I forgot to included it as part of the tar.gz image in Ethereal 0.7.9.
The next release will have it. Here's the file.

After much work and toil, Craig Rodrigues was able to compile libpcap and Ethereal
on AIX 4.3.2. His odyssey is document in various e-mails at
http://ethereal.zing.org/lists/ethereal-dev/199911/

Here are a few excerpts.

I believe glib and gtk+ should both be compiled with xlc_r. I haven't
compiled on AIX in a long time, but I think it's because glib is including
pthread stuff, so the re-entrant C library, libc_r, is needed. 


Compiler Invocation

When compiling a multi-threaded program, you should invoke the C compiler
using one of the following commands:

xlc_r
    Invokes the compiler with default language level of ansi.
cc_r
    Invokes the compiler with default language level of extended.


These commands ensure that the adequate options and libraries are used to be
compliant with the X/Open Version 5 Standard. The POSIX Threads
Specification 1003.1c is a subset of the X/Open Specification.

The following libraries are automatically linked with your program when using these commands:

libpthreads.a
	    Threads library.
libc.a
	    Standard C library


For example, the following command compiles the foo.c multi-threaded C source file and produces the foo executable file:

cc_r -o foo foo.c

See the cc command for more information about C For AIX.

Hi,

After much sweat and toil, I have managed to get gtk 1.2.6 to
compile and not dump core under AIX.  The solutions were to
(1) apply the attached patch to the configure.in in the glib-1.2.6
subdirectory

(2)  In the file gtk+-1.2.6/gtk/Makefile, add a link flag -lgdk to link
in gdk.

I have submitted (1) to the gtk-devel mailing list where it has been
accepted.  (2) is an uglier problem, but for now, adding -lgdk by hand
seems to work.

Now I have a problem....I compiled gtk, and that works.
I compiled ethereal (after some minor mods), and it starts,
but when I click on Capture -> Start, I get:

"There are no network interfaces that can be opened."

I am running as root, so I don't think permissions are a problem.

Any ideas?

Thanks.

Hi,

OK, I'm getting closer and closer to this working on AIX.

Things I've done:

(1) In a bunch of places in the code I removed '//' style C++ comments
which the IBM C compiler didn't like.

(2) I also found some places in the code like:

enum some_enum {  FOO, BAR, };

IBM C did not like the trailing "," after BAR.

(3) In packet-ipv6.h, IPV6_VERSION is defined, but that is already
defined in <netinet/in.h> on AIX 4.3, so for now I just commented that out.

(4) in packet-afs.c, when it sucks in <netinet/in.h>,  in.h sucks in
<sys/machine.h> which defines LITTLE_ENDIAN.  This conflicts with
LITTLE_ENDIAN in globals.h.  So what I did was, in globals.h, I added:

#ifdef HAVE_NETINET_IN_H
#include <netinet/in.h>
#endif

So after doing all these things, I can compile ethereal and run it.  
I can list the
correct network interfaces on my system: lo0 and en0.  However,
when I start capturing packets on en0, they are all of the protocol type
"TRMAC" and "TR".  The only problem is, I'm not on a Token Ring network.

Any ideas?

No. Time        Source                Destination           Protocol   Info
1 0.000000    0a:30:a1:08:00:45     06:74:60:08:00:5a     TR   Token-Ring Unknown

---------------------
It turns out that libpcap was using IFT_* numbers instead of DLT_* numbers for
link types. That has been fixed

Hi,

I have managed to successfully compile and use the latest
snapshot of libpcap under AIX using DLPI.  bpf is majorly
brain-dead under AIX, and very unsupported.  Rather than
find all the bugs in AIX's bpf, I decided to try using
dlpi, which is officially supported.

The first step is to get the setup right.  To determine if
you have the dlpi driver loaded correctly, type:
strload -q -d dlpi

If the result is:
dlpi: yes

then you are ready to use dlpi.

If you get:
dlpi: no

Then you need to type:
strload -f /etc/dlpi.conf

Check again with strload -q -d dlpi that the dlpi driver is loaded.

I had to make one minor code change to pcap-dlpi.c.  Maybe someone
can explain it to me, because I am not familiar with dlpi or
streams programming.  It took me hours to figure this out, because
I'm not familiar with dlpi.

In pcap-dlpi.c, lines 316-320:
#if !defined(HAVE_HPUX9) && !defined(HAVE_HPUX10_20) && !defined(sinix)
       if (dlbindreq(p->fd, 0, ebuf) < 0 ||
	   dlbindack(p->fd, (char *)buf, ebuf) < 0)
	    goto bad;
#endif

I changed it to:
#if !defined(HAVE_HPUX9) && !defined(HAVE_HPUX10_20) && !defined(sinix)
       if (dlbindreq(p->fd, 1620, ebuf) < 0 ||
	   dlbindack(p->fd, (char *)buf, ebuf) < 0)
	    goto bad;
#endif

I picked the number 1620 out of thin air.  The second parameter
to dlbindreq() sets the value of dl_sap.  This dl_sap
value is then passed along to the DLPI driver through
the DL_BIND_REQ primitive.  I guess that it cannot be 0 under
AIX, but I'm not sure.

If someone knows anything about DLPI, I'd appreciate a clarification.
Basically, I am just using the DLPI specification at:
http://www.opengroup.org/onlinepubs/009638599/ which is pretty good.
The AIX documentation is not so well written.

But basically, after I fixed up pcap-dlpi.c, I managed to get libpcap
working under AIX.  This enabled me to successfully run Ethereal,
ie. all the packets on my Ethernet network correctly showed up
as Ethernet and not Token Ring in the Ethereal screen.

YAY!
