need help missing header files with gcc

Hi guys, I was wondering if someone can help me understand what is going on.
I have a macbook running tiger 10.5.8 and am using gcc v4.0.1. Right now I am trying to do some programming with raw sockets but when I compile it says some of the header files are not available ie.


I dont' know what to do as I've updated my xcode just an hour a go to see if that might have been the problem but it isn't. SO i was wondering if someone had any recommendations.

Right now I am trying to get gcc4.4.3 downloaded via "sudo port install gcc 423" any help would be great. thanks

I won't pretent to the know the answer, but I did notice that searching Google shows that you are the first to ask about packet.h. It looks like OS X doesn't have that particular .h file, so it is likely a platform specific thing. Perhaps you want the socket.h file?

Apple seems to have a lot of possibilities. Perhaps some of the Apple docs will lead you to the right answer for your project; "Introduction to CFNetwork Programming Guide", "Setting Up Socket Streams", "OpenPlay and NetSprocket".
