I'm trying to compile with the native windows port (3.06), and bytecode =
compiling seems fine, but both linking bytecode and native compiling =
ocamlopt give the same error:

ocamlopt -c -thread -I +lablgtk -I /cygdrive/d/Frank/lib rnd.ml
Fatal error: exception Invalid_argument("Filename.temp_file: temp dir nonexistent or full")
make: *** [rnd.cmx] Error 2

The code compiles and runs fine under Linux.

This is on Windows XP, and I just did the standard install plus lablgtk, =
as in the instructions. Any clue how to remedy this ?

The error message should be more detailed, but what it says is that
OCaml cannot find a directory to put its temporary files. This
temporary directory is the value of the TEMP environment variable, if
set, or C:\temp otherwise. Apparently, recent versions of Windows
neither create C:\temp nor set the TEMP variable. Just create a
directory named "temp" in drive C and you should be all set.

XL, 2003/03/24: use current dir as temp dir under windows, unless TMPDIR is set.
