Probably the easiest approach would be to use the svm1 back end, with the caveat that it'll be a bit slow. (If you're willing to use a very similar board like an odroid c4 with a 64-bit it'll be a lot faster!) On an x86 host where you've already installed MIT Scheme, you can do something like this: cd mit-scheme/src ./Setup.sh ./configure --enable-cross-compiling --enable-native-code=svm1-32le make -j4 cross-host Then rsync the directory over to the odroid and run: cd mit-scheme/src (cd microcode && ./configure) make -j4 cross-target env FAST=y make check You'll need a C compiler on the odroid xu4 to do the second stage. The cross-compilation system we have is not very good at the moment -- it can't cross-compile everything, and it can't take advantage of a C cross-compiler at the moment, which is why you have to rerun configure in the microcode directory and run `make cross-target' to finish the job.
