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 <------------------------------ Linking dist/build/manatee/manatee ... /home/andy/.cabal/lib/manatee-ircclient-0.0.1/ghc-6.12.3/libHSmanatee-ircclient-0.0.1.a(Smile.o): In function `s6sP_info': (.text+0x3bea): undefined reference to `manateezmircclientzm0zi0zi1_Pathszumanateezuircclient_getDataDir3_closure'
Often these linker problems arise if A was altered and recompiled and not all depending parts of B were recompiled. However, 'cabal install' which in turn calls 'ghc --make' should automatically find and compile the affected modules of B. Maybe it fails in trying to do so. I would try to remove dist/build of packages A and B and then compile and install the packages again.
