Creating kernel header/include files

Sometimes when cross-compiling a kernel, the host machine requires the header files to compile programs locally.

To create them, go to your kernel source and:

make headers_install INSTALL_HDR_PATH=/destination

For example:

mkdir /tmp/header
make headers_install ARCH=arm INSTALL_HDR_PATH=/tmp/header

More information is available at your_kernel_source/Documentation/make/headers_install.txt
