# Builds a Boost framework for the iPhone.
# Creates a set of universal libraries that can be used on an iPhone and in the
# iPhone simulator. Then creates a pseudo-framework to make using boost in Xcode
# less painful.
#
# To configure the script, define:
#    BOOST_LIBS:        which libraries to build
#    IPHONE_SDKVERSION: iPhone SDK version (e.g. 5.1)
#
# Then go get the source tar.bz of the boost you want to build, shove it in the
# same directory as this script, and run "./boost.sh". Grab a cuppa. And voila.

: ${IPHONE_SDKVERSION:=`xcodebuild -showsdks | grep iphoneos | egrep "[[:digit:]]+\.[[:digit:]]+" -o | tail -1`}
: ${OSX_SDKVERSION:=10.8}
: ${XCODE_ROOT:=`xcode-select -print-path`}
: ${EXTRA_CPPFLAGS:="-DBOOST_AC_USE_PTHREADS -DBOOST_SP_USE_PTHREADS -std=c++11 -stdlib=libc++"}

# The EXTRA_CPPFLAGS definition works around a thread race issue in
# shared_ptr. I encountered this historically and have not verified that
# the fix is no longer required. Without using the posix thread primitives
# an invalid compare-and-swap ARM instruction (non-thread-safe) was used for the
# shared_ptr use count causing nasty and subtle bugs.
#
# Should perhaps also consider/use instead: -BOOST_SP_USE_PTHREADS

I haven't used boost in a while and don't have the capacity at the moment to update the script. There has been an oldish comment referencing another script that is working so might have more luck with that: https://gist.github.com/rsobik/7513324?permalink_comment_id=1272149#gistcomment-1272149
