Gabor:
I just got binutils 2.12, gcc 3.2.3, and glibc 2.2.5 working on my Red Hat
Linux boxen, and I'm targeting mipsel-linux. If you would like the source /
binary RPMs to see what I did, let me know; maybe Alien can fix them up
for you.
I feel your pain concerning the cross compiling. I at first tried to install
GCC 3.2 everything to /opt/toolchains using --prefix and/or other options, but
it seemed like GCC was particularly upset with --prefix. I tried the gcc 3.2.3
source WITHOUT --prefix, and it seemed to configure itself properly and coexist
OK.
Best of luck!
