[Haskell-cafe] How to fix "undefined reference" error with getDataDir?

[Andy Stewart]

Hi all,

I have two package A and B, and B depend A.

I use below code snippets in package A:

------------------------------> code start <------------------------------
...
import Paths_manatee_ircclient
import System.FilePath
...
  dir <- getDataDir
  let imagePath imageName = dir </> "icons" </> (imageName ++ ".png")
...
------------------------------> code end   <------------------------------

Anyway, package A compile fine, but when i compile package B, i got
below error:

------------------------------> error start <------------------------------
