It should be mentioned that most of the OOHaskell functionality (extensible polymorphic records and variants) are actually in HList. Einar Karttunen has ported the latter to GHC 6.6 and package under Cabal. I think the version is available on Hackage. Anyway, the curious behavior requiring the presence of OOHaskell sources seems like a problem with GHC separate compilation. Could that be distilled to a small example so that we can file a GHC problem report?
The smallest example I was able to construct involved building HList and OOHaskell and installing them as modules. This was trivial in some sense, but I think it did require some modification (maybe the creation of a cabal file?). After that I simply tried to compile the examples provided using the libraries I had built. For some reason when I did this, the type checker rejected the examples. Building all the code together, as it's packaged worked fine. I have not tried recently. thanks, Jason _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
