[Winpcap-users] Winpcap in Intanium machine

[Gianluca Varenni]

Porting to itanium is not exactly trivial.

Driver: you must use the WDK to compile the driver, and you will need to 
follow the directions at

http://www.winpcap.org/docs/docs_41b5/html/group__compilation.html

*and* modify the "CompileDriver.bat" script. You might need to make some 
mods here and there. There are a number of #ifdef's for x64 (_AMD64_) that 
should be modified for IA64 too. Finally, if you run on 
Vista/2008/Win7/2008R2 IA64, I'm pretty sure the driver should be signed in 
order to even load.

User level components: in this case you should be able to use WOW64 and use 
the standard 32bit DLLs that are already shipped.

But if I'm not getting success on compiling of winpcap in my machine, will
be futile to search a itanium one. I tried to use the PRJ dir with visual
studio, but didn't work. I saw the makefile that appears to use gcc, but i
don't know where to start. There's a lots of .bat files.

The only option that I found that appears to be ready to capture under
itanium is the Network Monitor 3.3 from Microsoft with their API. But I'm
not sure to consider this option.

My *guess* would be that it doesn't, as I think current versions of
WinPcap support x86-64, so the code is at least 64-bit clean.  I think
it has a compiler that translates the BPF filter program to machine
code; that compiler supports 32-bit x86 (and there's an x86-64 version
originally done for FreeBSD, which WinPcap might have picked up), but
there isn't one for Itanium, so, if there's no #ifdef, you might have
to disable that.  (BPF still works, it just runs interpretively.)

No, because WinPcap includes kernel-mode code (because it requires it,
in order to tap into the networking stack).
