Did you try with 7.8.3? Maybe it is already fixed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9309#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Judging from a `git log`, `make_exp` comes from external core. I guess you just have to remove `-fext-core` from your Cabal file. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9309#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

It was always out of date, no one was willing to give it any love, and there was no evidence of demand. You may want to consider using the GHC API instead.
