How to use PRINC

How to use PRINC

[Markus Hubig]

Hello @all,

now that I have found out that the variable "PRINC" stands for
"increment the PR-variable"
how do I use it?

Version 1, found here:
http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#using-bbappend-files

PRINC = "1"

Version 2, found here:
http://www.yoctoproject.org/docs/current/poky-ref-manual/poky-ref-manual.html#var-SRC_URI

PRINC := "${@int(PRINC) + 2}"

Cheers, Markus

This is the correct method to use in a bbappend. Start with 1,
obviously, and bump it each time the bbappend changes.

Scott, I believe this need updating in the dev-manual section "4.1.4.
Using .bbappend Files".
