Hi,

I am using camlidl-1.04 and ocaml-3.04 on Linux.

Following is a section of code generated by camlidl which invokes the 
function camlidl_malloc() declared in caml/camlruntime.h 

value camlidl_test1_write_mark_table(
	value _v_mark,
	value _v_num)
{
  struct marks *mark; /*in*/
  int num; /*in*/
  mlsize_t _c1;
  mlsize_t _c2;
  value _v3;
  struct camlidl_ctx_struct _ctxs = { CAMLIDL_TRANSIENT, NULL };
  camlidl_ctx _ctx = &_ctxs;
  _c1 = Wosize_val(_v_mark);
  mark = camlidl_malloc(_c1 * sizeof(struct marks ), _ctx);
  for (_c2 = 0; _c2 < _c1; _c2++) {
    _v3 = Field(_v_mark, _c2);
    camlidl_ml2c_test1_struct_marks(_v3, &mark[_c2], _ctx);
  }
  num = Int_val(_v_num);
  write_mark_table(mark, num);
  camlidl_free(_ctx);
  return Val_unit;
}

The C file containing this code is compiled into a shared object (.so
file)

But when dynamically linking this C code with Caml code I get the error :

"Error on dynamically loaded library: ./test1_stubs.so: undefined symbol:
camlidl_malloc"

It seems that camlidl_malloc() is declared in camlidlruntime.h but not
defined .

So how do I solve this error ?

Thanx,
Sandeep.
