I use this project to build boost for iOS: https://github.com/danoli3/ofxiOSBoost/blob/master/scripts/build-libc%2B%2B

My client project is set with:

IPHONEOS_DEPLOYMENT_TARGET = 7.0
Base SDK = 9.2

I get the following warnings when I link against the boost framework. 

ld: warning: object file ((error_code.o)) was built for newer iOS version (9.2) than being linked (7.0)
ld: warning: object file ((future.o)) was built for newer iOS version (9.2) than being linked (7.0)
ld: warning: object file ((once.o)) was built for newer iOS version (9.2) than being linked (7.0)
ld: warning: object file ((thread.o)) was built for newer iOS version (9.2) than being linked (7.0)

How do I change the deployment target for boost bjam? or is there a way to fix these warnings?

Add the flag "-miphoneos-version-min=7.0" to the user-config.jam like this in the script you have referenced.

updateBoost()
{
echo Updating boost into $BOOST_SRC...

cp $BOOST_SRC/tools/build/example/user-config.jam $BOOST_SRC/tools/build/example/user-config.jam.bk

cat >> $BOOST_SRC/tools/build/example/user-config.jam <<EOF
