Hello guys, I want to build virtualbox using this guide: https://habr.com/ru/post/447300/
However after the first kmk command I get this message:
"failed to mark [path] as volatile" (attachment 1)
No errors so far but when I run the second kmk command I get a lot of errors with code LGHT0103.
Here are screenshoots of first kmk:

Does anyone know how to fix these issues and get it to work? What am I doing wrong?

Most Windows users don't build Virtualbox, so this one might take a while to answer. See this tutorial from the developers: https://www.virtualbox.org/wiki/Windows ... structions
