[poky] error while compiling hello_2.7.bb

[praveen vattipalli]

Hi Richard,
setting S = "${WORKDIR}/hello_2.7" or S = "${WORKDIR}"  didn't work. I used

in build/conf/local.conf

INHERIT += "externalsrc"
EXTERNALSRC_pn-hello =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"
EXTERNALSRC_BUILD_pn-hello =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"

in hello_2.7.bb

EXTERNALSRC =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"
EXTERNALSRC_BUILD =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"

now i could compile.

Thanks,
Praveen.
