmware$ make posix jmavsim [0%] [0%] Built target prebuild_targets Built target git_gencpp [0%] [0%] Built target lib__micro-CDR Built target git_genmsg
