Brendan,
Thanks for posting this. I took a quick look. Please see comments below.

A few weeks back there was a big discussion on fedora-devel-list
about
cross compilers in relation to the Fedora arm project. Somewhere in the
thread I promised we (GES @ Red Hat) would put out our cross compilation
bits as proof of concept. While we're still making some changes to our
cross rpm packages, we can share our current cross compiler beta for
those who are interested. We're producing working root filesystems with
this compiler, so you should be able to as well.
A couple things to note: The tools are portion of the GNUPro toolkit
currently in development (aka gnupro-07r1-1) and is not based on the
sources from Fedora (It is gcc 4.2.1, for instance). We don't normally
build with RPM, so the spec file is a wrapper to our rebuild program
(Which handles the chicken/egg problem aka gcc/glibc).
Okay, this is essentially how cross-tool or codesourcery would build
their cross-toolchain? The scripts are different, but the idea is same.
Or, am I missing something?
Our goal with this project is to actually leverage fedora. In other
words, here are things I would like to be able to achieve...
1. The cross-compiler is "equivalent" to the native compiler. Thus,
if I mix cross-built packages with native built packages, it should
all just work.
2. When doing cross-building of packages and root file systems, we
should be using the Fedora packages. This is not a problem that the
cross-compiler needs to address (except for glibc), but we need to
deal with it in the next step (i.e., building packages).
Could you explain how you leverage Fedora in your approach, or is that
not something you particularly care about?
Thanks
