When building the SDK on Arch Linux with gcc 12.2.0 I'm getting these errors which did not occur on 3.7.6:

@cbix Did you try to add this include #include <limits>?

[rehans]

I have just built on Manjaro with gcc 12.2 and indeed it fails because of the missing header.

[ygrabit]

ok, thanks we will add it in the next SDK update
