Title: Array of array of array problem...
Post by: Fred vS on April 09, 2014, 01:53:25 am

Hello.
I have some trouble with array :

Code: [Select]

type
...
  TDArFloat = array of cfloat;
   TDArPARFloat = array of TDArFloat;
  TDArIARFloat = array of TDArPARFloat; 

....
var
mymultiarray : TDArIARFloat ;
 
When i use that code with fpc 2.7.1 => perfect, no problem :

Code: [Select]

setlength(mymultiarray,1) ;
 setlength(mymultiarray[0], 1) ;
  setlength(mymultiarray[0].[0],1) ;
 
But with fpc 2.6.2 i have that error  message :

Quote

setlength(mymultiarray[0].[0],1)
 Error: Illegal qualifier

What must i do to be fpc 2.6/2.7 compatible ?

Many thanks.

Fred

Maybe SetLength(mymultiarray[0, 0], 1);?

Code: [Select]

SetLength(mymultiarray[0, 0], 1);=>

Quote

Error: Incompatible types: got "Set Of Byte" expected "Int64"

From an example from the docs (http://www.freepascal.org/docs-html/ref/refsu18.html#x42-460003.3.1):
SetLength(mymultiarray, 1, 1, 1);

@ engkin : Many thanks.

Aaargh, lot of code to change and...
 with SetLength(mymultiarray, 1, 1, 1), it set length for each array.
With the fpc 2.7.1 syntax, you can set only the length of last array.

Or maybe does it exist something like : SetLength(mymultiarray, -1, -1, 3) but i do not find it in doc  ;)

Code: [Select]

setlength(mymultiarray[0].[0],1)

Why the "." ?

Should it not be

Code: [Select]

setlength(mymultiarray[0][0],1)

@ Martin_fr => more than ever => brillantissimo  ;)

Code: [Select]

setlength(mymultiarray[0][0],1)
Did the trick  ;D

Many thanks.

(and now re-change all my code  :-X )

PS : Strange that setlength(mymultiarray[0].[0],1) works perfectly with 2.7.1.
