RE: [Caml-list] problem while linking

[EL CHAAR RABIH]

Dear abdellah,
i have already faced this problem and found a way to make things work.
You are having conflicts with the names you are passing.

The creation of object-files from the native compiler is rather tricky.
My understanding is the following :
if you compile a.ml with ocamlopt, two compilation phase are executed (in
windows at least) converting assembly code .asm into .obj
you therefore have a.obj and a temporary file temp.obj
These two files are put together using lib (along with stdlib.lib) in order
to create a.obj ??
My understanding is that the conflict comes here. If you specify a name for
the output-obj different then a.obj, then you will have no conflict.

ocamlopt -output-obj -o test.obj exemple_ml.ml

test.obj won't conflict with the existing exemple_ml.obj

At linking, the command becomes

LINK /LIBPATH:"C:\Program Files\Objective Caml\lib" /OUT:exec.exe
libasmrun.lib exemple_c.obj test.obj


Sincerely yours.
Rabih

PS: i suspect that the original link command refers to exemple_c.obj
exemple_ml.obj and not twice exemple_ml.obj

Objet : [Caml-list] problem while linking


hello,
I'm trying to add some ocaml code to an existing C application and I'm
having problems linking the whole thing on Windows.
Here's are the commands that I use to build the whole thing: 
cl /c exemple_c.c
ocamlopt -output-obj exemple_ml.ml
LINK /LIBPATH:"C:\Program Files\Objective Caml\lib" /OUT:exec.exe
libasmrun.lib exemple_ml.obj exemple_ml.obj
And here are the link errors that result from the last command: 
exemple_ml.obj : error LNK2001: unresolved external symbol _caml_curry2
libasmrun.lib(fail.obj) : error LNK2001: unresolved external symbol

Re: [Caml-list] problem while linking

[Nathaniel Gray]

I'm pretty sure this is a case where you've built part of your program
with ocaml 3.08 but you're linking against libraries from ocaml 3.07. 
Some functions were renamed in between these versions.  Try rebuilding
your entire project, and make sure you don't have any old libraries
from 3.07 lying around.
