Would there be the possibility to extend rootcint? I have a few comments to this. First, #pragma link command does not instatiate the template class, it only tries to refer already instantiated template classes. In order to link instantiated template class, you need to instantiate it in normal C++ code. For example, typedef STLObjArray<MC_Track*> DummyType1; #pragma link C++ class STLObjArray<MC_Track*>-; But, I understand it is nice to instantiate template class on #pragma link. I'll think about doing this in future version. Second, #pragma link command with '*' in it's name field behaves somewhat differently. Rootcint or cint takes it as a wildcard character. So, it is actually interpreted as 'STLObjArray<MC_Track[A-Za-z0-9_]*'. This is usually fine, except that '-' flag at the end is ignored. For now, workaround is to use typedef. typedef MC_Track* pMC_Track; typedef STLObjARray<pMC_Track> DummyType1; #pragma link C++ class STLObjArray<pMC_Track>-; I want to improve this in future version.
