Hi guys,

I am trying to compile my code which is compatible with Delphi and FPC 2.5.1+, but when I try to compile on Mac OS X with 2.4.4 I have error message:

Error: Illegal type conversion: "Set of TMyEnum" to "Byte"

and

Error: Illegal type conversion: "Byte" to "Set of TMyEnum"

The code is following:

type TMyEnum = (meFirst, meSecond);
type TMyEnumSet = set of TMyEnum;
var myEnum:TMyEnumSet;
    b:byte;
...
  b := byte (myEnum);

or

 myEnum := TMyEnumSet(b);

What is wrong on this for 2.4.4?

Thanks.

ff.

It works in FPC 2.5.1+ because of this change: http://wiki.freepascal.org/User_Changes_Trunk#Sizes_of_sets_in_TP.2FDelphi_mode

You can add {$packset 1} to your source file get the same behaviour in 2.4.4
