From 68a8caa738caa25f313a0bccfd8179cc5584afa5 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Fri, 22 Jun 2012 17:44:10 -0700 Subject: kernel: Add kernel headers to kernel-dev package [YOCTO #1614] Add the kernel headers to the kernel-dev package. This packages what was already built and kept in sysroots for building modules with bitbake. Making this available on the target requires removing some additional host binaries. Move the location to /usr/src/kernel Before use on the target, the user will need to: # cd /usr/src/kernel # make scripts This renders the kernel-misc recipe empty, so remove it. As we use /usr/src/kernel in several places (and I missed one in the previous version), add a KERNEL_SRC_DIR variable and use that throughout the class to avoid update errors in the future. Now that we package the kernel headers, drop the kernel_package_preprocess function which removed them from PKGD. All *-sdk image recipes include dev-pkgs, so the kernel-dev package will be installed by default on all such images.
