I'm playing with a dependency checker I wrote that tells me what Boost module depends on what. Starting with the basics:
Dependencies for config:
detail: boost/detail/endian.hpp
A dependency from config to detail is not a good thing because detail depends on too much.
The 'boost/detail' really isn't a library as it is just a number of individual header files none of which belong to any particular library. So thinking about what 'boost/detail' as a whole depends on does not seem worthwhile.
boost/detail/endian.hpp is now only a forwarding header to predef, so it could and probably should be moved to predef, which seems to depend on nothing.
OK.
But I was wondering what in config uses endian.hpp. Turns out the only use is in boost/detail/limits.hpp, a file that has been put into config for some reason.
I don't see where endian.hpp is being included by limits.hpp.
I can't find anything in config or in Boost that uses this file. What is its purpose?
John or Dave should know. Hopefully one of them will answer that.
