Link errors with O'Caml 3.09 and Camlidl 1.05

Link errors with O'Caml 3.09 and Camlidl 1.05

[Kathleen Fisher]

We installed O'Caml 3.09 on MacOS 10.4 from the .dmg image, then  
installed
Camlidl with no errors.  When we link our Camlidl test program,
we get the link errors below.  However, when we install OCaml 3.09
from source, compile it, and install Camlidl, we do not get
any link errors.

Can someone explain this behavior?

Thanks!
Kathleen Fisher

Try to add the following options : -cclib -lSystemStub

Hi Damien,
Thanks for your quick response.  I have another linking
problem on the Mac O/S 10.4 with O'Caml 3.09.  I'm getting
undefined _caml* symbols (see below).  From the link step,
you can see that I'm using a lot of libraries
(pcre, netstring, pxp, camomile, etc).
Any ideas?
Thanks, Mary

I suspect that one of the libraries uses the -pack option (probably 
camomile). Unfortunately, this option does not work well under OCaml 
3.09 (with ocamlopt). You can try to apply to OCaml the patch from here:

Hi Alain,

We reported a bug in November with 3.09 when 
using ocamlopt to compile libraries build with the -pack option.
You said it was fixed by this patch:
http://caml.inria.fr/mantis/view.php?id=3825

Is this patch installed in the current release 3.09.1?
>From the dates in the patch log, it looks like it should be,
but I can't find any doc to be sure, and we are still
getting link errors.

Also, is this patch installed in the binary releases for Linux & MacOS?
It looks like the binary releases for Windows are still 3.09.0.

We want to be sure the patch is installed in all the downloadable
compilers as we can't ask our users to do patches by hand.

Thanks a lot!
Mary

Yes.

Do you get the same errors or different ones?

Another issue with -pack could explain link errors:
http://caml.inria.fr/mantis/view.php?id=3827

When you pack units together with ocamlopt, you must ensure that the 
compiler sees the .cmi files (you must give -I options). This was not 
the case before OCaml 3.09.

I can indeed reproduce link errors with a trivial program using 
Camomile. I guess Camomile's Makefile has to be fixed.

Hello again,

Actually, the patch to Camomile's Makefile is trivial. You can simply 
add $(INCLUDES) to line 137:

$(OCAMLOPT) -pack -o camomile.cmx camomileconfig.cmx $(OPTOBJECTS)

(and also to line 134 for cosmetic reasons)

One could argue that OCaml should issue a proper error message when the 
.cmi files are not available.


I put Camomile's developper in Cc: of this mail.

Thanks, Alain.  I will prepare another release in this weekend.

Thanks, Alain, for the explanation and fix.
