[M3devel] AMD64_DARWIN with OSX Mavericks

[Jay]

I do repeatedly wonder if we should be a thin layer over automake/autoconf/pkg-config/libtool. I look into them every so often. What bugs me, maybe not pkg-config, is that they seem slow and have to generate files. I want something that usually makes fast decisions for every run. Optionally recording them in a file for bootstrapping or overridability. Cm3 was ahead of its time, kinda, but those tools solve much of the same problem, with other people maintaining them and more "dynamism"/"manifestation" -- I can't think of the word, but throw together a random posixish platform and autoconf can probe it and piece it together. There is no need to record static platform definitions and local configuration details are inferred/deduced at build-time, and there is good cross build support.


I've considered coding up similar in M3/Python/C/C++. 


I do put some runtime tests in the config files. I suppose pkg-config is what we miss most, and we could read its files in cm3??? I.e. this is the part of the config files that are the most site-specific, and worse, need to change as surrounding packages are installed/uninstalled?


What autoconf is "really" for, we get very far with light dependencies ("the functions are assumed all present"), light ifdefing (m3core's preemptive suspend), and light "practicality" (I.e. picking out integer types).


Automake we basically have our own.


Libtool I believe works through static knowledge, like us.


And pkg-config, we miss out on largely.
