If you use gxx, this is taken care of for you.

Try reading section 8, specifically 8.7.  If none of that helps, try
reposting your problem, and mention that you didn't find the answer
in the FAQ.

Another thing that comes to mind is the possibility that 'new' is an
inlined function in C++.  There are a couple of functions that are
defined only in the header files as inline functions.  If you don't
compile with optimizations, however, then they aren't inlined and
the linker tries to look in the libraries for the functions and doesn't
find them.  Try using -O when you compile, and see if this resolves
the problem.

BTW, don't worry about optimizations vs. debugging info; gcc allows
you to do both at the same time.
