I'm on OS X Leopard 10.5.8, using ghc 6.10.4 from Haskell Platform. I'm trying to get a static .a library, callable from C, that I can use in an OS X Cocoa program. I've tried a very simple case (the one in Haskell Wiki Tutorials,"calling haskell from C") I've managed to make a Mac Cocoa application by adding the ghc generated .o program, plus adding one by one the needed Haskell libraries for "symbol not found" to my Xcode project. There should be a better way. I've tried just about everything I could find on creating Haskell libraries, with no joy. My latest try is to use Cabal, following advice found both in "How to write a Haskell program" and the Cabal users guide. My output from cabal -v configure tells me, among others: --- Reading installed packages... /usr/bin/ghc-pkg dump --global /usr/bin/ghc-pkg dump --user Reading available packages... Resolving dependencies... There is no installed version of base --- But when I do ghc-pkg dump --global it appears base is listed. Apparently, "no installed version of base" short circuits the whole process. Any suggestions, pointers to reading, whatever will be appreciated.
