You are still not using your tools correctly. -L is for specifying a directory location.
The errors you are getting are because you are not linking the thread library.

Let me suggest that you take some time with a simple non-boost example and learn how the
compiler and linker work. The problems you are having are simply because you do not
understand your tools. I am sure there must be some good tutorials on basic compiling/linking
somewhere on the web.

Good luck
Michael
