Hi, after reading your mail I tried to add the following lines to the header of my class: #ifndef __MAKECINT__ typedef ostringstream ostrstream; typedef stringstreambase strstreambase; #endif /*__MAKECINT__*/ the #ifndef is needed to hide stringstreambase to rootcint because it seems not to know that class. It works well with gcc 2.96 but it doesn't with 3.32... Does exist a way to let the preprocessor know which is the current compiler version? Any suggestion would be greatly appreciated...
