Hi All,

I am using boost_1_47_0 and (GCC) 4.6.3. The C++ application on linux
complains on the following in linking.

boost_1_47_0/boost/lockfree/detail/freelist.hpp:124: undefined reference to
`std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>
>::operator
boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>()
const'

/boost_1_47_0/boost/lockfree/detail/freelist.hpp:124: undefined reference to
`std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>
>::operator
boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>()
const'

collect2: ld returned 1 exit status

I looked into http://tim.klingt.org/code/projects/boost-lockfree/repository/revisions/423be9f76bf96230b55ac00d84450f5349c483fb/show/boost

and dowloaded lockfree changed files. But the issue still exists.

boost_1_47_0/boost/lockfree/detail/freelist.hpp:117: undefined
reference to `std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>
>::compare_exchange_weak(boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>&,
boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>,
std::memory_order)'

boost_1_47_0/boost/lockfree/detail/freelist.hpp:87: undefined

Any idea on this ?
