Interesting. I was unable to reproduce your problem. What platform
are you running on? Are you using a binary distribution or one you
built from source?
Seems like something didn't build right... You might use 'nm' to
examine your libHSCabal.a to see if a similarly named symbol is
present. For example, is there a leading underscore? May the
version ("m1zi1zi6") isn't present?

Dear GHC hackers,
I would like to experiment with the GHC API. However I get link
errors when
using it. For example:

I also get this when compiling for example the following module
testGHC.hs:

module Main where
import qualified GHC
import DynFlags (defaultDynFlags)
main = GHC.defaultErrorHandler defaultDynFlags $ putStrLn "Hello
World"

I would like to know what is causing this and how I can fix it?
Also, should I
file a bugreport?
Greetings,
