Hi, I've done a svn check_out of the boost repository. I'm trying to build it with the underlaying options, but can't achieve that goal due to the underlaying error messages. Any help or hints will be appreciated Cheers Michael ps A couple of weeks ago, i was able to compile boost with the same options without a problem.
