[Linaro-dev] linaro build system (was Re: Availability of hardware for Linaro development?)

[David Rusling]

There's a blueprint here - https://blueprints.edge.launchpad.net/ubuntu/+spec/arm-m-xdeb-cross-compilation-environment - for the cross compilation / build work.   There are two distinct strands, getting better cross build tools (I'm personally not keen on scratch box, too hacky to set up and slow) and getting decent build hardware available.   The hardware will come.
