Any plans adding cross-compilation support to your > build-system, barriers to overcome? For Emacs, there are layers of problems. First things first, we are only doing byte compilation atm, which may or may not be arch-dependant based on stuff like endianness. For native compilation, there is the thing that even a slightly differently configured emacs won't load the packages you've just compiled without compiling it natively on its own. Granted, if we want to do cross-compilation, having just the bytecode might already be "good enough", but I wanted to throw this out there. I think we'd need some support from Emacs proper before we can start implementing cross builds. Cheers
