i know, but if i do this with the source example i'm playing with:
EXTERNALSRC = "${THISDIR}/src"
# EXTERNALSRC_BUILD = "${EXTERNALSRC}"
and let EXTERNALSRC_BUILD default to the value you identify, i get:
| make: *** No rule to make target 'install'. Stop.
i clearly don't understand something fundamental about using
externalsrc -- how do i get that external, remote source to build
under WORKDIR?
