RE: Failed to install Gtk2 module on windows
I run your script. While running Makefile.PL for Glib, it claims no glib
library was included:

These functions are from cairo, so I modified pangocairo.pc:
Libs: -L${libdir} -lpangocairo-1.0 -lcairo
and compiled again, but the error still occur.
The pkg-config seems working well:
pkg-config --libs pangocairo-LD:/Gtk-2.0/lib -lpangocairo-1.0 -lpango-1.0
-lcairo

Thanks!!!
The problem is perl-Cairo's import library interfere with Cairo's (the way
MakeMaker handles them). Copy attached to the directory that contains the
gtk+-bundle, and rebuild Cairo, then try building Pango again.

RE: generic refcounted object perl binding
Another question about wrapper design, in function gperl_new_object() where an
new wrapper is newly created:
..obj = (SV *)g_object_get_qdata (object, wrapper_quark);
if (!obj) {..// created a hashobj = (SV *)newHV ();
_gperl_attach_mg (obj, object);g_object_ref (object);
// created a SV wrapper for the hashsv = newRV_noinc (obj);
sv_bless (sv, stash);..}..
Why don't bless the HV directly, but instead creating another SV wrapping the
HV, and bless that SV instead?Why use noinc to create the wrapper? Shouldn't
the SV wrapper holding a reference for HV?
Thanks!

This is so that we always hand out an SV referencing the same HV for the
same GObject. Glib::Object allows you to store your own data directly
in the referenced hash, and this mechanism makes sure that you will find
this data again when you look at the same GObject later, with no need to
store the SV in between.

generic refcounted object perl binding
Hi, everyone!
I'm asking a question about how to wrapping a refcounted class inside perl. I
ask the question here because Gtk is such kind of system.
I have some experience on embedding perl in C++, but have little knowledge on
perl XS, and I found perldoc perlxs really puzzled.
Firstly, I have an simple refcounted C++ base class like this:
class Referenced {public:Referenced():refcnt(0) { }
virtual ~Referenced() {}
void refInc() { refcnt++; }
void refDec() {if (--refcnt=0) delete this;}
protected:int refcnt;};
In my wrapper, I want to have following functions:- able to construct my object
within perl, like My::Class-new();- able to construct my object in C++, and
pass it to perl sub as argument;- handle ref count correctly;
So, is these things correct for my XS:
Referenced::new(class)PREINIT:const char* class;Referenced*
obj;SV* obj_wrap;SV* sv;
CODE:// create objectobj = new Referenced;
obj-refInc();// store pointer as unsigned int?obj_wrap
= newSV(0);sv_setuv(obj_wrap, (uv)obj);
// we always wrap 2 layers SVs for a class? Should I do these things
manually?sv = newSVrv(obj_wrap, class);RETVAL = sv;
OUTPUT:RETVAL
// is this correct?// I don't really understand when would Perl do automatic
scalar conversion, and when should I manually do that.Referenced::DESTROY(self)
PREINIT:Referenced* self;CODE:self-refDec();
