TClonesArray of self defined classes

Hi,
Using root 1.03/09 on a SGI macine running IRIX 6.2, I've got a
problem in declaring a TClonesArray of a self defined class:

Neglecting ClassDef and ClassImp on their correct positions, these
classes are invalid for root applications and it's impossible to
create a TClonesArray of them (why?).

Defining ClassDef and ClassImp in the class definition and
implementation,
and using rootcint to create the dictionary, I receive an error
message like:
/products/cernroot/pro/sgi_62/gcc/root/bin/rootcint -f Dictionary.C -c -I/products/cernroot/pro/sgi_62/gcc/root/include -I. -I./include/arte -I./include/auto -DUSE_ROOT -p -t \
RecoTower.hh RecoCluster.hh RecoEvent.hh LinkDef.h
Note: operator new() masked 1c
Warning: Link requested for undefined class RecoEvent FILE: LINE:0
Warning: Link requested for undefined class RecoTower FILE: LINE:0
Warning: Link requested for undefined class RecoCluster FILE: LINE:0

Afterwards the program Compilation ends up with unresolved symbols
like :
RecoEvent::Class_Version
RecoEvent::DeclFileName
and so on

What can I do to overcome this problem?

Thanks, Robert
