I doubt that you're using a real R3000.  What processor are you using?

If it's TX39/R3912 you should look at the linux-vr CVS archive
 www.linux-vr.org ).  Linux boots and runs on several devices based on the
R3912.

gcc 2.95.1 appears to work (rebuilds glibc and some apps) after the
application of
ftp://ftp.place.org/pub/nop/linuxce/gcc-2.95.1-interim-990916.patch.gz , but
Klaus is right, egcs-1.0.3a+mips and binutils 2.8.1+mips are the gold
standard for development right now.

(I really need to update my toolchain makefile+patches to work with more
recent kernels...)
