Pointers in STL

Question

Is it possible to use pointers in STL?
I tried to use pointers in STL queue.
It is giving compilation errors while linking.
Is it necessary to allocate and deallocate memory by us while doing a push and pop in queue?
Please suggest a way to solve the linking error problem
The error is as follows
Undefined first referenced
symbol in file
void std::deque<MsgBuf,std::allocator<MsgBuf> >::__allocate_at_end() ../sunlib/libMqApi.a(MQ_GuardedQueue.o)
void std::deque<MsgBuf,std::allocator<MsgBuf> >::__deallocate_at_begin() ../sunlib/libMqApi.a(MQ_GuardedQueue.

The official term is reference, but you can use reference and pointer interchangeably in mosts contexts.
What Java has is references--that is, [url http://java.sun.com/docs/books/jls/third_edition/html/j3TOC.html]the JLS defines that term for the types that are used to access objects and describes references as being "pointers to objects". They are pointers in a general sense--they point at something.
Java pointers are very much like C/C++ pointers in some ways, but they are much more tightly restricted in what you can do with them. You can't cast them willy-nilly to any old type, or give them arbitrary values, or do arithmetic on them, or see the values they hold. They are opaque.
