PrimopWrappers.dyn_o has a direct reference to newSpark but since it resides in the rts, not ghc-prim, such references must be redirected through PLT. The problem is that every *.dyn_o, not only PrimopWrappers.dyn_o, is compiled without -fPIC for OSes other than Windows, Darwin and Linux. I have no idea why -fPIC isn't enabled for all OSes in the first place, but the attached patch works at least for me. }}} [http://www.haskell.org/pipermail/ghc-devs/2013-March/000748.html From: Kazu Yamamoto] {{{ Thanks.
