It is assumed OEROOT is already defined when this is called

if [ -z "$OEROOT" ]; then echo >&2 "Error: OEROOT is not defined!" return 1 fi

if [ -z "$OE_SKIP_SDK_CHECK" ] && [ -n "$OECORE_SDK_VERSION" ]; then echo >&2 "Error: The OE SDK/ADT was detected as already being present in this shell environment. Please use a clean shell when sourcing this environment script." return 1 fi

Make sure we're not using python v3.x. This check can't go into

sanity.bbclass because bitbake's source code doesn't even pass

parsing stage when used with python v3, so we catch it here so we

can offer a meaningful error message.

py_v3_check=$(/usr/bin/env python --version 2>&1 | grep "Python 3") if [ -n "$py_v3_check" ]; then echo >&2 "Bitbake is not compatible with python v3" echo >&2 "Please set up python v2 as your default python interpreter" return 1 fi unset py_v3_check

Similarly, we now have code that doesn't parse correctly with older

versions of Python, and rather than fixing that and being eternally

vigilant for any other new feature use, just check the version here.

py_v26_check=$(python -c 'import sys; print sys.version_info >= (2,7,3)') if [ "$py_v26_check" != "True" ]; then echo >&2 "BitBake requires Python 2.7.3 or later" return 1 fi unset py_v26_check

if [ -z "$BDIR" ]; then if [ -z "$1" ]; then BDIR="build" else BDIR="$1" if [ "$BDIR" = "/" ]; then echo >&2 "Error: / is not supported as a build directory." return 1 fi

    # Remove any possible trailing slashes. This is used to work around
    # buggy readlink in Ubuntu 10.04 that doesn't ignore trailing slashes
    # and hence "readlink -f new_dir_to_be_created/" returns empty.
    BDIR=$(echo $BDIR | sed -re 's|/+$||')

    BDIR=$(readlink -f "$BDIR")
    if [ -z "$BDIR" ]; then
        PARENTDIR=$(dirname "$1")
        echo >&2 "Error: the directory $PARENTDIR does not exist?"
        return 1

if [ -n "$2" ]; then
    BITBAKEDIR="$2"

if [ -z "$BITBAKEDIR" ]; then BITBAKEDIR="$OEROOT/bitbake$BBEXTRA" fi

BITBAKEDIR=$(readlink -f "$BITBAKEDIR") BUILDDIR=$(readlink -f "$BUILDDIR")

if [ ! -d "$BITBAKEDIR" ]; then echo >&2 "Error: The bitbake directory ($BITBAKEDIR) does not exist! Please ensure a copy of bitbake exists at this location" return 1 fi
