5.4.2. Contents of Linux-Headers
Installed headers:
/usr/include/{asm,asm-generic,drm,linux,mtd,rdma,sound,video}/*.h
The Linux Kernel contains a make target that installs “sanitized” kernel headers.
For this step you will need the kernel tarball.
Install the kernel header files:
make mrproper
make ARCH=x86 headers_check
make ARCH=x86 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
The meaning of the make commands:
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.
