Dexuan Cui be2a2764d8 oe-init-build-env, scripts/oe-buildenv-internal: add error detecting for $BDIR
[YOCTO #671]

"readlink -f" in Ubuntu 10.04 is buggy: it doesn't ignore a trailing / (e.g.,
"readlink -f /tmp/non-existent-dir/" returns nothing, but according to
http://www.gnu.org/s/coreutils/manual/coreutils.pdf it should do that --
hence we get bug 671. It seems Ubuntu 10.10 or even later Ubuntu 11.04,
and other Linux distributions(e.g., Open Suse 11.4) haven't such an issue.

So I think we should detect this and ask Ubuntu 10.04 users to avoid supply
a path with trailing slash here.

Moreever, I also add the detection of non-existent path, e.g.,
source oe-init-build-env /non-existent-dir/build
can be detected and we'll print an error msg.
And, if we get errors in oe-buildenv-internal, we should stop the script
and shouldn't further run.

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 [ -z "$ZSH_NAME" ] && [ "x$0" = "x./oe-init-build-env" ]; then echo "Error: This script needs to be sourced. Please run as '. ./oe-init-build-env'" else if [ -n "$BASH_SOURCE" ]; then OEROOT="dirname $BASH_SOURCE" else OEROOT="pwd" fi OEROOT=readlink -f "$OEROOT" export OEROOT . $OEROOT/scripts/oe-buildenv-internal &&
$OEROOT/scripts/oe-setup-builddir &&
[ -n "$BUILDDIR" ] && cd $BUILDDIR unset OEROOT unset BBPATH fi
