5.5.1. Installation of Linux API 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=dest headers_install
cp -rv dest/include/* /tools/include

Details on this package are located in Section 6.7.2, “Contents of Linux API Headers.”
