Back in the day, crosstool was a solid way to build cross-compilers: http://kegel.com/crosstool/ http://kegel.com/crosstool/ I haven't really kept up with the latest stuff, but I've seen mentions of crosstool-ng, which may be a newer take on it: https://github.com/diorcety/crosstool-ng https://github.com/diorcety/crosstool-ng So, no, it's not next-to-impossible. It's a little complicated, and that's why these projects exist, but my memory of crosstool was that it made it trivially easy: run the script, let it compile for a bit, and voila, you now have a brand-new cross-compiler toolchain.
