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).
Source and binary RPMs are available here:
ftp://ftp.ges.redhat.com/private/releng/arm-linux-beta
These were built on a 32 bit RHEL3 host. It works just as well on a x86_64 Fedora 7 box, so no worries if you want to rebuild. Unless otherwise directed, tools will install under /opt/redhat/gnupro-07r1-1/H-%{_host}/bin
To rebuild you need to define %target like so:
rpmbuild -ba --define 'target arm-linux-gnueabi' gnupro.spec
All feedback appreciated.
