Hi,
I have the following macro which I run off the command line of 2.00/05
on Linux. If the last four lines are commented out it works as I would
expect. When the last four lines are added, the interprter complains about
not being able to handle the copy constructor...
Error: Can't call TH1F::TH1F() in current scope
FILE:/usr/home/chris/analysis/qdc/clicks/./chargespec.C LINE:68
*** Interpreter error recovered ***
Thanks,
Chris
