Hi Shuwei,
take a look at the generated dictionary. I suspect you'll find it
generated correctly. According to Fons the error diagnostics you're getting
has to do with the memory cleanup and it is printed by rootcint *after* the
dictionary has already been generated (see below).
-regards, pasha.

Hi Pasha,

this bug has just been fixed (was related to cleanup code in rootcint
after dictionary was correctly generated). To get rid of the problem
add the following line to the bottom of rootcint.cxx:

G__globalcomp = -1; // G__CPPLINK <--- add this line
G__exit(0);

return 0;
}

Cheers, Fons.
