Dear list,

I'm starting with boost (Boost.Asio) and I'm following the tutorial available at Boost.Asio web-page.

I'm stuck at part 5 (Timer.5) because I'm getting the following linker error:

timer_5.cpp:(.text+0xb3): undefined reference to `boost::thread::~thread()'

timer_5.cpp:(.text+0xe1): undefined reference to `boost::thread::~thread()'

collect2: error: ld returned 1 exit status

I'm linking boost_system, boost_thread and pthread (I compiled the boost libraries and at some point I thought that I was including .hpp files from a different version of the libraries but I specified the paths of both .hpp and libraries and the problem remains).

The system runs GNU/Linux 64bits (Fedora 17) with GCC 4.7.2 and boost 1.51.0.

Any idea?
