Python4Delphi - Error with the function Py_XIncRef
«

November 08, 2018, 12:04:05 am »
Hello All
I have an error "unit1.pas(79,3) Error: Identifier not found "Py_XIncRef"
in th body of a function :
procedure TForm1.PythonDelphiVar2ExtGetData(Sender: TObject; var Data: PPyObject
);
begin
Data := FMyPythonObject;
Py_XIncRef(Data);
end;
I have the last versions of Lazarus and Python4Delphi, installed with p4dlaz.lpk. OS: Win10 x64
What can I do ? Anybody has an idea ?
Thank you for your help.
