Bulat,
Some very good suggestions. I will try to appease Ceiling Cat and
reduce my (perhaps gratuitous) use of unsafePerformIO. I'm going to
have to use it somewhere, since I want referentially transparent code
(and I try to avoid the IO monad when possible, anyway).

Malcolm,
I saw this suggestion somewhere else. Unfortunately, it didn't help either.
I still get the undefined reference errors. I did eventually get ghc to
compile
Main.hs by putting the -c and -cpp flags after --make Main.hs.
Then it produces a Main.o file which (even with +x permissions on
Sorry. In my haste to paste in the .c file, I left out all the include
statements. I do have #include srilm.h there (which to my non-
C/C++ mind seems stupid -- why the hell would you need to import
the header file for the code that it's a header *for*?)
Still no dice.
Thanks for your time,

Anyhow, still no dice. Even when cleaning up my Haskell code, I can't get

Which is weird, because 'srilm.o'/'srilm.h' are the files that define the
mysterious undefined references. I'll keep plugging away and report
back when (or whether) I make some progress. In the meanwhile, if anyone
has a clue, I'm all ears.
Best,

Nope. Ubuntu Linux (Intrepid Ibex). I wish it were that simple.

Hi all,
I got it to work...finally. Basically, I used Malcolm's suggestion of
tracking down all the
SRILM .o files needed. I need to run now, but I'll post the gory (oh, so
gory) details soon.
Thanks to all who helped.
Best,

I'm using typeclasses to implement a sort of common interface for all

implement a set of functions -- an 'interface' in OOP-speak. (Yes,
