While experimenting with Haskell using the Stack Tool to build a gtk+ gui by enhancing the Main.hs code from the new-template as follows:

module Lib

    ( someFunc

    ) where



import Control.Monad

import Control.Monad.IO.Class

import Data.IORef

import Graphics.UI.Gtk hiding (Action, backspace)



someFunc :: IO ()

someFunc = do

    void initGUI

    window <- windowNew



    widgetShowAll window

    mainGUI

I am encountering the following weird error in which the target seems to be searching for a later version of itself:

>stack build



glib-0.13.6.0: configure

cairo-0.13.5.0: configure

Progress 2/6

    Configuring cairo-0.13.5.0...

    setup: The pkg-config package 'cairo' version >=1.2.0 is required but it could

    not be found.

Thanks in advance for any assistance.

cairo-0.13.5.0 seems to be the haskell bindings to the cairo C library (just a guess). The cairo C library's current version is 1.16 and it is "beyond 1.0" for years already. So yes, indeed, cairo requires cairo. But this is "haskell cairo bindings requires cairo C library".
