Thanks for the investigation. I thought `-fPIC` is required in some cases, or for some architectures? But I must admint that I’m still mostly ignorant about linker issues.
That's true! After reading about linking a bit more: You need `-fPIC` on x86_64 when building shared libraries. And all static libaries that the shared library links against must also be built with `-fPIC`. I guess the "solution" I posted is more a non-portable hack. I'm not well versed in linking either. Hopefully it will atleast give some clues to the problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9657#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
