Hi
I upgrade Lazarus and FPT to current snapshot an I have problem

I can compile this procedure

procedure tForm1.MouseCLick(sender:tObject);
begin
end;
procedure tForm1.onnn(var onc : tNotifyEvent);
begin
  onclick:={$IFDEF ;
end;

compiler claim:
Error: incompatible types: got "Pointer" expected "<procedure variable type of procedure(TObject) of object; Register>"

when I try
onclick:={$IFDEF ;

till now everything were OK

This error message looks correct (at least if you are compiling in fpc or objfpc mode). onc is a procedure variiable, so @onc is the address of the procedure variable. You should simply do "onclick := onc", or possibly even

onclick := {$ifndef ; (since Delphi requires an @ to get
the contents of a procvar)

(at least if both onclick and onc are of type tnotifyevent and if tnotifyevent is a procvar type).

when I try onclick:={$IFDEF ;

In this case, the right hand side of the expression is a method, so you indeed need @ in FPC mode to get its address.

I port all my source to FPC (it compile in both Delphi and FPC) in many places I use {$IFDEF
and now all must be deleted or I don't know something

Several procvar bugs have been fixed lately. There have been no deliberate changes, although there may be some due to the fixes.

Definitely not all of them.

or I don't know something

If you compile your sources in Delphi mode (-Sd, or add {$mode delphi} at the top of each source file), you should not have to change much if anything. If you do have to change things, please report them as bugs.
