-- 2015-09-22 UPDATE --
Added command line args!
You can now specify if you want to build just for iOS or OS X, along with some other things.
Run boost.sh -h for more info.
Let me know if there are any other parameters that you think would be useful.

-- 2015-09-18 UPDATE --
Fixed script for iOS Simulator (Thanks @XMitja!)
• There is now a MIN_IOS_VERSION variable. Make sure you set this appropriately.

cleanup function now actually removes all build artifacts

Fixed updateBoost function to move the existing user-config.jam instead
of copying it. Copying it resulted in writing duplicate entries each time
the script was run.

NOTE: Currently does not build with bitcode. I will figure that one out when I get time.
I'm at the cusp of a product release though, so it might be a little while.
Just disable bitcode for your project for the time being.

-- 2015-08-26 UPDATE --
The resulting libraries from this script are currently not working for
the iOS simulator under Xcode 7 as of beta 6. I have an issue opened
with Apple about this. It does still work for physical devices though.
As soon as I figure out what the problem is, I will post an update.

-- 2014-12-29 UPDATE --

Updated to work with Boost 1.56, 1.57, and 1.58

Automatically choose the currently selected SDK for both iOS and OSX

Fixed a couple places where the wrong $XXX_DEV_CMD was being used

-- END UPDATE --

This is a modified version of Pete Goodliffe's original boost.sh build script,
(and a couple of other sources whom I can't remember)

The original version didn't work with the 64-bit iPhone Simulator,
and didn't build at all for OSX.

This works for Boost 1.56 and 1.57. If you need the version that builds 1.55 and older, use this revision:
  https://gist.github.com/faithfracture/c629ae4c7168216a9856/61be257e1c0839c85743777d0687becad9913bf7

I also ran into an issue where utf8_codecvt_facet.o existed in both the
program_options and filesystem libraries. When linking against the
framework, there was a missing vtable entry for it. Adding the step
in unpackArchive() that prepends the library name to the .o files
prevents this error.

I hope this keeps at least one other person from ripping their hair out.

Let me know if you find errors or have optimizations.

I will be updating this as often as necessary.

# Builds a Boost framework for iOS, iOS Simulator, and OSX.
# Creates a set of universal libraries that can be used on an iOS and in the
# iOS simulator. Then creates a pseudo-framework to make using boost in Xcode
# less painful.
#
# To configure the script, define:
#    BOOST_VERSION:   Which version of Boost to build (e.g. 1.58.0)
#    BOOST_VERSION2:  Same as BOOST_VERSION, but with _ instead of . (e.g. 1_58_0)
#    BOOST_LIBS:      Which Boost libraries to build
#    MIN_IOS_VERSION: Minimum iOS Target Version (e.g. 8.0)
#    IOS_SDK_VERSION: iOS SDK version (e.g. 9.0)
#    OSX_SDK_VERSION: OSX SDK version (e.g. 10.11)
#
# If a boost tarball does not exist in the current directory, this script will
# attempt to download the version specified by BOOST_VERSION. You may also
# manually place a matching tarball in the current directory and the script
# will use that.

    --boost-version
        Specify which version of Boost to build. Defaults to $BOOST_VERSION.

    -ios
        Build for the iOS platform. May be used in conjunction with -osx.
        If neither -ios nor -osx are specified, both are built.

    -osx
        Build for the OS X platform. May be used in conjunction with -ios.
        If neither -ios nor -osx are specified, both are built.

    --ios-sdk [num]
        Specify the iOS SDK version to build with. Defaults to $IOS_SDK_VERSION.

    --min-ios-version [num]
        Specify the minimum iOS version to target.  Defaults to $MIN_IOS_VERSION.

    --osx-sdk [num]
        Specify the OS X SDK version to build with. Defaults to $OSX_SDK_VERSION.

    --no-framework
        Do not create the framework.

    --clean
        Just clean up build artifacts, but don't actually build anything.

    --no-clean
        Do not clean up existing build artifacts before building.

	-- 2015-09-22 UPDATE --
	Added command line args!
	You can now specify if you want to build just for iOS or OS X, along with some other things.
	Run boost.sh -h for more info.
	Let me know if there are any other parameters that you think would be useful.

	-- 2015-09-18 UPDATE --
	Fixed script for iOS Simulator (Thanks @XMitja!)
	• There is now a MIN_IOS_VERSION variable. Make sure you set this appropriately.

	cleanup function now actually removes all build artifacts

	Fixed updateBoost function to move the existing user-config.jam instead
	of copying it. Copying it resulted in writing duplicate entries each time
	the script was run.

	NOTE: Currently does not build with bitcode. I will figure that one out when I get time.
	I'm at the cusp of a product release though, so it might be a little while.
	Just disable bitcode for your project for the time being.

	-- 2015-08-26 UPDATE --
	The resulting libraries from this script are currently not working for
	the iOS simulator under Xcode 7 as of beta 6. I have an issue opened
	with Apple about this. It does still work for physical devices though.
	As soon as I figure out what the problem is, I will post an update.

	-- 2014-12-29 UPDATE --

	Updated to work with Boost 1.56, 1.57, and 1.58

	Automatically choose the currently selected SDK for both iOS and OSX

	Fixed a couple places where the wrong $XXX_DEV_CMD was being used

	-- END UPDATE --

	This is a modified version of Pete Goodliffe's original boost.sh build script,
	(and a couple of other sources whom I can't remember)

	The original version didn't work with the 64-bit iPhone Simulator,
	and didn't build at all for OSX.

	This works for Boost 1.56 and 1.57. If you need the version that builds 1.55 and older, use this revision:
	https://gist.github.com/faithfracture/c629ae4c7168216a9856/61be257e1c0839c85743777d0687becad9913bf7

	I also ran into an issue where utf8_codecvt_facet.o existed in both the
	program_options and filesystem libraries. When linking against the
	framework, there was a missing vtable entry for it. Adding the step
	in unpackArchive() that prepends the library name to the .o files
	prevents this error.

	I hope this keeps at least one other person from ripping their hair out.

	Let me know if you find errors or have optimizations.

	I will be updating this as often as necessary.

	# Builds a Boost framework for iOS, iOS Simulator, and OSX.
	# Creates a set of universal libraries that can be used on an iOS and in the
	# iOS simulator. Then creates a pseudo-framework to make using boost in Xcode
	# less painful.
	#
	# To configure the script, define:
	# BOOST_VERSION: Which version of Boost to build (e.g. 1.58.0)
	# BOOST_VERSION2: Same as BOOST_VERSION, but with _ instead of . (e.g. 1_58_0)
	# BOOST_LIBS: Which Boost libraries to build
	# MIN_IOS_VERSION: Minimum iOS Target Version (e.g. 8.0)
	# IOS_SDK_VERSION: iOS SDK version (e.g. 9.0)
	# OSX_SDK_VERSION: OSX SDK version (e.g. 10.11)
	#
	# If a boost tarball does not exist in the current directory, this script will
	# attempt to download the version specified by BOOST_VERSION. You may also
	# manually place a matching tarball in the current directory and the script
	# will use that.
