%general-entities; ]> Linux-Headers The Linux kernel needs to expose an Application Programming Interface (API) for the system's C library (Glibc in LFS) to utilize. This is done by way of sanitizing various C header files that are shipped in the Linux kernel source tarball. Install the header files: make mrproper make headers_check make INSTALL_HDR_PATH=/usr headers_install Ensure that all the headers are owned by root: chown -Rv root:root /usr/include/{asm,linux} Make sure the users can read the headers: find /usr/include/{asm,linux} -type d -exec chmod -v 755 {} \; find /usr/include/{asm,linux} -type f -exec chmod -v 644 {} \; Installed headers /usr/include/{asm,linux}/*.h Short Descriptions /usr/include/{asm,linux}/*.h The Linux API headers /usr/include/{asm,linux}/*.h
