Providing exact errors here would be more helpful in reasoning about the 
problem.
Anyway, Most common cause of this problem could be that you are not 
linking your program with boost thread library ( i.e. libboost_thread-mt.a).
It could result in errors saying "Undefined Symbols".

If you have indeed linked boost thread library with your program then 
another reason for errors could be that you have used different link 
flags. I mean that you may have missed "/MT" flag while compiling your 
program.
