In fact we are not planning on supporting out of tree kernel builds, but rather to support out of tree build for all packages in a generic way, which would include the 'linux' package of course. I did some work in this area many years ago, Yann picked up some of the work, see the current status at https://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/oot. I see he has other "oot" branches, such as https://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/oot-build-dir, https://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/oot-libtool and https://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/oot-same-source. I'm not sure how they relate to each other (I haven't looked at the patches). Best regards, Thomas -- Thomas Petazzoni, CTO, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
