Hi Tobias,
This looks like a side-effect of one of the many Microsoft include files with many “define” statements. In particular GetObject is one of these keywords used by MS.
Look at $ROOTSYS/base/inc/Windows4Root.h
you will see a long list of such keywords that we have to undefined. GetObject is alao
referenced at the end of the file.
In your case, I would suggest to
-either #include “Windows4Root.h” in your class at the end of all includes
-or add the sattement
#undef GetObject
