You're missing the basic libraries for native compilation.

Thanks, I feel like a real idiot. Somehow a bunch of development packages
(libc6-dev, ncurses5-dev, and a few others) got uninstalled on that
Anyway... I was somewhat able to cross-compile a kernel.
Shiva:/usr/src/linux-22.214.171.124# file vmlinux
vmlinux: ELF 64-bit MSB executable, MIPS, MIPS-IV version 1 (SYSV),
statically linked, not stripped
However, when I rsync it over to my O2, it does not boot. It panics almost
immediately, like all other kernels I compiled natively (on the O2) from
something other than the Debian sources. This is the full panic as
displayed from the PROM:

Just to make sure I'm not doing something stupid. Here are the command in
my kernel build sequence:
make CROSS_COMPILE=mips-linux-gnu- oldconfig
make -j 3 CROSS_COMPILE=mips-linux-gnu- all
make CROSS_COMPILE=mips-linux-gnu- INSTALL_MOD_PATH=~/ modules_install
cp vmlinux ~/boot/vmlinux-126.96.36.199
cp System.map ~/boot/System.map-188.8.131.52
cp .config ~/boot/config-184.108.40.206
tar -cf kernel.tar lib boot
CONFIG_CROSSCOMPILE=y in my .config.
I also tried rsyncing the Debian sources over to my Core Duo 2 Debian
machine for cross-compiling. I was unable to get past the .config step.
Debian's patches must hinder cross-compiling in some manner. For example,
make menuconfig seems to refuse to display MIPS as the architecture
I've been mainly using a working Debian 2.6.18 config (i.e. the one from
their package which lets me compile working 2.6.18 from the Debian
sources), but the default config (set to IP32, RK5, etc.) panics at boot
as well. Not sure if the message is 100% identical, I can double check if
anyone thinks that would help.
Thanks again for all the help, it's appreciated.
One, make sure you're doing "make vmlinux.32", and two, CONFIG_BUILD_ELF64 is
_not_ enabled. For 2.6.20, I had to cram in a patch from Frank to get these
things to not PROM crash (due to the elimination of CPHYSADDY and replacement by
__pa()), but on 2.6.21, this patch was unnecessary. Unsure about 2.6.22-rcX.
O2's will boot a pure 64bit kernel, but my experience is that they are
ridiculously slow at it (the console lags severely). vmlinux.32 is the modern
method of 64bit-code-in-a-32bit-shell, which the O2's and IP22 systems will
swallow much better.
Also, gbefb must be no greater than 4MB memory in menuconfig.
And what's the MHz of your R5000? 300MHz?, if so, it'll be the RM5200, and
you'll want "RM52xx" for CPU instead.
