# Builds a Boost framework for OSX
# Creates a set of universal libraries that can be used on an OSX
#
# To configure the script, define:
#    BOOST_LIBS:        which libraries to build
#    OSX_SDKVERSION:    OSX SDK Version. I.E. 10.8
#
# 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.

# make sure when running the .command we are in the current directory

: ${OSX_SDKVERSION:=`xcrun -sdk macosx --show-sdk-version`}
: ${XCODE_ROOT:=`xcode-select -print-path`}
: ${EXTRA_CPPFLAGS:="-DBOOST_AC_USE_PTHREADS -DBOOST_SP_USE_PTHREADS -stdlib=libstdc++"}

# 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

Yeah the original build script had libstd++, I think I was in the middle of updating it to libc++ and left it on github... glad you worked it out :D! I've fixing up this repo now.
