Hi. I'm trying to build libtorrent ( http://libtorrent.sf.net ) on xp+mingw+msys and I get some errors regarding boost. Hopefully someone can help.. Sorry if its not much of a boost problem.... I've attached compiler output text as as .txt file... ~/E/libtorrent-0.11 $ make make all-recursive make[1]: Entering directory `/home/devel/E/libtorrent-0.11' Making all in include make[2]: Entering
