環境変数設定

ビルド前に設定ファイルと、環境変数の設定が必要である。

環境変数保存ファイル"source.txt"（我が家の環境変数の抜粋）

BBPATH=${HOME}/oz/:${HOME}/oz/build/:${HOME}/oz/org.openembedded.stable/
PKGDIR=${HOME}/oz/build/
DL_DIR=${HOME}/oz/downloads 
echo Setting up dev env for ngström
if [ -z ${ORG_PATH} ]
then
ORG_PATH=${PATH}
export ORG_PATH
fi
if [ -z ${ORG_LD_LIBRARY_PATH} ]
then
ORG_LD_LIBRARY_PATH=${LD_LIBRARY_PATH}
export ORG_LD_LIBRARY_PATH

cd $PKGDIR LD_LIBRARY_PATH=
export PATH LD_LIBRARY_PATH BBPATH
