6.5.2. Contents of Linux-Headers
Installed headers:
/usr/include/{asm,linux}/*.h
The Linux Headers package contains the “sanitized” kernel headers.
For years it has been common practice to use “raw” kernel headers (straight from a kernel
tarball) in /usr/include, but over
the last few years, the kernel developers have taken a strong
stance that this should not be done. This gave birth to the
Linux-Libc-Headers Project, which was designed to maintain an API
stable version of the Linux headers. Recently this project stopped
producing updates, so the Cross-LFS team started development on our
own project to sanitize the headers.
Install the header files that are common to all architectures:
install -dv ${CLFS}/usr/include
cp -av include/{asm-generic,linux,mtd,scsi,sound} ${CLFS}/usr/include
Install the header files that are specific to this architecture:
cp -av include/asm-i386 ${CLFS}/usr/include/asm
