I have just unsuccessfully tried to load a package which links against
darcs-beta in GHCi. It's a gitit plugin package, and gitit uses the GHC
API, driving GHCi programatically, to load plugins at runtime.
(I first tried linking against darcs 2.2.0, but there is a known issue
with that, so that didn't work.)
I get this error when I try to start gitit and it tries to load the
GHCi runtime linker: fatal error: I found a duplicate definition for
whilst processing object file
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
GHCi cannot safely continue in this situation. Exiting now. Sorry.
How can I figure out what's causing this? Is there some library or
module that's been copied into a separate library on hackage, but still
exists in darcs-beta-188.8.131.52? Or might I be trying to load two versions
of the darcs package? How would I find out?
