Hi,

Is there any archive place for roottalk ?
I've lost the last answer for a message about templates
with rootcint and I get the following error:

cxx -w -g -I/virgoApp/Fr/v2.30/src -I/virgoa1_3/xavier/root/include
-I../src -c ../src/MyCanvasDict.cxx -o ../obj/MyCanvasDict.o
cxx: Error: ../src/MyCanvasDict.cxx, line 471: In this statement, the
argument list "R__b>>ListText" matches no "operator >>".
R__b >> ListText;
------^
cxx: Error: ../src/MyCanvasDict.cxx, line 475: In this statement, the
argument list "R__b<<ListText" matches no "operator <<".
R__b << ListText;

MyCanvasDict.cxx is created by:
rootcint MyCanvasDict.cxx -c MyCanvas.h

Here follow the code of
MyCanvas.h
#ifndef __MyCanvas__
#define __MyCanvas__

//////////////////////////////////////////////////////////////////////////

class MyCanvas : public TCanvas{

public:
~MyCanvas();
MyCanvas();

ClassDef(MyCanvas,1) // MyCanvas structure
};

#endif

template<class Item>
class enhancedItem{

enhancedItem *next;

template<class Item>
class List{

public:

List(){first=NULL;last=NULL;current=NULL;}
Reset(){current=first;}

enhancedItem<Item> *Current(){return current;}
Add(Item &t);
Remove(enhancedItem<Item> *t);
Boolean is_at_end(){return current==NULL ? true : false;}
};

#endif

Thanks for all possible idea.
