Dear Andrei,

I'm using ROOT 3.10.01 on RH9 gcc3.2.2-5

I am trying to compile a program that includes TGeoTrack.h and I get the
following compiler error

In file included from /home2/root/3.10.01/root/include/TGeoTrack.h:16,
                 from ReadEvent.cxx:8:
/home2/root/3.10.01/root/include/TVirtualGeoTrack.h: In member function
   `TVirtualGeoTrack* TVirtualGeoTrack::GetDaughter(int) const':
/home2/root/3.10.01/root/include/TVirtualGeoTrack.h:61: invalid use of
   undefined type `struct TObjArray'
/home2/root/3.10.01/root/include/TObject.h:50: forward declaration of
`struct
   TObjArray'
/home2/root/3.10.01/root/include/TVirtualGeoTrack.h: In member function
`Int_t
   TVirtualGeoTrack::GetNdaughters() const':
/home2/root/3.10.01/root/include/TVirtualGeoTrack.h:65: invalid use of
   undefined type `struct TObjArray'
/home2/root/3.10.01/root/include/TObject.h:50: forward declaration of
`struct
   TObjArray'

Is this an ROOT problem or am I doing something wrong?  I am able to run
this program in CINT without any problems.  

Thanks
Kerry
