Hi. I downloaded Boost 1.33.1 and tried to compile it under Visual C++ 2005 Express Edition, using 'bjam -sTOOLS=vc-8_0 stage'. It seems that everything compiled, but with *lots* of warnings. Most of the warnings can be devided into 4 categories: 1. option 'Og' has been deprecated and will be removed in a future release 2. You have used a std:: construct that is not safe. See documentation on how to use the Safe Standard C++ Library 3. The POSIX name for this item is deprecated. Instead, use the ISO C++ conformant name: ... 4. This function or variable may be unsafe. Consider using ... instead. I'm quite sure that they don't indicate any bug (am I right?), but I still don't think they should show up like this and intimidate users... Yuval
