Hello,
I am trying to build a gcc/g++ tool-chain for i486 architechture on an
x86_64 machine.
I downloaded gcc-4.1.2 and configured it with host as x86_64 and target
as i486 after installing the pre-requistes i.e gmp, mrpf, and mpc
libraries .
../gcc-4.1.2/configure --with-gmp=/auto/local//prbatra/gcc-install/
--with-mpfr=/auto/local//prbatra/gcc-install/
--prefix=/auto/local//prbatra/gcc-install/ --host=x86_64-gnu-linux
--target=i486-gnu-linux --enable-languages=c,c++,objc
I also installed binutils with the same host and target for asssembler,
loaded etc

Can someone help me with what I am missing?
Gcc 4.1 wasn't a particularly stable version, even if you could spell
the pre-requisites correctly, making your exercise appear somewhat
pointless. You would require a complete 32-bit development system,
including 32-bit libpthread, which apparently you neglected.
