I'm having a similar problem with my project. I'd like to use the dlls but no matter what, the compile warns me that it "cannot open file 'boost_regex-vc80-mt-gd-1_38.lib'" I'm trying to find where I can set the project (in vis studio 2005) to use the dynamic link libraries as opposed to the static. Based on previous entries in this thread, I assume that is the first step that I need to take. Can someone tell me where to set this?

You can not link the static runtime and dynamic boost_thread or any other lib.

Why did I linked successfully with static thread library when my project is set to multi threaded debug dll? You can link using the dll runtime and the static boost_thread. In Christ, Steven Watanabe
