main.mk introduced, lib/*.mk partially rewritten The former toplevel Makefile is now toplevel main.mk; this change allows for multi-target, multi-arch processing in the current toplevel Makefile. As the "build" symlink semantics change quite considerably when one is doing bulk builds (several pruned builddirs might be useful for comparison), BUILDDIR is now much more likely to be recreated: the cases when it will persist are when it's either a single-image build or when the prefix hasn't changed. There are some more or less subtle bugfixes and enhancements all over the map as well. Done within 20111230..20120102 timeframe, actually... 2011-12-30 14:46:58 +04:00			`# umbrella mkimage-profiles makefile:`

Makefile: presume a distro by default When ve/ support was introduced, a simple "make icewm.iso" had to turn into the more elaborate "make distro/icewm.iso". This latter one involves several keystrokes more, which is not even (environ)mentally friendly. This was supposed to get fixed somewhere down the road with a fallback but the elegance of IMAGE_* setup waterfall barred me from tweaking IMAGE_TARGET at once (and the downstream fixup would imply re-tweaking the consequent variables as well which is blatantly anti-mkimage-profilic being a brute fork). OTOH testing for a "directory" part of the goal is going to either deadlock on IMAGE_CLASS or duplicate its assignment. So now when I've had enough typing an extra "distro/", I'm going to just bite the bullet and tweak IMAGE_TARGET with a test duplicating IMAGE_CLASS assignment indeed (testing for e.g. "/" results in a different test, which would be worse yet). Please suggest a more elegant solution if you invent one! 2011-11-21 15:42:59 +04:00			`endif`
official {distro,ve}/* support This is quite a large-scale change since mkimage-profiles got used to baking distributions over the last year, and virtual environments are quite different, so e.g. image.in/Makefile had to be split in two with the main part of it moved into features.in/iso/lib/. Short overview: - features.in/Makefile: lib/ support (supporting VE images requires dynamic modifications to image.in/Makefile before starting the build; the most natural way to achieve that seems to use features mechanism along with makefile include dir) - packaging format related part moved into features.in/pack (should be better prepared for diversity either) - features.in/iso renamed to features.in/build-distro - features.in/ve renamed to features.in/build-ve + NB: these could not be merged as e.g. features.in/build due to completely different script hooks - lib/image.mk renamed to lib/build.mk - image, config, log postprocessing moved downstream - added a sort of a topping in the form of lib/sugar.mk - assorted style fixups (like ifeq usage) - clean.mk: reliability fix (the problem was observed by Oleg Ivanov and me too but finally it did get the attention quantum) - reviewed, updated and extended docs + QUICKSTART: should be[come] a step-by-step guide (thanks Leo-sp50 for prodiving feedback) 2011-10-06 12:46:31 +04:00			`endif`
