# Tiger/Leopard OSXBuild script
# ===========================
# By:		Gianluca Toso
# For:		aMule 2.2.x and SVN
# Descr:	multiplatform ed2k client
# URL:		http://www.amule.org/
# Needs:	gd2(no_x11 variant), gettext, libcryptopp, libgeoip(optional),
#		libupnp >= 1.6.6 (optional),
#		pkgconfig (needed to aMule configure to find libupnp),
#		and libpng(already requested by gd2)
#		from MacPorts (or you have to edit some things).
#		All these and the dependences must be Universal Binary
#		and compiled for the right OS!
# Notes:	On Leopard I initially used 10.5 SDK
#		and 10.4 as MACOSX_DEPLOYMENT_TARGET/macosx-version-min.
#		It worked (libiconv and libpng from MacPorts) and
#		there were no weak linked libraries.
#		Maybe it works even with 10.5 as deployment version,
#		but it excludes the G3 processors and I can't test.
#		But I think that here it makes no sense and doesn't bring
#		benefits, so now I use 10.4 SDK for Tiger/Leopard buils.
#		On Leopard try to append to port install commands:
#		+universal universal_target=10.4 universal_sysroot=/Developer/SDKs/MacOSX10.4u.sdk
#		(the same for upgrade commands).
#		It seems work even with only libcryptopp, gettext
#		and dependencies, but libpng is needed to run on Tiger,
#		gdlib seems not needed, but configure warns if it's missing:
#		cas uses it to create the Online Signature Image.

	Usage:
	 $0 [-d|-da|--fast|--fast-g4] [-ng] [-l] [-pNUM] [-rp]
	 $0 -h | --help

	Options:
		-l		compile only for Leopard and up (Leopard only).
		--leopard
		--fast		insanely optimize with -fast (G5 and up).
		--fast-g4	insanely optimize with -fast (G4 and up).
		-d		enable debug (WxMac and aMule).
		--debug
		-da		enable debug (only aMule).
		--debug-amule
		-ng		disable GeoIP.
		--no-geoip
		-pNUM		strip NUM leading components from patch file
				names.
		-rp		(re)package only.
		--repackage
		-h		prints help (this message).

	Environment:
		GEOIP	0 to disable IP2Country/GeoIP support
		VERSION	VERSION of aMule or SVN for daily snapshots
		PATCH	patch files to apply to aMule (separated by spaces)
		REV	SVN revision number (default the last)

	Example:
		VERSION=2.2.5 $0

	Notes:
		You Need gd2, gettext, libcryptopp, libgeoip(optional)
		and libupnp(>=1.6.6, optional) from MacPorts.
		All these and the dependences must be Universal Binary
		and compiled for the right OS.
		You may need to edit some things in the init function.
