L.S.,

I am trying to run a program in GHCi, but I get a meesage that an object file is loaded twice; it appears that two different versions of package "process" are loaded, see the session text below. How can I solve this?


GHCi, version 6.10.1: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.

GHCi runtime linker: fatal error: I found a duplicate definition for symbol
   _runInteractiveProcess
whilst processing object file
   C:\Programs\ghc\ghc-6.10.1\process-1.0.1.0\HSprocess-1.0.1.0.o
This could be caused by:
   * Loading two different object files which export the same symbol
   * Specifying the same object file twice on the GHCi command line
   * An incorrect `package.conf' entry, causing some object to be
     loaded twice.
GHCi cannot safely continue in this situation.  Exiting now.  Sorry.
