Thanks for all the help. I pulled the latest today (0.7.3), and after a
few fix-ups, I got it built. Here are the tweaks I needed to build it for
SGI IRIX 6.5 using gcc.
==========
PROBLEM #1
==========
Ethereal doesn't use RPATH (see ld(1) for shared library linking on all
platforms that support it (e.g. SGI IRIX, FreeBSD ELF, etc.), just
Solaris it appears. Instead, ethereal recommends use of the
LD_LIBRARY_PATH hack which causes all sorts problems.
On SGI IRIX this is -rpath to the linker, on Solaris -R, on FreeBSD ELF
--rpath, etc.
SOLUTION: Slip in my linker flags when configuring ethereal so it can
find libgtk, libgmodule, libsnmp, etc. at run-time without
LD_LIBRARY_PATH:
env LDFLAGS="-rpath $HOME/software/gtk+-1.2.3/lib:$HOME/software/glib-1.2.3/lib:/usr/local/lib" configure --prefix=$HOME/software/ethereal-0.7.3 --with-gtk-prefix=$HOME/software/gtk+-1.2.3
BETTER SOLUTION: Modify configure to support RPATH for more platforms
than Solaris.
[NOTE: configure is generated from configure.ac and acinclude.m4, and
all the linking stuff is done by libtool. We don't recommend the
LD_LIBRARY_PATH hack - perhaps we did so in the past, but we don't do so
now.]
==========
PROBLEM #2
==========
__P not defined -- packet-snmp.c fails to build
(gcc version 2.95.1 19990816 (release), SGI IRIX 6.5.5f)
SOLUTION: Include gnuc.h -- it defines it

[NOTE: we don't use the __P macro ourselves; some of the SNMP libraries
might, but that's a bug in the libraries if they require you to define
__P in order to use them.]

Problem #1:
checking for GTK - version >= 1.2.0... 186062:./conftest: rld: Fatal Error: Cannot Successfully map soname 'libgtk-1.2.so.1' under any of the filenames /usr/lib32/libgtk-1.2.so.1:/usr/lib32/internal/libgtk-1.2.so.1:/lib32/libgtk-1.2.so.1:/opt/lib32/libgtk
no
*** Could not run GTK test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding GTK or finding the wrong
*** version of GTK. If it is not finding GTK, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location Also, make sure you have run ldconfig if that
*** is required on your system
***
*** If you have an old version installed, it is best to remove it, although
*** you may also be able to get things to work by modifying LD_LIBRARY_PATH
***
*** If you have a RedHat 5.0 system, you should remove the GTK package that
*** came with the system with the command
***
*** rpm --erase --nodeps gtk gtk-devel
configure: error: GTK+ distribution not found.

2. Patches to libpcap that may be necessary
On IRIX, older versions of the libpcap library use, in
"pcap_open_live()", the snapshot length passed in, without reducing it
to be less than or equal to the MTU of the interface. If the snapshot
length is larger than the interface MTU, IRIX will return an error; this
means that, for example, the Wireshark default snapshot length of 65535,
chosen so that all of the packet is captured, will not work.
Current versions of libpcap, from tcpdump.org, do not do so.
