Bizarre Build Errors w/v1.6.5 on Windows Creator Ubuntu 16.04 bash

1

My build for v1.6.5 used to work flawlessly. Since I updated to Windows10 Creators edition and re-installed the linux shell support (Ubuntu 16.04.02) I’m been getting strange errors when making the px4fmu-v2_default target:

Anyone have this issue before and know the configuration fix for it??
Thanks

Seems that my …\Firmware\build_px4fmu-v2_default\external\Install\include is empty of files which I presume is why the errors are occurring. Anyone know the stage where these are moved over to the build folder?

Ok - that folder seems to be left empty regardless. On my other machine that folder is empty unless it is cleaned up after a build happens…

On subsequent makes, there is a different error in a different module. If I just retry building the firmware it eventually succeeds - at least the errors stop showing up.

I even try just to build all platforms and I get a strange error.
