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__

Thanks for all possible idea.
