Undefined symbols for architecture x86_64 with llvm and clang

I have a cpp file which is including some header files of OCLint. Those header files internally includes clang and llvm headers like AST,ASTMatchers etc...

I have already specified the required header search path in the Build Settings as :-

../Downloads/clang+llvm-3.3-x86_64-apple-darwin12/include

But when I build I get the following error :-

Undefined symbols for architecture x86_64: "llvm::RefCountedBaseVPTR::anchor()", referenced from: vtable for clang::ast_matchers::internal::matcher_isPublic0Matcher in File.o vtable for clang::ast_matchers::internal::matcher_isProtected0Matcher in File.o vtable for clang::ast_matchers::internal::matcher_isPrivate0Matcher in File.o vtable for clang::ast_matchers::internal::matcher_hasAnyTemplateArgument0Matcher in File.o vtable for clang::ast_matchers::internal::matcher_ignoringImpCasts0Matcher in File.o vtable for clang::ast_matchers::internal::matcher_ignoringParenCasts0Matcher in File.o vtable for clang::ast_matchers::internal::matcher_ignoringParenImpCasts0Matcher in File.o ...

Did I forget to include some header search path ?

Probably forgot to add dependent library. Add these and try again
