you've hit a "feature". rootcint does not include the include
file for TH1F (TH1.h) in the generated code, which causes the
compile error. To work around this, change:
class TH1F;
to
#include "TH1.h"
I'll try to fix this problem in rootcint (but it will be
difficult for classes that do not have their own header like
TH1F).
Cheers, Fons.
