Dear Rooter and Valerie I am using ROOT 3.01.05 on windows 2000. I have a set of classes I would like to use in root I generate a dictionary for them like this: rootcint -f MyDictionary.cxx MyClass1.h ..... MyClassN.h linkdef.h During dictionary generation I get some warnings about Datamembers being pointers to fundamental types and thus cint does not know their size but since I don't need the streamers for the classes I don't really care I think. my linkdef.h looks like this: ==================================== #ifdef __CINT__ #pragma ling off all globals; #pragma ling off all classes; #pragma ling off all functions; #pragma link C++ class MyClass1; ..... #pragma link C++ class MyClassN; #endif ==================================== I have compiled the classes into a dll (developer studio 6) wich I load into an interactive root session with .L mylibrary.dll I then try to use them and root complains that it does not know them like: class, stuct, union or type MyClass1 not defined Same error occurs if I try: .class MyClass1 However if I load the dll again it says: warning in <Add>: class MyClass1 allready in in TClassTable Note: starting root I do get a funny message which says: Warning in <TWinNTSystem::setProgname>: wrong Program Path maybe that has something to do with my problems Valerie: this seems to be related to one of your latest messages to roottalk about loading dll's under windows but I am not realy sure. thansk for any help, cheers Armin ************************************************* * Dr. Armin Reichold | private: * * Research Officer | 17 Frys Hill * * University of Oxford | Oxford * * Particle & Nuclear Phys.
