How to build Cross Compiler Toolchain on Fedora for other Li

[drroot]

my Linux: Fedora 14 x64
my gcc: 4.5.1
my Glibc： 2.12.90

target Linux: "Ubuntu 8.04.4 LTS" hardy
target kernel: 2.6.24-29-server x64
target gcc: 4.2.4 target Glibc： 2.7

I need gcc/g++ and fortran.

I Googled and most documents I found are somehow outdated and targeting for ARM, not for other Linux.

Any step by step document will be greatly appreciated.

This is technically off topic, but we have a Wiki.

Perhaps you'll be able to grok the information you need from there.

GCC doesn't care which Linux it's on, as long as it's GNU based. Just build with *-gnu-linux as your host and target, where * is the architecture of the machine you're going to install Ubuntu on.

If you don't specify anything, it will select options optimal for you computer. If the Ubuntu is on the same machine as the Fedora, don't specify anything.
