Hi, I do not know why, my ghc 7.2.1 does not seem to support DeriveRepresentable. I compiled the ghc 7.2.1 myself by ghc 7.0.4. All options default. $ ghc Types/TopTalkerRecord.hs Types/TopTalkerRecord.hs:2:14: Unsupported extension: DeriveRepresentable $ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.2.1 -- 竹密岂妨流水过山高哪阻野云飞

All I can find about DeriveRepresentable is a patch submitted in April [1]. However, it seems [2] that it has been renamed to DeriveGenerics [1]: http://www.haskell.org/pipermail/cvs-ghc/2011-April/061666.html [2]: http://code.galois.com/cgi-bin/gitweb?p=type-naturals/base.git;a=commitdiff;... -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com

There's no extension of that name in 7.2.1. Do you mean DeriveGeneric? Cheers, Andres

I do not know. I will try that. I got the name from http://www.haskell.org/haskellwiki/Generics. -- 竹密岂妨流水过山高哪阻野云飞

Oh, right, I see that some things on that page need updating; I'll do so. Thanks, Pedro On Tue, Nov 1, 2011 at 09:33, Magicloud Magiclouds < magicloud.magiclouds@gmail.com> wrote:

Thank you. I saw the page was updated. So I followed the document. And got stuck again. Copying the code and compile, I got: 25instance (GSerialize a) => GSerialize (M1 i a) where 26 gput (M1 x) = gput x test.hs:25:40: `M1 i a' is not applied to enough type arguments The first argument of `GSerialize' should have kind `* -> *', but `M1 i a' has kind `(* -> *) -> * -> *' In the instance declaration for `GSerialize (M1 i a)' -- 竹密岂妨流水过山高哪阻野云飞

Thanks, you spotted another mistake on that page, I corrected it. Make sure to have a look at the functions in http://hackage.haskell.org/package/generic-deriving too; I'm sure those compile :-) Pedro 2011/11/3 Magicloud Magiclouds
