RE: rootcint error

Hi Akira,

If you generate the dictionary for your class using rootcint, instead of doing "#include the same header in a macro", you should simply use the library you build. In addition, you "#include the same header in a macro", this means that you intent on 'interpreting' your library code ... which I have to believe is __not__ what you want. (aka doing "execute it with the '+'" is anyway the right thing to do if you don't have the dictionary already generated).

Cheers,
Philippe.

Hello Philippe,

-p option works when I use rootcint in command lines. However if I #include the same header in a macro and execute it without "+",
ROOT dumps similar errors.

Do you have any solution ?
