# Trying to follow "Building Wireshark on SnowLeopard"
# given by Michael Tuexen at
# http://nplab.fh-muenster.de/groups/wiki/wiki/fb7a4/Building_Wireshark_on_SnowLeopard.html
#

DARWIN_MAJOR_VERSION=`uname -r | sed 's/\([0-9]*\).*/\1/'`

#
# To make this work on Leopard will take a lot of work.
#
# First of all, Leopard's /usr/X11/lib/libXdamage.la claims, at least
# with all software updates applied, that the Xdamage shared library
# is libXdamage.1.0.0.dylib, but it is, in fact, libXdamage.1.1.0.dylib.
# This causes problems when building GTK+, so the script would have to
# fix that file.
#
# Second of all, the version of fontconfig that comes with Leopard
# doesn't support FC_WEIGHT_EXTRABLACK, so we can't use any version
# of Pango newer than 1.22.4.
#
# However, Pango 1.22.4 doesn't work with versions of GLib after
# 2.29.6, because Pango 1.22.4 uses G_CONST_RETURN and GLib 2.29.8
# and later deprecate it (there doesn't appear to be a GLib 2.29.7).
# That means we'd either have to patch Pango not to use it (just
# use "const"; G_CONST_RETURN was there to allow code to choose whether
# to use "const" or not), or use GLib 2.29.6 or earlier.
#
# GLib 2.29.6 includes an implementation of g_bit_lock() that, on x86
# (32-bit and 64-bit), uses asms in a fashion ("asm volatile goto") that
# doesn't work with the Apple version of GCC 4.0.1, which is the compiler
# you get with Leopard+updates.  Apparently, that requires GCC 4.5 or
# later; recent versions of GLib check for that, but 2.29.6 doesn't.
# Therefore, we would have to patch glib/gbitlock.c to do what the
# newer versions of GLib do:
#
#  define a USE_ASM_GOTO macro that indicates whether "asm goto"
#  can be used:
#    #if (defined (i386) || defined (__amd64__))
#      #if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 5)
#        #define USE_ASM_GOTO 1
#      #endif
#    #endif
#
#  replace all occurrences of
#
#    #if defined (__GNUC__) && (defined (i386) || defined (__amd64__))
#
#  with
#
#    #ifdef USE_ASM_GOTO
#
# Using GLib 2.29.6 or earlier, however, would mean that we can't
# use a version of ATK later than 2.3.93, as those versions don't
# work with GLib 2.29.6.  The same applies to gdk-pixbuf; versions
# of gdk-pixbuf after 2.24.1 won't work with GLib 2.29.6.
#
# Once you've set this script up to use the older versions of the
# libraries, and built and installed them, you find that Wireshark,
# when built with them, crashes the X server that comes with Leopard,
# at least with all updates from Apple.  Maybe patching Pango rather
# than going with an older version of Pango would work.
#
# The Leopard Wireshark buildbot uses GTK+ 2.12.9, Cairo 1.6.4,
# Pango 1.20.2, and GLib 2.16.3, with an unknown version of ATK,
# and, I think, without gdk-pixbuf, as it hadn't been made a
# separate library from GTK+ as of GTK+ 2.12.9.  Its binaries
# don't crash the X server.
#
# However, if you try various older versions of Cairo, including
# 1.6.4 and at least some 1.8.x versions, when you try to build
# it, the build fails because it can't find png_set_longjmp_fn().
# I vaguely remember dealing with that, ages ago, but don't
# remember what I did; fixing *that* is left as an exercise for
# the reader.
#
# Oh, and if you're building with a version of GTK+ that doesn't
# have the gdk-pixbuf stuff in a separate library, you probably
# don't want to bother downloading or installing the gdk-pixbuf
# library, *and* you will need to configure GTK+ with
# --without-libtiff and --without-libjpeg (as we currently do
# with gdk-pixbuf).
