While normally not possible on embedded platforms, it is possible to build kernels on your Raspberry Pi with its luxurious root file system. Despite this, cross-compiling on desktop systems is often preferred for faster compile times. This chapter examines the procedure for building your Raspbian kernel outside of the Pi.

It is assumed that you have the cross-compiler tools and environment ready. Either the tool set built in Chapter 20 or an installed prebuilt tool chain will do. In this chapter, I assume that the cross-compiler prefix is as follows (ending in a hyphen):
