Re: [Haskell-cafe] How to get Cabal to spit out a .a library suitable for linking into C/Objective-C
Sorry about the belated response, but this shouldn't be a problem since it isn't going to be very helpful anyway! I've managed to follow the process described on this page: http://www.haskell.org/haskellwiki/Using_Haskell_in_an_Xcode_Cocoa_project to link Haskell code to a non-Haskell main program, via Xcode. You've probably already seen this, it's mostly about a few iterations of trial and error linking, to get the list of GHC library dependencies, which is what you need whether you're using Xcode or not. If you really need a single library with your code and all those dependencies, that may be technically feasible, though awfully tedious. The only clear problem I encountered while experimenting with it is that GHC run time options need ghc -rtsopts, so they're unavailable if your program isn't built by ghc. I believe I worked around that with a special rtsmain.o, could probably recover the details if that's of interest. Donn

Thanks for the pointer. I had already read this. I am looking for a non-trial-and-error mechanism for creating a statically linked .a file. It's Step 8 in the article. Thanks for your help. David
