Error: Operator is not overloaded

[IndianaJones]

Hi all,
Can someone explain what this error mean?
I have an equation like this, rel:=xy*(avalue[0] / avg);
That statement look fine to me but I cant figure it out?
Thanks.

Yes, it looks fine.
But important are types (declarations) of rel, xy, avalue[] and avg.

I get the same error message and it points to this line of code:

Code: [Select]

if StaticFail> MaxFF then PassAll := 1;

It seems to point to the (>) not being"overloaded". Does anyone know what this means and how I fix the error? I have no idea what "overloaded" refers to and searching hasn't given any explanation a novice can understand

You need to provide enough information about these identifiers.

[Ramijami]

Hi typo,

StaticFail is a basic counter that counts whether a certain comparison in a procedure passes or not, while MaxFF is what the user selects to set as maximum via a TEdit box.......both are integer type identifiers. I'm trying to understand what the purpose of "overload" is and how it relates to a seemingly simple comparison process. The explanation in the Free Pascal Referance guide has left me even more confused

[IndianaJones]

Have you ever use any dynamic array and setlength command in your programme?

Please create an minmal testcase exampple where the error occurs and attach it.
Without the actual code we can only guess.

Code: [Select]

if StaticFail> MaxFF then PassAll := 1;@ Ramijami
Are you sure that error message is related to ">" ? It can be related to ":=" as well. What type is "PassAll" ?

Hi typo,

StaticFail is a basic counter that counts whether a certain comparison in a procedure passes or not, while MaxFF is what the user selects to set as maximum via a TEdit box......

So the types of both MaxFF and StaticFail are integer ?

[Ramijami]

While doing a test example to post as requested by Bart I remembered that the free pascal reference referred to "two types" so thought I'd check to see if I used any of the Identifiers more than once. Found a similar "MaxFF" as the name of a textbox and changed it.......seems to have solved the problem (at least I'm not getting the error anymore). Thanks for the help, and my apologies for wasting your time on such a simple mistake on my part

I'm getting the same error for the following code:

  for i:=2 to f.size-1 do
    m:=m xor m[i-2];

m is pbytearray pointing to f

any help would be appreciated

MaxFF is declared as

  MaxFF: Integer ?

or as
  MaxFF: TEdit

the 2nd will not work. You can not use an object here.
yuo can get the TEXT via MaxFF.Text, and then need a StrToInt() to make it integer

I'm getting the same error for the following code:

Code: [Select]

  for i:=2 to f.size-1 do
    m[i]:=m[i] xor m[i-2];m is pbytearray pointing to f

Just quoting with code tags, to show what it looks like without forum changing it italic. I can't see what's wrong with the code. Maybe elsewhere? Can you try PByte instead of PByteArray?

I mean, my texture class has IFDEF so that same code works with Delphi and Lazarus. PByte is fpc way of things:

Code: [Select]

    {$IFDEF fpc}
    Data: PByte;
    {$ELSE}
    Data: PByteArray;
    {$ENDIF}

oh that works!! Thanks a lot

But some clarification of the difference between them would be great
