Honestly, I don't *THINK* it will be necessary to use a cross-compiler to build a 64-bit kernel, but then again, I've never personally built a kernel on a system that wasn't already 64-bit capable - perhaps Ryan or Matt could speak up more on this. But, the kernel compilation is pretty well self-contained, not requiring anything else to complete properly, and therefore it may very well be possible to use a 32-bit GCC. But, you could of course use your shiny new Cross-GCC to build the kernel using make ARCH=x86_64 menuconfig and so on. HTH, Jeremy
Once you've booted into your 64bit temp system using the boot method, you can use the toolchain compiler that was built with your cross-compiler in the earlier chapter. There is no need to cross-compile.
