poky/scripts/oe-find-native-sysroot

#!/bin/bash

Find a native sysroot to use - either from an in-tree OE build or

from a toolchain installation. It then ensures the variable

$OECORE_NATIVE_SYSROOT is set to the sysroot's base directory, and sets

$PSEUDO to the path of the pseudo binary.

This script is intended to be run within other scripts by source'ing

it, e.g:

SYSROOT_SETUP_SCRIPT=which oe-find-native-sysroot

. $SYSROOT_SETUP_SCRIPT

This script will terminate execution of your calling program unless

you set a variable $SKIP_STRICT_SYSROOT_CHECK to a non-empty string

beforehand.
