I have compiled OCaml 3.08 on Mac OS X. I have X11 installed, including
the SDK with the header files and whatnot. When I configured the OCaml
compilation, it did find my X installation and said it would be using
it and installing the graphics module.
But:
$ ocamlmktop -o mytop graphics.cma
$ ./mytop
Objective Caml version 3.08.0
# Graphics.open_graph "";;
Exception: Graphics.Graphic_failure "Cannot open display ".
I get the same exception when I try to put it in a file and compile and
run it, whether compiled with the bytecode compiler or the native code
compiler. So I know this isn't much to go on but I really am not sure
what to do from here to get the Graphics to work so if anyone could
point me in the right direction I would appreciate it.
Thanks.

Does the $DISPLAY environment variable contain the name of the
display?
On my Mac, running in an xterm:
$ echo $DISPLAY
:0.0

Maybe you didn't open X11.app (i.e. launch the X server). Also if you
try to do that from Terminal.app you may need to set the environment
variable $DISPLAY to ":0.0".
By the way you can use dynamic linking, no need to create a new top
level,
> ocaml graphics.cma
Objective Caml version 3.08.0
# Graphics.open_graph "";;
- : unit = ()
Hope that helps,
Daniel

This solved it, thanks. $DISPLAY wasn't set on my machine.
Just out of curiosity, are there any plans for OCaml to use OS X native
graphics stuff rather than X11?

I've make an external implementation of Graphics using Cocoa and Quartz.
It's available here: http://www.pps.jussieu.fr/~henry/ter/

Outstanding, thank you. I was kind of considering implementing this
myself and wasn't really thrilled about the prospect. I don't know
Cocoa at all.
I don't suppose there's any way around the need to create a new thread
is there? Possibly by overriding NSApplication's run method?
