| Here's how to cross-build the kernel from the git repository. == Initial setup == Having ccache installed is optional but helpful if you are often rebuilding the package from scratch with minor modifications. $sudo apt-get install gcc-arm-linux-gnueabihf ccache Get the source $git clone git://kernel.ubuntu.com/jani/ubuntu-nexus7.git == Rebuild the package == $cd ubuntu-nexus7 $git clean -xdf You may want to do this to disable cross-building of the linux-tools binary package, as that requires multiarch setup and some armhf libs installed in the host system. $sed -i '/do_tools/ s/true/false/' debian.linaro/rules.d/armhf.mk $fdr clean (fdr is the shell alias for fakeroot debian/rules, useful as it is typed quite often while working with the kernel package) $debuild -eDEB_BUILD_OPTIONS="parallel=3" -eCROSS_COMPILE="ccache arm-linux-gnueabihf-" -b -aarmhf -us -uc -nc == Build zImage only == Sometimes you just want a zImage for a quick test such as inserting it in a boot.img and trying it out without a full deb installation. This does an out of source tree build of a zImage (no modules) using the current Ubuntu configs $cd ubuntu-nexus7 $mkdir ../build $cp debian.linaro/config/config.common.ubuntu ../build/.config $CROSS_COMPILE="ccache arm-linux-gnueabihf-" ARCH=arm make O=../build -j 8 zImage In the above snippets -j and parallel= are obviously to be adjusted depending on need. |
