%general-entities; ]> Linux-Headers For this step you will need the kernel tarball. Install the kernel header files: make mrproper make ARCH=arm headers_check make ARCH=arm INSTALL_HDR_PATH=dest headers_install cp -rv dest/include/* ${CLFS}/usr/include find ${CLFS}/usr/include -name .install -or -name ..install.cmd | xargs rm -fv make mrproper Ensures that the kernel source dir is clean. make ARCH=[arch] headers_check Sanitizes the raw kernel headers so that they can be used by userspace programs. make ARCH=[arch] INSTALL_HDR_PATH=dest headers_install Normally the headers_install target removes the entire destination directory (default /usr/include) before installing the headers. To prevent this, we tell the kernel to install the headers to a directory inside the source dir. Installed headers /usr/include/{asm,asm-generic,drm,linux,mtd,rdma,sound,video}/*.h Short Descriptions /usr/include/{asm,asm-generic,drm,linux,mtd,rdma,sound,video}/*.h The Linux API headers /usr/include/{asm,linux}/*.h
