Ocaml community,
For fun I wrote a version of Life for ocaml +labltk.

http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life

Here are the 3 ways I've tried to run it and the results:

1. compile to bytecode or native:
"Fatal error: exception Protocol.TkError("Tcl/Tk not initialised")"

2. #load all the libraries into the toplevel (or give them as command 
line arguments) then #use "lifemain.ml":
works

3. Run the toplevel with "lifemain.ml" as an argument:
gives an empty Tk window

The results are the same on Mac OS X and Windows XP (mingw).

Here's the toplevel command:
ocaml -I +labltk -I +threads unix.cma labltk.cma threads.cma 
tkthread.cmo life.cma lifeui.cma lifemain.ml

or leave off "lifemain.ml" and do a #use "lifemain.ml".

to compile:

ocamlc -I +labltk -I +threads -o life unix.cma labltk.cma threads.cma 
tkthread.cmo life.cma lifeui.cma lifemain.ml

The sources are at

http://www.msu.edu/~shawjef3/life/life.ml
http://www.msu.edu/~shawjef3/life/lifeui.ml
http://www.msu.edu/~shawjef3/life/lifemain.ml

Any ideas about how to get a bytecode or native compiled version working?

Thanks,
Jeff
