you should probably add some more information, like how you invoked the build process ... – user23573 Sep 17 '15 at 18:15

I am doing a manual build with ./bootstrap.sh ./b2 install. I tried editing the boost makefile to supress the warning with cflags = -w -O3 -Iinclude -isystem $(BOOST_ROOT) -Wno-unused-local-typedefs but doesnt seem to work. – C.J Sep 18 '15 at 17:29

These are warnings. This is pretty normal when building boost. Look at the [documentation](http://www.boost.org/doc/libs/1_59_0/more/getting_started/unix-variants.html#boost-root-directory) in paragraph § 4.1. – user23573 Sep 18 '15 at 18:42
