I am assuming emails arrived in the wrong order and this is the second one.
I am not sure, does Apple ship 32bit frameworks on Sierra? Have you tried building 64bit!
No, not yet. I retried an ancient version of GNustep make that I have in use for many years. It had trouble installing in some directories, but I got it finally working on Sierra. I will retry the current GNUstep make again and try to get hot working as well. Any known issues with the recent GNustep make on MacOSX Sierra? Does anybody (except) me actually uses GNustep make on MacOSX?
