# This script performs all of the steps needed to build a
# universal binary libcurl.framework for Mac OS X 10.4 or greater.
#
# Hendrik Visage:
#  Generalizations added since Snow Leopard (10.6) do not include the 10.4 SDK.
#
# Also note:
# 10.5 is the *ONLY* SDK that support PPC64 :( -- 10.6 do not have PPC64 support
# If you need to have PPC64 support then change below to 1
PPC64_NEEDED=0
# Apple does not support building for PPC anymore in Xcode 4 and later.
# If you are using Xcode 3 or earlier and need PPC support, then change
# the setting below to 1
PPC_NEEDED=0

# For me the default is to develop for the platform I am on, and if you
# desire compatibility with older versions then change USE_OLD to 1 :)
USE_OLD=0

# I also wanted to "copy over" the system, and thus the reason I added the
# version to Versions/Release-7.20.1 etc.
# now a simple rsync -vaP libcurl.framework /Library/Frameworks will install it
# and setup the right paths to this version, leaving the system version
# "intact", so you can "fix" it later with the links to Versions/A/...
