Anyhow, this is a regression I introduced when improving/fixing the recompilation logic: https://github.com/ghc/ghc/commit/52065e95c6df89d0048c6e3f35d6cc26ce8246f9 So to determine whether we need to recompile a module we need to track its "inputs", which includes the plugins the the module was compiled with. We decided to use the binary objects, `.so/.a` for packaged plugins, `.o` for local plugins, because they can only give false positives to determine whether the functionality of the plugin changes (`.hi` files can give false negatives). I guess I need to rethink how to handle local plugins... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16093#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
