problem compiling an older Haskell program with GHC 6.6.1
hi, I am trying to compile paradox 1.0, an older (GHC 5) Haskell program, with GHC 6.6.1 (the Solaris 10 / x86 binary distribution). in case anyone else wants to try it, I put the paradox source code at http://www.cs.sunysb.edu/~stoller/out/paradox-1.0-casc.tar.gz in the Makefile, I deleted -package lang from HFLAGS, and added -v to it. then I typed make.

Au contraire - I think that is a great way to go about it, and it is how a lot of things get done. Meta-packages include desktop environments (e.g. KDE and Gnome) and the Linux kernel (e.g. linux-generic). However those projects clearly define which components make up the whole. We do not. There are the core packages that come with ghc and then there are all the other packages you can find on hackage. The 'extra' packages is just a bunch that used to be distributed with ghc. They're not intended to be canonical as far as I know. My understanding is that that 'extra' tarball is just a transitional thing provided for convenience until hackage gets up to speed. If people want to go and define some standard distribution of packages then that's another matter, but that's something that should be driven centrally rather than each of the various distro maintainers picking some arbitrary set of packages.

RE: Prefix form of unboxed tuple
| You might expect there to be a prefix form of the unboxed tuple: | | Prelude case (#,#) 1 2 of (# a , b #) - error $ show (a,b) | interactive:1:7: parse error on input `,' | | But there isn't. No real reason why not. If you write foo :: a - b - (# a,b #) foo x y = (# x, y #) then foo should work just fine. So what you want needs two things: * We would have to define a collection of such functions in the Prelude (see Data.Tuple, for the () functions). * We'd have to do is to make the parser understand '(#,,,#)'. Do add a feature request if you like. (And/or implement it!) It'd be a good rounding out thing. Another feature I'd like is for unboxed tuples to be more first class. For example, we don't currently allow f :: (# a, b #) - ... But there's no real reason why not; we could transform them away just before code generation. That would eliminate all special cases for unboxed tuples, except the constraints that apply to all unboxed types (notably: you can't instantiate a type variable with an unboxed type; unboxed types are strict). If you add a feature request, add that too! Simon ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
