So we did get the ability to compile C++ programs for NewtonOS just a short six years ago, and now it seems that we’ll have to plan for it going away: GCC 8.5 was the last version to support ARMv4, and as such is already quite old. The challenge will be to find versions which run on Apple Silicon come 2027, when Rosetta will not be supported by Apple anymore…
Makes me wonder whether trying to either get CFront 2.1 working again, or use mosrun instead of fiddling with GCC cross compilation
