This was discusedin length right after 1.34. was out. The problem
essencially is that -lboost_unit_test_framework-gcc41 in your build command
picks up incorrect version of the library. You should've used static
version, while it picks up shared one (they both similarly, only extension
is different). You've got several ways to deal with it:
1. rename shared library version of Boost.Test
2. enforce static library selection with -Bstatic and/or -Dn compiler's
flags
3. Use aut registration instead combined with
BOOST_TEST_MAIN/BOOST_TEST_MODULE
#include <iostream>
#define BOOST_TEST_MODULE my test
#include <boost/test/unit_test.hpp>
BOOST_AUTO_TEST_CASE( my_test_function )
{
std::cout << "hi there" << std::endl;
}
