Need some help with inheritence with STL

[pb]

Im getting this compile error,
undefined reference to BitString<10>::scramble()
collect2: ld returned 1 exit status

For some reason the compiler cant find the symbol for the member function i
declare. Everythign compiles correctly up to the point when i make a call to
the "scramble" routine. Calling the member functions of the base class work
just fine, but when i try to call the member functions i declare in the
extened class, the linker cant find the symbols. any ideas?

thx for the help...

// BitString.h

#include <bitset>
using namespace std;

template <size_t N>
class BitString : public bitset <N> {
public:
Bitstring <N>():bitset<N>(){};
void scramble();
};

//Bitstring.cpp

template <size_t N>
BitString<N>::scramble()
{
return;
}

// main.cpp
#include "BitString.h"
int
main()
{
BitString<10> data;
data.scramble()
return;
}

This issue is covered in Marshall Cline's C++ FAQ. See the topics
"[34.12] Why can't I separate the definition of my templates class
from it's declaration and put it inside a .cpp file?" and
"[34.13] How can I avoid linker errors with my template functions?".
It is always good to check the FAQ before posting. You can get the
