Hello,
On Windows, I'm trying to serialize an object to JSON in Delphi 7, using
FPC functions linked in a shared lib.
I'm sendind a small demo in attached. To test it is very easy:
1. compile the libfpserializer.lpr file;
2. copy the generated lib to the demo/lazarus_ok folder;
3. copy the generated lib to the demo/delphi_bug folder;
Now, compile the Lazarus project in "lazarus_ok" folder, compile, run and
see that it works fine. Now, compile the
Delphi project in "delphi_bug" folder, compile, run and see a bizzare bug
that kills the app.
So, in Delphi 7, its possible to consume a DLL written in Free Pascal?
You cannot mix Delphi objects with FPC objects.
They have a different memory layout, the RTTI is different etc.
So what you try to do is not possible.
I have somewhere a version of TJSONStreamer which uses SuperObject to write the
JSON.
If you want I can try to dig it up somewhere.
Michael.
