Hi I am using boost(1.34.1) signals on linux(centos5) with gcc 4.1.2. I can link to the static boost_signals-gcc41-mt library, however the following symbols seem to be missing. They all seem to be related to boost::signals::named_slot_map_iterator. Other symbols such as boost::signals::connection::~connection() are found. ../../../bin/x86_64/32/linux/g++4.1.2/release/libIceExchangeCommon.so: undefined reference to `boost::signals::detail::named_slot_map_iterator::named_slot_map_iterato r(boost::signals::detail::named_slot_map_iterator const&)' ../../../bin/x86_64/32/linux/g++4.1.2/release/libIceExchangeCommon.so: undefined reference to `boost::signals::detail::named_slot_map_iterator::operator=(boost::signa ls::detail::named_slot_map_iterator const&)' ../../../bin/x86_64/32/linux/g++4.1.2/release/libIceExchangeCommon.so: undefined reference to `boost::signals::detail::named_slot_map_iterator::dereference() const' ../../../bin/x86_64/32/linux/g++4.1.2/release/libIceExchangeCommon.so: undefined reference to `boost::signals::detail::named_slot_map_iterator::increment()' ../../../bin/x86_64/32/linux/g++4.1.2/release/libIceExchangeCommon.so: undefined reference to `boost::signals::detail::named_slot_map_iterator::equal(boost::signals:: detail::named_slot_map_iterator const&) const' collect2: ld returned 1 exit status Has anyone seen this before? Thanks in advance.
