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:

`boost::signals::detail::named_slot_map_iterator::increment()'

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.
 
Michael
