Hi,

Is it possible to use STL in a template class? When I tried to compile
a template with a vector<Int_t> as a memeber, I get a long list of
errors, starting with:

--------------------------------------------------------------------

        G__letint(result7,105,(long)((vector<int,allocator<int> >*)(G__getstructoffset()))->reverse_iterator(*(vector<int,allocator<int> >::reverse_iterator*)libp->para[0].ref));

These are my sources:

====================================================================
= TestClass.h
====================================================================
#ifndef __TestClass__
#define __TestClass__

#include "TObject.h"
#include <vector>

template<class Type>
class TestClass : public TObject
{
public:

  TestClass();
  ~TestClass();

private:

  Type *_tree;

  vector<Int_t> vi;

  ClassDefT(TestClass, 1)
};

template<class Type>
TestClass<Type>::TestClass()
{
  _tree = new Type;
}

template<class Type>
TestClass<Type>::~TestClass()
{
}

#endif 

====================================================================
= TestClass.C
====================================================================
#include "TestClass.h" 

====================================================================
= TestClass.C
====================================================================
#ifdef __CINT__

#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;

#pragma link C++ class TestClass<Double_t>+;

#endif
