Re: no dictionary

Hi,

my suggestion here is that you substitute

>gSystem->Load("./checkOQ_cxx.so");

by

gROOT->ProcessLine(".L checkOQ.C+");

this will update the .so everytime you change the class. But it seems you are missing the header file where std::pair<std::string, std::string> is declared, you may try to do what Venkatesh suggested though.

Marcelo
