Hello.

I have a program that makes use of the vector class from the STL.  I
have a vector of String objects.  When I attempt to build my program 
using the following command :
  gcc mail.cpp -o mail -lstdcx
I get the following error message :
 
mail.cc (.text+0x4a56): undefined reference to
'vector<Message>::operator=(vector<Message> const &)

I looked in the vector header file and saw that the '=' operator was
overloaded for vector class - using the following prototype:
    vector<T>& operator=(const vector<T>& x);

My questions :
1) Is my program looking for a different signature for = operator (or am
I misinterpreting the error message)

2) Assuming the  the = operator of vector class is defined correctly,
has anyone encountered this a problem and if so what was your workaround
for it.

3) If there is no workaround how can I find out where the reference is
occuring?

4) Am I barking up the wrong tree?  Its happended before :-)


Thanks for any help/insight you can provide.
