net-libs/libtorrent misses some includes that are required by gcc-4.3. I have filed a bug report upstream. http://libtorrent.rakshasa.no/ticket/1266
Created attachment 145650 [details, diff] patch for missing includes
Created attachment 145651 [details, diff] One more missing include fixed The previous patch compiles libtorrent fine but fails when building rtorrent because one additional include was missing.
I've fixed it with a patch coming from Debian, which is basically identical. Thanks for reporting.
#include <string> is still missing in tracker_list.h. See my second attachment. This bug only triggers if you try to compile rtorrent against libtorrent.
Sorry missed that, fixed now.
