Hi,

I've not used "-l" to link with the Boost thread library before.  Perhaps 
the name you use has to be more complete (include the gcc42-mt part) or the 
path isn't in your default library path.

You may try explicit static linking to the library by adding something like 
"/usr/lib/libboost_thread-gcc42-mt.a" to your gcc command line.  Check your 
system for the exact path/file name.
