I'm testing a new board with a BSP that is setup on the gatesgarth branch. I've been able to build and load the demo images for this board. I'm now trying to use multiconfig to build images for my old board and my new board. So far the build hasn't got past parsing recipes and I'm wondering what I'm doing wrong.For my setup, I have two separate layers for the two different boards. Each layer has its own MACHINE and DISTRO definitions. I setup the multiconfig files as follows: conf/local.conf: Added the following line: BBMULTICONFIG = "configA configB" conf/multiconfig/configA.conf: (config for old board) MACHINE = "machineA" TMPDIR = "${TOPDIR}/tmpConfigA" DISTRO = "distroA" conf/multiconfig/configB.conf: (config for new board) MACHINE = "machineB" TMPDIR = "${TOPDIR}/tmpConfigB" DISTRO = "distroB" If I try building the old image by doing: bitbake mc:configA:image-nameA I get errors while parsing the files. It complains about a Network Manager bbappend in layer B that uses variables that depends on MACHINE being set to "machineB". The image for configA does not use Network Manager. I also tried removing the MACHINE and DISTRO settings from local.conf to make sure the multiconfig settings are used, but then I get an error that MACHINE has not been set. Does layerB need something added to it so parsing ignores recipes in this layer when they aren't needed? Or do the recipes need to change so they build for other machines?
When you use multiconfig, all of you layers need to parse for all configurations (although this is generally good layer practice in general, not just when using multiconfig). Usually this involves writing the recipes to use overrides where appropriate
Although, if you _really_ don't want to do that, the BBMASK variable (https://docs.yoctoproject.org/ref-manual/variables.html#term-BBMASK) can now be set per-multiconfig so you can have layerA mask out layerB recipes and vice-versa.
Thanks, Bryan
