Subject says it all - What is the status of uclibc + powerpc ?
I tried using my homegrown powerpc cross compiler ( hosted on x86 ) and although
busybox and uclibc appeared to compile correctly all I got was a kernel panic
with no init found.
I downloaded Eriks 3.0.3 toolchain ( modified TARGET_PATH and TARGET_CPU ) but
it failed during stage 5 with the following.

Removing the c++ language support gave me a working toolchain. However the the
final gcc and gccbug mv's failed as they weren't present in {TARGET_PATH}/bin.
Is ths important ?
Trying to compile busbox directly with the new toolchain gave the following error -

I tried compiling busybox dynamically linked to uclibc using the uclibc wrapper
and got a kernel panic. Statically linking allowed me to enter the shell (ash)
but all commands had to run with the full pathname and "/bin/ls /" only gave a
"/" as output. O
I've tried building with malloc and malloc-simple as hinted in the uClibc Config
but with no success.
The target platform works with the same kernel but with busybox dynamically
linked to glibc.
Any hints/tips would be gratefully received ?
PS. Is there a searchable version of the uClibc mailing list archive out there ?
