Yes! It seems the details from my first mail (10/15/12 3:25 PM) fell out. Here is the relevant parts from that mail: " The problem I have is that I get a linker error when compiling a shared library with GHC. This problem occurred after I updated GHC from 7.0.3 to 7.4.1. Here is the error itself: /usr/bin/ld: ../src/Shared.so relocation R_X86_64_32S against `ghczmprim_GHCziTypes_ZC_con_info` can not be used when making a shared object; recompile with -fPIC ../src/Shared.so: could not read symbols: Bad value collect2: error: ld returned 1 exit status Here is the ghc command: ghc -O2 --make -no-hs-main -optl '-shared' -optc '-DMODULE=Shared' - -o ../bin/pet_assembler_core.so Shared ../src/shared/module_init.c - -i../src/; Information about the system: Linux 2.6.32-5-amd64 Debian 6.0.6 GHC 7.4.1 GCC 4.7.2 GNU ld 2.22 " I tried adding -fPIC and -dynamic to the ghc command: ghc -O2 --make -no-hs-main -optl '-shared' -optc '-DMODULE=Shared' - -o ../bin/pet_assembler_core.so Shared ../src/shared/module_init.c - -i../src/ -fPIC -dynamic; And got this error: ../src/Shared.hs:1:1: Could not find module `Prelude` Perhaps you haven't installed the "dyn" libraries for package `base'? Locations searched: Prelude.hs Prelude.lhs ../src/Prelude.hs ../src/Prelude.lhs /usr/lib/ghc/base-4.5.0.0/Prelude.dyn_hi Does that mean I can just install those libraries or do have to compile ghc from source and pass some flags to include those librares?
