[Caml-list] fixing swig

[Caml-list] fixing swig

[Joel Reymont]

Here's what happens when building OCaml examples in the latest SWIG:

---
ocamlc -I ` camlp4 -where` -pp "camlp4o pa_extend.cmo q_MLast.cmo" -c swigp4.ml
File "swig.ml", line 159, characters 54-57:
Warning 20: this argument will not be used by the function.
File "swigp4.ml", line 26, characters 2-6:
Parse error: Deprecated syntax, the grammar module is expected
File "swigp4.ml", line 1, characters 0-1:
Error: Preprocessor error
make[1]: *** [ocaml_static_cpp] Error 2
---

The following code from swigp4.ml needs to be fixed but I don't know enough Camlp4 to do it :-(.

If a kind soul can lend me a hand with this then I can try to incorporate the changes back into SWIG.

	Thanks in advance, Joel

I don't have much experience hacking around with camlp4, so this is
partial speculation.

It looks like swig may be using old camlp4 (now camlp5)
libraries/syntax.  As a work-around, you could try dropping in camlp5
in place of camlp4.

Good luck,

Hez

I'd rather fix this to use Camlp4. 

Thanks for the suggestion, though.

The patch attached below almost does it. Example code still fails, e.g. this bit

---
let (xf,yf) = match _factor '((x to int),(y to int)) with
    C_list [ C_int a ; C_int b ] -> a,b
  | _ -> raise BadReturn
---

results in this error

---
File "example_prog.ml", line 19, characters 20-27:
Parse error: "with" expected after [sequence] (in [expr])
File "example_prog.ml", line 1, characters 0-1:
Error: Preprocessor error
---

I'll see if I can figure it out.

Re: [Caml-list] fixing swig

[Joel Reymont]

I was able to update the SWIG OCaml code. Examples mostly work. 

A couple of examples crash but I should be able to fix that.

I will polish things up a bit and submit my patches to the SWIG maintainers.

	Happy New Year!
