This isn't Haskell syntax. Atleast not directly. It is either hsc2hs[1] or c2hs [2]. Also see [3] for the difference between the two. Soin order to compile that code you first have to run it through aspecial preprocessor. 1 - http://www.haskell.org/ghc/docs/7.2.1/html/users_guide/hsc2hs.html2 - http://www.cse.unsw.edu.au/~chak/haskell/c2hs/3 - http://stackoverflow.com/questions/6009031/difference-between-hsc2hs-and-c2h... 2011/10/3 Magicloud Magiclouds :

Hi,  I am learning to use data-flags, and got this example code: import Data.Flags newtype MyFlags = MyFlags CInt deriving (Eq, Flags) #{enum MyFlags, MyFlags  , myFlag1 = C_FLAG1  , myFlag2 = C_FLAG2  , myFlag3 = C_FLAG3  }

 I modified it trying to compile it. Well, I got illegal syntax at "#{e".  In fact, I am not quite know the syntax here. Any clue?

I see. I was mislead, did not noticed the c binding part. Thank you. -- 竹密岂妨流水过 山高哪阻野云飞
