Bruno,

The symbols it's looking for are should be in your implementation's
C++ runtime library.  Typically the kind of error you cite is caused
by using gcc instead of g++ to do the linking step, though I'm a bit
surprised not to see similar errors reported about iostream support.
The only other thought I have is that maybe codeblocks is actually
using a different compiler than the one you used to build
Boost.Threads.
