how-to build 64 bit enabled gcc compiler

[Rita Chiu]

Hi everyone,

I am wondering if it is possible to build a 64 bit enabled gcc compiler
using a 32 bit gcc compiler and a 32 bit PPC kernel?  If so, what kind
of options and tools are required for this process and how?  Thank you
everyone in advance.

Currently, the 32-bit compiler I have has the following config:
Reading specs from ./../lib/gcc-lib/powerpc-unknown-linux-gnu/3.1/specs
Configured with: ../src/gcc-3.1/configure --prefix=/usr/local/3.1.0
--enable-threads=posix --enable-languages=c,c++ --disable-shared
Thread model: posix
gcc version 3.1

And the kernel and system type is (from "uname -rmsp"):
Linux 2.4.2 ppc unknown


Best Regards,
