Title: [solved]fpcup cross32-64 lcl compiling fail after fpc r24896(avx support).
Post by: parcel on June 15, 2013, 11:33:52 pm

I got new error with new fpc trunk r24896. Only happens 64bit cross compiling and 32bit compiler works ok. It maybe trouble on 64bit compiler, I guess.

Anyone have solve this problem?

Code: [Select]

Compiling graphmath.pp

function EllipseRadialLength(Rect : TRect; EccentricAngle : Extended) : Longint;
var
  a, b, R : Extended;
begin
  a := (Rect.Right - Rect.Left) div 2;
  b := (Rect.Bottom - Rect.Top) div 2;
  R := Sqr(a)*Sqr(b);
  if R <> 0 then
    R := Sqrt(R / ((Sqr(b)*Sqr(Cos(DegToRad(EccentricAngle/16)))) + // <--- Error
      (Sqr(a)*Sqr(Sin(DegToRad(EccentricAngle/16))))));
  Result := TruncToInt(R);
end;

          else
            internalerror(200310121);
        end;
      end;

Report to ugtracker with simple example that demonstrates this behavior (I guess a FAQ entry on internal error should be made so people don't ask anymore)

Thank you  :)

I temporary solve problem and more digging it  :D

Code: [Select]

function EllipseRadialLength(Rect : TRect; EccentricAngle : Extended) : Longint;
var
  a, b, R, c, d : Extended;
begin
  a := (Rect.Right - Rect.Left) div 2;
  b := (Rect.Bottom - Rect.Top) div 2;
  R := Sqr(a)*Sqr(b);
  if R <> 0 then begin // tweak
    c :=Cos(DegToRad(EccentricAngle/16));
    d :=Sin(DegToRad(EccentricAngle/16));
    R := Sqrt(R / ((Sqr(b)*Sqr(c))) +
      (Sqr(a)*Sqr(d)));
  end;
  Result := TruncToInt(R);
end;
