Actually... none. :)
If you want portability, simply don't use D2005 syntax.
Hmmm... very nice advice. :)
Write it in D7 and compile it everywhere.
To my knowledge there are no plans for post-D7 support. The whole point is
compability with Delphi.NET, and there is not much interest in that anyway.
So, may I conclude that FPC is targetting D7 language compatibility? That's
sound fair enough to me, and -thanks God- I can live with that. :)
Is the D7 compatibility has been reached fully or partially or still under
development? How far the compatibility of FPC v.2.0 with D7? Is there any
docs
at least the (com) implements keyword and the variant IDispatch
compiler support is still missing, whereas someone wanted to tell me the
behaviour of the latter, but mysteriously vanished. Someone else started
to implement the implements keyword, I think.
For IDispatch, its something like if there is a variant (containing
a ??? IUnknown reference) used in an expression, and then a dot follows,
then pass the actual method name of the method called via idispatch to
the interface in the variant.
It's like
i: IUnknown;
v: Variant;
i := mooo;
v := i;
v.Bla; --- magical auto-cast to IDispatch and passing 'Bla' to be
called to Invoke
HRESULT Invoke(
DISPID dispIdMember,
REFIID riid,
LCID lcid,
WORD wFlags,
DISPPARAMS FAR* pDispParams,
VARIANT FAR* pVarResult,
EXCEPINFO FAR* pExcepInfo,
unsigned int FAR* puArgErr
);
Use GetIDsOfNames or the object's documentation to obtain the dispatch
identifier.

Pretty sure I'm missing something (like for example what the dispids and
'dispatch interfaces' are for and such), and it makes no sense if we
dont have an user who uses IDispatch (since it then cant be really
tested, plus, on linux - where I am -, there are close to no apps that
support that IDispatch interface at all). Someone please fill in the
gaps.
(Plus, I hated IDispatch when I was using delphi. Very good for
variant-based runtime-only errors, hard to track down.)
explain about this issue? Because I still failed to compile my D7 codes under
FPC 2.0. It's an D7 codes utilizing dbExpress components.
Hmm, well, more info please :)
