Hi,

It's been about 5 years since I faced this situation. I'm trying to  
link my program against the Thread module. Things go well until I do  
the ocamlopt compilation, then it aborts the make with the message:

ocamlfind ocamlopt -thread -o sdsp.opt   -package camlp4 -package  
threads -package unix -I ../src -I /usr/local/lib/ocaml/threads  \
	-thread -cclib threads.a  nums.cmxa sdsp.cmxa threads/threads.cmxa   \
	 readline.cmx scmMain.cmx

File "_none_", line 1, characters 0-1:
Error: No implementations provided for the following modules:
          Thread referenced from ../src/sdsp.cmxa(SdlPrims)
make[1]: *** [sdsp.opt] Error 2
make: *** [subdirs] Error 2


Forgive the excessive number of -thread flags in there... this has  
been trial and error.

I understand that it can't seem to find a .ml file to go along with  
the thread.mli, because there isn't one provided by the distribution.  
I also understand that the functionality of the thread module is made  
up largely of the posix threads C-code in the otherlibs directory.  
Somehow the system needs to be coaxed to look into the threads  
subdirectory in the lib/ocaml folder, but I am at wits end at this  
point....

This make is proceeding on Mac OS X 10.4

I'm sure it is possible to do this, because I have an ancient  
(unreadable) make script that does so for another system. Surely  
there is a very simple solution here, short of my inventing an entire  
Makefile script for this project. Eh?

Thanks in advance...
