import-layers/yocto-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.
