Re^2: XS Modules: Dependencies

in reply to Re: XS Modules: Dependencies
in thread XS Modules: Dependencies

Yes, i know that. But XS is actually needed since i want to write a OO interface to a (non trivial) Win32 C API.
(and for sure, i know how to walk! :) )
so for now i have the following code

Foo-Bar/typemap

TYPEMAP

PBar         T_PTROBJ
[download]

Foo-Bar/Bar.xs

typedef struct __Bar {
// ...
} Bar, *PBar;

MODULE = Foo::Bar        PACKAGE = Foo::Bar

PBar
new(class);
    const char* class
 PREINIT:
     PBar        retval;
 CODE:

     New(0, retval, 1, Bar);

     RETVAL = retval;
 OUTPUT:
     RETVAL
[download]

Foo-Bar-Builder/typemap

TYPEMAP
PBarBuilder         T_PTROBJ
PBar         T_PTROBJ
[download]

Foo-Bar-Builder/Builder.xs

typedef struct __BarBuilder {
// ...
} BarBuilder, *PBarBuilder;


MODULE = Foo::Bar::Builder        PACKAGE = Foo::Bar::Builder

PBarBuilder
new(class);
    const char* class
 PREINIT:
     PBarBuilder retval;
 CODE:

     New(0, retval, 1, BarBuilder);

     RETVAL = retval;
 OUTPUT:
     RETVAL

MODULE = Foo::Bar::Builder        PACKAGE = Foo::Bar::BuilderPtr

PBar
create(void);
 PREINIT:
     PBar retval;
 CODE:

    RETVAL = retval;
 OUTPUT:
     RETVAL
[download]

so, the question is: do i have to call Foo::Bar::new inside Foo::Bar::Builder::create? or do i have to reimplement the new function of Foo::Bar::new inside Foo::Bar::Builder, or what?
so, the Foo::Bar::new is now defined inside the Foo/Bar/Bar.dll, and the C compiler does not know, where to find it. I guess it does not help to link against Foo\Bar\Bar.lib, since the dll just exports

1    0 00001000 _boot_Foo__Bar
2    1 00001000 boot_Foo__Bar

Get the point?

It looks like you're doing too much in XS and not enough in perl. Why can't you have your C-allocating routines just return a numified pointer and let perl do all of its own OO stuff? I also feel like I'm getting lost somewhere in your confused code. I'd really like to point you at Simon Cozen's Embedding and Extending Perl book. Or Damian Conway's Object Oriented Perl. `sub new { my ( $class ) = @_; my $c_ptr = Foo::Bar::_new_or_whatever(); return bless \ $c_ptr, $class; }` [download]	[reply] [d/l]
