The REBOL 3 code is now open source.
http://www.rebol.com/article/0519.htmlHere is a snippet from the main generated makefile you might find interesting:
Quote:
# REBOL Makefile -- Generated by make-make.r (do not edit) on 14-Dec-2012/11:33:43+2:00
# This makefile is intentional kept simple to make builds possible on
# a wider range of target platforms.
# To cross compile or build for other target:
# $TOOLS - should point to bin where gcc is found
# $INCL - should point to the dir for includes
# Example make:
# make TOOLS=~/amiga/amiga/bin/ppc-amigaos- INCL=/SDK/newlib/include
Carl Sassenrath did the AmigaOS port of REBOL 3 himself. I believe ACube supplied him the system and I provided some minimal tech. support.
I haven't yet tried building it on AmigaOS but it should "just work" out the box if anybody wants to give it a try. That will give you the basic REBOL core without a host kit.
I hope to get back into REBOL 3 and release the Amiga
host kit early in the new year. I already have a basic GUI working which was
documented on my blog way back when.
