#!/bin/bash
#
# Find a native sysroot to use - either from an in-tree Poky build or
# from a toolchain installation in /opt/poky. It then sets the variables
# $NATIVE_SYSROOT_DIR to the sysroot's base directory, $PSEUDO to the
# path of the pseudo binary, and $SYSROOT_MODE is set to "in-tree" or
# "toolchain".
#
# This script is intended to be run within other scripts by source'ing
# it, e.g:
#
# SYSROOT_SETUP_SCRIPT=`which poky-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.
