Hello,
i'm working with camljava (Xavier Leroy) to call java classes via caml.

It uses jni and c-caml callbacks to achieve this.

A library jni.cma, which permits caml to  achieve this.
In the test package, we have a jnitest.ml, and 2 java classes.

The creation of an executable via ocamlc works fine

ocamlc -I +camljava jni.cma jnitest.ml

launching the executable

CLASSPATH="." ./camlprog works fine.

I'm trying to execute directly the jnitest.ml via the ocaml toplevel.

I've tried doing the following
ocaml -I +camljava jni.cma jnitest.ml but it doesn't work, and i have an
error message that some external functions are not here
The external function `camljava_AllocObject' is not available

If i understand the problem, since these functions are declared as external,
i've tried to build a new toplevel, ocamljni which supports them.
Unfortunately, things don't seem to be that easy.

To achieve jni.cma, we have jni.ml, jni.mli and jnistubs.c

jni.ml is compiled into a jni.cmo
jnistubs.c is compiled into jnistubs.obj

jnistubs.obj is put into library libcamljni.lib

jni.cmo and libcamljni.lib enter in the creation of jni.cma.

I've tried following the same approach, using libcamljni.lib and jni.cmo for
creating the ocamljni toplevel.
when i'm trying to do this
ocamlmktop -verbose -o ocamljni -linkall -custom jni.cmo -cclib -lcamljni
-cclib D:/APPLI/j2sdk1.4.1_01/lib/jvm.lib i'm having the following exception
in the linking process (CL)

+ cl /nologo /MT /Fe"mlfijni.exe" -I"D:\APPLI\MLFi\lib"
c:\TEMP\camlprimcd1cd1.c "libcamljni.lib" "D:/APPLI/j2sdk1.4.1_0
1/lib/jvm.lib" "D:\APPLI\MLFi\lib\libcamlrun.lib" advapi32.lib
camlprimcd1cd1.c
camlprimcd1cd1.obj : error LNK2001: unresolved external symbol
_camljava_CallStaticCamlintMethod
mlfijni.exe : fatal error LNK1120: 1 unresolved externals
Error while building custom runtime system

The function camljava_CallStaticCamlintMethod is defined inside jnistubs.c,
and should be therefore present inside libcamljni.lib.

Am i missing something ??

Thanks in advance for your help.
