It seems like you are using gcc instead of gxx, and therefore standard c++ linraries are
not linked - and the 'new' operator is not found.
your code compiled fine with gxx .
also , make sure you have a proper file extension - cxx/cpp/cc

: when this function is placed before 'main' in my source, cut and pastewize,
