You haven't given nearly enough information.  Provide the exact commands
that you use to compile and link.  Better would be a small testcase that
demonstrates the error.  It is also useful to provide the cygcheck
output as requested at <http://cygwin.com/problems.html>.

As a wild guess, I'd say you're trying to link by invoking gcc instead
of g++.  You need to link with g++ when compiling C++ code as it will
add all the necessary options, flags, and libraries to support C++ code.
