Note omitting `-framework Foundation` makes no difference to the output.

The same error also occurs when launching GHCi with `-package foo` where foo uses Obj-C code through FFI. Template Haskell uses GHCi internally, so this means that we can't use Template Haskell with Objective-C FFI. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9277#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
