Does any one have recent experience with compiling / installing Boost on a Mac using gcc? A brief vox-poll seems to say that most everyone on the Mac uses it with CodeWarrior, manually including it in their project. However I'm more interested in using gcc / ProjectBuilder, and distributing the source code to my programs. So, I need to know if my end-users are going to have any problems installing Boost? My attempts have been been discouraging. The first install of Spirit almost immediately consumed all the memory on my machine and thrashed. Installation of the full Boost failed with link errors reporting "unrecognised option shared". Editing this option out of the regex makefile, lead to the next problem, failures with the unittests. Suspecting I was missing something obvious, I handed the problem over to someone else who spend a few days following the same trail, eventually commenting out the unittests. Sure, I could include the boost source with every program I use it in, but this strikes me as untidy and means every time Boost updates, I have to update the x separate copies on my disk.
