Hi Rutger,
The I solved it for various packages of software for ALICE
is to have a linkdef.h for each package separately containg :
#ifdef __CINT__
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ class A;
#pragma link C++ class B;
#pragma link C++ class C;
#endif
where the classes A,B and C are the classes contained a
that particular package.
Note : The dictionary files produced by ROOTCINT for your various
packages should all have different names.
In this way you can load in a certain ROOT session/ batch job
more than one of your packages without problem.
