Gary Thomas 61e8fdba04 oe-init-build-env: Improve script sourcing detection.

This script is only useful when sourced into a shell.
These changes improve the detection of this operation,
no matter how the script is referenced.

Normally this is called as '. ./oe-init-build-env builddir'

This works in most shells (not dash), but not all of them pass arg1 when

being sourced. To workaround the shell limitation use "set arg1" prior

to sourcing this script.

if [ -n "$BASH_SOURCE" ]; then OEROOT="dirname $BASH_SOURCE" elif [ -n "$ZSH_NAME" ]; then OEROOT="dirname $0" else OEROOT="pwd" fi if [ -n "$BBSERVER" ]; then unset BBSERVER fi THIS_SCRIPT=$OEROOT/oe-init-build-env

if [ -z "$ZSH_NAME" ] && [ "$0" = "$THIS_SCRIPT" ]; then echo "Error: This script needs to be sourced. Please run as '. $THIS_SCRIPT'" exit 1 fi

OEROOT=readlink -f "$OEROOT" export OEROOT . $OEROOT/scripts/oe-buildenv-internal &&
$OEROOT/scripts/oe-setup-builddir &&
[ -n "$BUILDDIR" ] && cd $BUILDDIR unset OEROOT unset BBPATH unset THIS_SCRIPT

Shutdown any bitbake server if the BBSERVER variable is not set

if [ -z "$BBSERVER" ] && [ -f bitbake.lock ] ; then grep ":" bitbake.lock > /dev/null && BBSERVER=cat bitbake.lock bitbake --status-only if [ $? = 0 ] ; then echo "Shutting down bitbake memory resident server with bitbake -m" BBSERVER=cat bitbake.lock bitbake -m fi fi
