There is a howto on building a kernel:


but that's pretty old (though might of course work still). Fortunately
there shouldn't be anything funny about building it. I usually take
these steps (inside scratchbox) without problems:

 - Get the sources with 'apt-get source kernel-source-rx-34'
 - configure with the default config for N800 with 'make n800_defconfig'
 - tweak the config with 'make menuconfig HOSTCC=host-gcc'
 - build the image with 'make HOSTCC=host-gcc'
 - flash the resulting image or just boot with it without flashing
   (see flasher docs for how)
 - (optionally build modules too and install them inside scratchbox,
you need to deploy them manually to the device though)

I'm not sure if the HOSTCC is needed for 'make', but make menuconfig
most likely needs it (to find ncurses).

Yes, see
