Hello. I'm quite new, and I've been needing Boost for something else I'm trying to compile... I've been trying to compile Boost, but it's giving me errors. Unfortunately, I can't use Debian's apt-get to get Boost, because I need version 1.5 or greater, and apt-get (for this version of Debian) only gets 1.49.0. I've put some feedback it gave me below. I've already run ./b2 (no arguments) before, so that's where the found targets are coming from. I'm not sure why I'm getting these errors...A whole bunch of header files are reported missing. I tried re-downloading Boost, and using a different format (tar.bz2 instead of tar.bz), but it still does the same thing. Building the Boost C++ Libraries.
