I think I've seen what might be the same issue. Could you try adding a cc-options: -fPIC like: https://github.com/aavogt/HOpenCV/blob/master/HOpenCV.cabal#L83 ?

Now I get

Loading object (static) dist/build/decnumber/src/decDouble.o ... ghc: panic! (the 'impossible' happened) (GHC version 7.8.2 for x86_64-unknown-linux): Loading temp shared object failed: /tmp/ghc414_0/ghc414_1.so: undefined symbol: BCD2DPD

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

Hi Omari, I had a look at deka. It seems you need to list the decContext.c and decQuad.c in the other order in the cabal file to make the .o files show up in the right order in the call to ghc (you can see it with cabal repl -v). If anything it is odd that ghc-7.6 accepts the objects in the "wrong" order. Regards, Adam
