iphone - Social.framework not found -

i'm trying link facebook sdk 3.1 existing ios application. base of operations sdk 6.1, ios deployment target set 5.1.

i added social, accounts , adsupport framework project , set them optional in build phases > link binary libraries. tried manually link them -weak_framework in "other linker flags".

however, end with:

ld: framework not found adsupport clang: error: linker command failed exit code 1 (use -v see invocation)

what doing wrong?

thanks in advance!

edit: using xcode version 4.6 way!

the social framework new in ios6, if supporting ios5 has go target properties/build phases/link binary libraries , mark social framework optional shown in image
