For using _beginthread you have to use the multi-threaded runtime lib. In VC6 you can choose the runtime lib in Project Settings->Compiler Settings->Code Generation. Use multi threaded DLL in all your sub projects. And do not mix multiple versions of the runtinme lib. hope this helps Alex

I am getting the following error while i compile boost thread library under VC++ 6.0. Could any of you please help me out.

Well pretty obviously you have to turn on multithreading support in your compiler before building the library: check out the code generation options in the IDE. John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm
