Failed link to mixed-language shared object.
Hi all, Does this trigger recollection in anyone: dbanas@dbanas-eeepc:~/prj/haskell/AMIParse/trunk$ make ghc -dynamic -o ami_test -L. -lami ami_test.o ./libami.so: undefined reference to `__stginit_haskell98_MarshalArray_' ./libami.so: undefined reference to `__stginit_haskell98_MarshalError_' collect2: ld returned 1 exit status make: *** [ami_test] Error 1 dbanas@dbanas-eeepc:~/prj/haskell/AMIParse/trunk$ ? Know what I need to do? Thanks, -db

First thing to try is always --make; GHC's default behavior is, shall we say, not optimal otherwise. (I consider it highly broken; somewhere in there the default is *supposedly* going to change to --make, I believe.) If you want to try to make it work the ugly old way, the symbol names suggest to me that "-package haskell98" would help. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms

? Know what I need to do?
Thanks, -db
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
