[boost] Static Member declaration GCC

Hello,
I tried to declare a boost:shared_ptr as a static member of a template
function. If I compile the program with Visual Studio all are Ok. If I try
to compile the code with gcc, gcc failed with:

t1.cpp:71: error: too few template-parameter-lists
t1.cpp:72: error: too few template-parameter-lists

There is a small mistake in my code but I can't find the error.

Can someone help me?
Bye
  Bernd

  t.instance()->Set(45);
  int b=t.instance()->Get();
  return b;
