i'm getting following error on project links clang (verbose output):

according this question, linking -lc++ should fix issue, in case doesn't. i've managed reduce issue down flag, added llvm-config --ldflags:

-l/usr/local/cellar/llvm/3.6.2/lib 

any idea why flag causing error , how fix it?

i found problem: linking non-default stdlibs using -l/usr/local/opt/llvm/lib/. prepending -l/usr/lib, made sure os x's default stdlib goes above homebrewn version.
