# Builds a Boost framework for iOS, iOS Simulator
|
|
# Creates a set of universal libraries that can be used on an iOS and in the
|
|
# iOS simulator.
|
|
#
|
|
# To configure the script, define:
|
|
# BOOST_VERSION: Which version of Boost to build (e.g. 1.72.0)
|
|
# BOOST_VERSION2: Same as BOOST_VERSION, but with _ instead of . (e.g. 1_72_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)
|
|
#
|
|
# 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.

|
--min-ios-version [num]
|
|
Specify the minimum iOS version to target. Defaults to $MIN_IOS_VERSION.
|
|
|
|
--clean
|
|
Just clean up build artifacts, but don't actually build anything.
|
|
|
|
--no-clean
|
|
Do not clean up existing build artifacts before building.
