So, I was able to make my link errors go away, by adding `-shared' to my command line: dbanas@dbanas-eeepc:~/prj/haskell/AMIParse/trunk$ make ghc -no-hs-main -shared -dynamic -o ami_test -L. -lami ami_test.o However, when I try to execute the resultant program, I get a segmentation fault: dbanas@dbanas-eeepc:~/prj/haskell/AMIParse/trunk$ ./ami_test test.ami Segmentation fault Tracing this shows that the `main' pointer of the program appears to be NULL: dbanas@dbanas-eeepc:~/prj/haskell/AMIParse/trunk$ gdb --args ./ami_test test.ami GNU gdb (GDB) 7.1-ubuntu Copyright (C) 2010 Free Software Foundation, Inc.
