Even w/o multiconfig, this will break for multi-machine builds. Native packages are for the build host and have no knowledge about the target. You should probably look into cross packages instead of native ones for this use case. Altering native packages between different targets will cause them to rebuild, which they shouldn't. Moreover, it will mess up your sstate and lead to weird issues down the road when trying to re-use your sstate mirror/cache. > >and this requirement is no longer met. > >Many of these anomalies can be verified with the use of the rm_work and > >create-spdx bitbake classes. > > > >A previous attempt [1] had already been made but was refused > >but this way it can be done without side effects for other users. > > > >[1] https://lists.yoctoproject.org/g/meta-ti/message/14767 > > > So the difference between this patch and the previous one, is that > you are now included a file that is not there normally so that you > can put the contents of the previous patch in the new include file > to get around the issue in the archiver. > > I'm not saying I'm opposed to this approach (yet), I'm just trying > to understand the entire story. > > Did you find anything in looking at fixing the archiver to better > support the multi-config issue? > > > > >Signed-off-by: Jose Quaresma <jose.quare...@foundries.io> > >--- > > meta-ti-bsp/conf/multiconfig/k3r5.conf | 2 ++ > > 1 file changed, 2 insertions(+) > > > >diff --git a/meta-ti-bsp/conf/multiconfig/k3r5.conf > >b/meta-ti-bsp/conf/multiconfig/k3r5.conf > >index deb07210..b69c5d6d 100644 > >--- a/meta-ti-bsp/conf/multiconfig/k3r5.conf > >+++ b/meta-ti-bsp/conf/multiconfig/k3r5.conf > >@@ -3,3 +3,5 @@ MAINMACHINE := "${MACHINE}" > > DEPLOY_DIR_IMAGE = "${DEPLOY_DIR}/images/${MAINMACHINE}" > > MACHINE:append = "-k3r5" > >+ > >+include conf/multiconfig/k3r5.inc
