Cross compile - CROSS_OPSYS_VERSION usage / syntax ?

[vom513 <vom513%gmail.com@localhost>]

Hello all,

I;m doing some cross compiles, and was wondering about the CROSS_OPSYS_VERSION variable ?  I have:

CROSS_OS_VERSION= 10.1
CROSS_OPSYS_VERSION= 100100

In mk.conf.  Those two variables seem a bit redundant maybe ?  

What does CROSS_OPSYS_VERSION do as opposed to the OS_VERSION ?

Also is the syntax xxyyzz - so for 10.1 it’s 100100 ?

Thanks.
