Re: [Caml-list] Unix module troubles & Time functions

[Julien Michel <julien.michel@etu.univ-orleans.fr>]

Thanks a lot William, I am sure it will the best way for having acces to
the Unix Gettimeofday function.
Nevertheless, I used exactly the same code as you gave me below.

While compiling:
ocamlc -c timer.c
no error !
then compiling:
ocamlc -o timer timer.o timer.ml
I get this error:
"Error while linking timer.cmo:
The external function `my_gettimeofday' is not available"

so I tried:
ocamlc -custom -o timer timer.o timer.ml
no error during compilation
but while executing the generated bytecode, wether it is on the development
plateform, or on the embedded target, I get this error:
Fatal error: unknown C primitive `my_gettimeofday'

I am afraid to have came back to the beggining of my problem, with
unixdup...
I do not understand what is going on.
Everthing seems to be ok from the Ocaml side, but there is something wrong
from Unix/system side.

Is there a way so that the runtime system "ocamlrun" can recognize
"my_gettimeofday"?

Do I have to keep the wole content of the original timer.c file, and only
include my_gettimeofday function?


Cheers
