RE: [ROOT] STL map pair problem.

Hi,

To use the I/O of any templated class (beside the STL containers) with
ACLiC,
you have to add to your header file

#ifdef __MAKECINT__
#pragma link C++ class pair<int,int>+;
#endif

or the equivalent for your class.

Cheers,
Philippe.

Hi,

It looks like ACLIC is not able to generate the definition for the
dictionary of
the class pair<int,int>. Instead of ACLIC, do, eg:

rootcint -f mapcint.cxx -c RtgObject.hh maplinkdef.h
g++ -g -fPIC -I$ROOTSYS/include -c mapcint.cxx RtgObject.cc
g++ -g -o A RtgObject.o mapcint.o `root-config --libs` -lPhysics

with maplinkdef.h:
#ifdef __CINT__

#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;

#pragma link C++ class RtgEvent+;
#pragma link C++ class RtgMet+;
#pragma link C++ class RtgTrack+;
#pragma link C++ class RtgTower+;
#pragma link C++ class RtgPhoton+;
#pragma link C++ class RtgElectron+;
#pragma link C++ class RtgMuon+;
#pragma link C++ class RtgTau+;
#pragma link C++ class RtgPi0+;
#pragma link C++ class RtgCesMatch+;
#pragma link C++ class RtgJet+;
#pragma link C++ class RtgBoson+;
#pragma link C++ class pair<int,int>;

#endif
