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.

#===============================================================================

: BOOSTLIBS:="randomregexgraphrandomchronothreadsignalsfilesystemsystemdatetime":{BOOST_LIBS:="random regex graph random chrono thread signals filesystem system date_time"} : {IPHONE_SDKVERSION:=xcodebuild -showsdks | grep iphoneos | egrep "[[:digit:]]+\.[[:digit:]]+" -o | tail -1} : OSXSDKVERSION:=10.8:{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
