Is it possible to build Prelude from scratch. Or just some modules like GHC.Base. For example when I do % ghcjs-inplace.bat -fglasgow-exts -fjavascript -cpp -c Err.lhs-boot % ghcjs-inplace.bat -fglasgow-exts -fjavascript -cpp -c Base.lhs I've got this error: Base.lhs:94:0: Bad interface file: C:/Program Files/Visual Haskell\imports/GHC/Err.hi-boot Something is amiss; requested module base:GHC.Err differs from name found in the interface file main:GHC.Err What can I do to overcome this. Really what I want is to build some runtime system for my ghc-derived-javascript-compiler. And to embed JavaScript integers into it. I understand that I need to write some primitive operations in JavaScript like addition. I can build some numerals on the top of Haskell, but I'd like to get access to underlying javascript features and integers is a good point to start. Can you recommend me some strategy or smth? -- vir http://vir.comtv.ru/
