Did you figure out what you need to know?

Sadly, no.

If not, I would suggest asking this same question but on StackOverflow (assuming you haven't already asked there).

I missed this question the first time around. Sorry. I don't have a canned answer to your question, but on the wxHaskell team we have recently been working on (ab)using Cabal to produce shared libraries, and almost everything is just as applicable to static libraries. It's not all working yet, but some of the following pointers might help you to understand how to make Cabal linking configurable. http://wewantarock.wordpress.com/2010/11/03/building-a-shared-library-in-cab... http://sourceforge.net/mailarchive/message.php?msg_id=28520475 http://sourceforge.net/mailarchive/message.php?msg_id=28665900

Great suggestion. Thanks!

Haskell code such that the code can be part of C and/or Objective-C code such that all the Haskell dependencies are rolled into a .a file and can be linked by a normal C linker (e.g., ld).

I've been through http://haskell.org/ghc/docs/6.12.2/html/users_guide/ffi-ghc.html#using-own-m... and the associated linked, but I'm unable to find out the Cabal incantation to output a library that's linkable into my other code. Any pointers or examples would be greatly appreciated.

Thanks,

David
