  46 # ordinary compilation, we just do these phases consecutively on the
  47 # same machine, but if you wanted to cross-compile from one machine
  48 # which supports Common Lisp to another which does not (yet:-) support
  49 # Common Lisp, you could do something like this:
  50 #   Create copies of the source tree on both the host and the target.
  51 #   Read the make-config.sh script carefully and emulate it by hand
  52 #     on both machines (e.g. creating "target"-named symlinks to
  53 #     identify the target architecture).
  54 #   On the host system:
  55 #     SBCL_XC_HOST=<whatever> sh make-host-1.sh
  56 #   Copy src/runtime/genesis/*.h from the host system to the target
  57 #     system.
  58 #   On the target system:
  59 #     sh make-target-1.sh
  60 #   Copy src/runtime/sbcl.nm and output/stuff-groveled-from-headers.lisp
  61 #     from the target system to the host system.
  62 #   On the host system:
  63 #     SBCL_XC_HOST=<whatever> sh make-host-2.sh
  64 #   Copy output/cold-sbcl.core from the host system to the target system.
  65 #   On the target system:
  66 #     sh make-target-2.sh
  67 #     sh make-target-contrib.sh
  68 # Or, if you can set up the files somewhere shared (with NFS, AFS, or
  69 # whatever) between the host machine and the target machine, the basic
  70 # procedure above should still work, but you can skip the "copy" steps.
