Thanks Lars, you solve my problem.
Effectively, I was linking with the static lib.

When I was looking how to build shared libs, I found in the boost
documentation that shared build should be the default.
http://www.boost.org/boost-build2/doc/html/bbv2/tutorial/linkage.html
I'm under Windows, and without add link=shared to the b2 command line, the
build is static.

Next was the problem to link my app with boost. It was necessary to
define BOOST_ALL_DYN_LINK in boost\config\user.hpp, while the comment just
above says that it should not be needed for boost_thread : "Forces all
libraries [...] to be linked as dll's rather than static libraries on
Microsoft Windows. [...] Note that there may be some libraries that can
only [...] be dynamically linked (Boost.Threads for example), in these
cases this macro has no effect."

Is something I didn't well understand ?

Anyway, it now works,

Thank you again Lars,
