ghci -package Foo ghc-6.8.3: unknown symbol `_iceExePath' Loading package Foo-0.1 ... linking ... ghc-6.8.3: unable to load

Hello, I'm having some trouble correctly linking to externally generated object code when using ghci. I'm loading a Cabal package Foo, that has already been successfully installed: package `Foo-0.1' I have a file Bar.o which contains the definition of _iceExePath:

nm ./Bar.o ... U _ProcessInformationCopyDictionary 000000a0 b _exepath 00000000 T _iceExePath U _kCFBundleExecutableKey ...

The documentation at http://www.haskell.org/ghc/docs/6.8.3/html/users_guide/ghci-invocation.html#... says that: "GHCi can also load plain object files (.o or .obj depending on your platform) from the command-line. Just add the name the object file to the command line." So, I've tried both of these command lines:

ghci ./Bar.o -package Foo ghci -package Foo ./Bar.o

but ghci still can't find _iceExePath, and the same error occurs. I'm using GHC 6.8.3. I'm not sure how to proceed and would appreciate any advice. Thanks for your help, Ryan Wisnesky
