[Haskell-cafe] How to generate the .chi file for c2hs?

Hi, I want to make a binding of a gtk function, which returns a X11 type. gtk2hs is made by c2hs, which is OK to give me the .chi file. Well, X11 is not. So if I make my binding c2hs style, I have to make a .chi file for X11 myself. How to do it? -- 竹密岂妨流水过 山高哪阻野云飞
