Hi Paolo,
in cases like this where the nesting of #ifdef's is too deep
for rootcint (only one level), try excluding problematic headers
using #ifdef __CINT__ statements. For example, assume standards.h
gives problems, but it defines a few essential types:
...
...
#ifdef __CINT__
typedef unsigned int u_int;
#else
#include <standard.h>
#endif
...
...
In other cases one needs to use the -p (preprocess option). Often
this causes to much information to be provided to rootcint which
causes it to choke up. In some case a selective preprocessing
might be better. This can be done by the following pragma's in
the LinkDef.h file:
#pragma preprocess X11/
#pragma preprocess ZIP.h
The first pragma says to preprocess all headers in dir X11, e.g.
#include <X11/Xlib.h>
and the second says to only preprocess header ZIP.h.
Cheers, Fons.
