Yesterday I downloaded and built the latest Quantlib ( 1.0.1 ) using the latest Boost ( 1.44.0 ) using Visual Studio 2008. The code built cleanly and all the tests pass.
I also tried Visual Studio 2010 but ran into a series of minor problems which I worked around and then some more major compile problems at which point I gave up on VS 2010.
If you are going to use msvc to compile quantlib, you probably should stick with VS 2008. Fortunately VS 2008 is still available as a free download from Microsoft.
