PX4/JMAVSIM Build Error (return value 512)

[KrystekT]

Hi,
I am trying to run JMAVSIM on Windows 10. It worked for me before and then something happened when I tried to run it again. I uninstalled and reinstalled the PX4 Toolchain and have tried to run it again and keep getting this error. I have look at some stuff that it has something to do with bash, dash, but I don't understand the lingo I'm pretty new to this. Here is the run error:

@KrystekT Generally best to raise first in PX4 slack #issues channel- more eyes there. They will then tell you if there is a bug and point you to right place to post. This is a docs repo, and what you have here is some problem with code, not the docs - so I am closing.

That said, @MaEtUgR FYI - in case you have seen this before.

This is a known issue that came in with the NuttX upgrade and has to be solved soon but is not yet. See PX4/PX4-Autopilot#15795, PX4/PX4-Autopilot#15139 (comment)
