poky/scripts/bitbake

#!/bin/sh

This is the bitbake wrapper script that ensures everything is set up

correctly in the environment, builds pseudo separately if it hasn't

already been built, and then runs bitbake within pseudo.

export BBFETCH2=True export BB_ENV_EXTRAWHITE="PSEUDO_BUILD PSEUDO_DISABLED $BB_ENV_EXTRAWHITE"

For certain operations (i.e. that won't be actually running any tasks)

we don't need pseudo

NO_BUILD_OPTS="--version -h --help -p --parse-only -s --show-versions -e --environment -g --graphviz"

Some options are useful to pass through to the initial pseudo build if

that needs to be run (for debugging)

PASSTHROUGH_OPTS="-D -DD -DDD -DDDD -v"

needpseudo="1" for opt in $@; do for key in $NO_BUILD_OPTS; do if [ $opt = $key ] then needpseudo="0" break fi done [ $needpseudo = "0" ] && break done

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 [ "$py_v3_check" != "" ]; then echo "Bitbake is not compatible with python v3" echo "Please set up python v2 as your default python interpreter" exit 1 fi

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 >= (2,6,0)' if [ "$py_v26_check" != "True" ]; then echo "BitBake requires Python 2.6 or later" exit 1 fi

if [ ! -e conf/bblayers.conf ] ; then BDPRINT="" [ -n "$BUILDDIR" ] && BDPRINT=": $BUILDDIR" echo "Unable to find conf/bblayers.conf" echo "BitBake must be run from within your build directory$BDPRINT" exit 1 elif [ -z "$BUILDDIR" ] ; then BUILDDIR="pwd" fi

needtar="1" TARVERSION=tar --version | head -n 1 | cut -d ' ' -f 4 float_test() { echo | awk 'END { exit ( !( '"$1"')); }' }

Tar version 1.24 and onwards handle overwriting symlinks correctly

but earlier versions do not; this needs to work properly for sstate

float_test "$TARVERSION > 1.23" && needtar="0"

buildpseudo="1" if [ $needpseudo = "1" ]; then if [ -e "$BUILDDIR/pseudodone" ]; then PSEUDOBINDIR=cat $BUILDDIR/pseudodone else PSEUDOBINDIR=bitbake -e | grep STAGING_BINDIR_NATIVE=\" | cut -d '=' -f2 | cut -d '"' -f2 fi if [ -e "$PSEUDOBINDIR/pseudo" ]; then buildpseudo="0" fi

# Verify that the pseudo recipes are older then the pseudodone file
PSEUDO_RECIPE="`dirname $0`/../meta/recipes-devtools/pseudo"
if [ $buildpseudo -eq 0 ] && [ ! -d "$PSEUDO_RECIPE" ]; then
    echo "Unable to verify if pseudo-native is up to date..." >&2
elif [ $buildpseudo -eq 0 ]; then
PSEUDO_NEWER=`find $PSEUDO_RECIPE -type f -newer $BUILDDIR/pseudodone`
if [ -n "$PSEUDO_NEWER" ]; then
        buildpseudo="2"
fi
fi
if [ $buildpseudo = "0" -a ! -e "$BUILDDIR/pseudodone" ] ; then
    echo $PSEUDOBINDIR > $BUILDDIR/pseudodone
fi

fi

If tar is already built, we don't want to do it again...

if [ -e "$PSEUDOBINDIR/tar" -a "$needtar" = "1" ]; then needtar="0" fi

if [ $needpseudo = "0" ]; then buildpseudo="0" fi

If pseudo-native is an argument, assume the user wants to build pseudo-native!

if [ $needpseudo != "0" -a $buildpseudo -eq 0 ]; then for opt in $@; do if [ "$opt" = "pseudo-native" ]; then buildpseudo="3" break fi done fi
