Hi, I tried 3.05/02 and the behavior is the same. I've made an even simpler example which requires no external shared libs. It is on the same website: http://dustbunny.physics.indiana.edu/~dkrop/root_problems Note that the location of the ntuple files must be correctly declared in the header file before testing. I would be interested if anybody can reproduce the behavior I have seen. Thanks again, Dan On Tue, 2003-03-04 at 04:15, Rene Brun wrote: > Hi Dan, > > I cannot test your system because your external shared lib cannot run on > my systems.
