See if ping.pas has 'ping' in the uses clause somewhere...

unit Ping;

uses
  Windows, Messages, SysUtils, Classes, Winsock, Icmp;

There may be more than one uses clause per unit. Did you check that?

No there is only one USES Clause in this UNIT... this it the PING unit witch is called from main program called u_ping...

The u_PING uses ping in the uses clause but it should use it because it is needed by program...

How about doing a search on your app for the word Ping and see if it is being used in your code. I am not having this problem so I suspect your code is calling on in it some way that the compiler thinks is a recursive use of Ping. If you find nothing then try unistalling FPiette and install it as if you were installing it for the first time.

(since i dont know what the unit is, and haven't seen your code I'm kinda shooting in the dark here)

also you could try moving ping to a uses clause after implementation.

it also occures to me that maybe one of the units that ping has in it uses clause may also be using ping.  i think this could trigger that message.

other then that i also have no clue and would agree with The Crazy One and just start over with fresh code.

i would also try changing the program name to something other then u_ping, just to cover all bases

Delphi 6 has it's own ping unit, I guess...

I had this problem too, and found that it was caused by when I was creating the package.  You can't call the package the same thing as the unit itself.  ie: in my case the unit was slider.pas, and when I tried slider.dpk it would give me that error...so I used slid.dpk instead.
