Here is some more on this problem. Perhaps someone on this list has some ideas where to look? Defining BOOST_NO_THREAD (or whatever it was) will "fix" the problem, but I suspect it's not the correct fix. The code will link OK dynamically, but not statically. That's strange.

Can you find out what exactly uses them without making them weak? On Friday 28 March 2003 08:09 am, Neal D.
