The dictionary generated from my class Drag has some sort of problem
with the destructor:
g++ -fPIC -I/usr/X11R6/include -I/usr/include/g++ -I/oscar/public/root/include -c dictionary.cc
dictionary.cc: In function `int G__Drag_DragcLcLwADrag_9_0(struct G__value *, char *, struct G__param *, int)':
dictionary.cc:319: aggregate value used where an integer was expected
/* Drag */
static int G__Drag_DragcLcLwADrag_9_0(G__value *result7,char *funcname,struct G__param *libp,int hash) {
G__letint(result7,105,(long)((Drag*)(G__getstructoffset()))->Drag::~Drag());
return(1);
}
Note that this compiler error does NOT occur when Drag.h is rootcinted
separately. Only when I am attempting to create a rootcint dictionary
of my entire 40-file source tree at once.
