Hi Yuri,
can you try and add :
#include "lcio.h"
to /home/chill/Research/lcio/trunk/src/cpp/include/UTIL/LCIterator.h
If that works we can commit it to the LCIO svn...
Cheers, Frank.

To me, this seems like a simple namespace issue, because ‘lcio’ is a namespace that is referenced from that code. So perhaps this namespace has a ‘using’ statement that is for some reason not seen on Ubuntu. (I don’t know. Just a guess.)
