X-BeenThere: openembedded-core@lists.openembedded.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Patches and discussions about the oe-core layer List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 22 Jul 2014 16:36:22 -0000 Content-Type: TEXT/PLAIN; charset=US-ASCII quite possibly another silly question, but i'm perusing poky's version of bitbake.conf and i see this: DEPLOY_DIR ?= "${TMPDIR}/deploy" DEPLOY_DIR_TAR = "${DEPLOY_DIR}/tar" DEPLOY_DIR_IPK = "${DEPLOY_DIR}/ipk" DEPLOY_DIR_RPM = "${DEPLOY_DIR}/rpm" DEPLOY_DIR_DEB = "${DEPLOY_DIR}/deb" DEPLOY_DIR_IMAGE ?= "${DEPLOY_DIR}/images/${MACHINE}" DEPLOY_DIR_TOOLS = "${DEPLOY_DIR}/tools" now, what is the value of using "?=" to set DEPLOY_DIR_IMAGE, rather than just "=". i know what "?=" represents, but i normally expect to see it in a context where someone might have set it earlier to some other value, but this is in bitbake.conf, before any of the "include" or "require" directives to pull in any of the other .conf files. so in the midst of all those other DEPLOY_DIR_* hard assignments, why is the images directory a conditional install? rday -- ======================================================================== Robert P.
