Indeed I tried also : TString* s; // In the private area of my class s = new TString("small_test"); // In one of the initialisation // member functions char* ch=s->Data(); // In another member function. However, the last statement gives me an error message in ROOT "illegal pointer to class object". I also tried : char* ch=(char*)s->Data(); char* ch=(const char*)s->Data(); but nothing worked. Note that I have a small macro test.cc in which I create an object of my class, through which the above statements are invoked via the various member functions. The strange thing however is that when I type the above statements in by hand in my ROOT session, everyrhing looks o.k. Has someone any idea ?
