You want conditional configurations in the .cabal file. See http://www.haskell.org/cabal/release/cabal-latest/doc/users-guide/authors.html#configurations For the OS issue you can do something like if os(windows) Build-depends: canlib-windows else Build-depends: canlib or whatever. For user-selectable programs, create some flags and use the flags to specify which executables are buildable. Then the user can just pass a flag to cabal install and get the executables they want. -Brent _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
