[Caml-list] OASIS help

[Laurent Thévenoux]

Hello,

I’m trying to use OASIS to configure a project written in OCaml. I currently use a Makefile which works fine but doesn’t allow enough possibilities. My project uses the menhir parser but OASIS attempts to use ocamlyacc. 

How can I specify that I need to run ocamlbuild with -use-menhir instead of ocamlyacc ?

Regards,
Laurent Thévenoux

Put a BUILFLAGS line as the first line of your Makefile:

---
BUILDFLAGS = " -use-menhir "
# OASIS_START
[...]
---

This part of the Makefile will be kept by oasis.

OASIS doesn’t generate me a Makefile. Here my _oasis file (a very basic start):

—
OASISFormat: 0.4
Name:        name
Version:     0.1
Synopsis:    synopsis
Authors:     Laurent
License:     CeCILL

Executable exe
  Path:       src
  BuildTools: ocamlbuild
  BuildDepends: str
  MainIs:     main.ml
—

Then, I run oasis setup, and, ocaml setup.ml -configure, and finally, ocaml setup.ml -build.

It fails during the build because ocamlyacc is called to build a menhir parser.

Did I miss anything?

Sorry, I forgot: add this line after your License line in your _oasis file:
Plugins: DevFiles (0.4)

Alternatively, you could edit _tags file the following after calling oasis
setup.

# OASIS_START
# DO NOT EDIT (digest: d41d8cd98f00b204e9800998ecf8427e)
# OASIS_STOP
*true : use_menhir, explain*

[Caml-list] oasis help

[Jiten Pathy]

I have two modules defining the same function.
How would i conditionally open modules during compilation using oasis
/ocamlbuild?(i.e pass -open A or -open B depending on some flag from
oasis?)

You can access the oasis environment from myocamlbuild.ml and setup
compilation flags according to it. See for instance:

  https://github.com/janestreet/bin_prot/blob/master/myocamlbuild.ml

So you could have this in your _oasis:

  Flag use_b
  Default: false

And in your myocamlbuild.ml:

----------------------------------
(* OASIS_START *)
(* OASIS_STOP *)

let dispatch = function
  | After_rules ->
    let env = BaseEnvLight.load () in
    let module_name = if BaseEnvLight.var_get "use_b" = "true" then "B"
else "A" in
    flag ["ocaml"; "compile"] (S ["-open"; module_name])
  | _ ->
    ()

let () = Ocamlbuild_plugin.dispatch (fun hook -> dispatch hook;
dispatch_default hook)
----------------------------------

Re: [Caml-list] oasis help

[Jiten Pathy]

Thanks. ocamlbuild seems to have a nice plugin api.

I ended up using
tag_file "target.ml" [Printf.sprintf "open(%s)" module_name]

[Caml-list] OASIS help

[Robert Soulé]

[-- Attachment #1: Type: text/plain, Size: 1045 bytes --]

Hello,

I am trying to create an _oasis file with a Test section. My test will
call an executable that is built in an Executable section. The test
executable links agains links against my project library, which uses
some c code. My oasis file is attached.

When I run "oasis setup" and then "make", everything works fine. I see
Test.native in my directory, as I would expect.

However, I run into problems when I run "make test":

$ ocaml setup.ml -test
W: Tests are turned off, consider enabling with 'ocaml setup.ml
-configure --enable-tests'

$ ocaml setup.ml -configure --enable-tests
ocamlfind: Package `with-c' not found
W: Field 'pkg_with_c' is not set: Command
''/Users/soule/.opam/4.00.1/bin/ocamlfind' query -format %d with-c >
'/var/folders/q1/hc432vx951b6dlfrvybzm4d40000gn/T/oasis-c91777.txt''
terminated with error code 2
E: Cannot find findlib package with-c
E: Failure("1 configuration error")

Is there an extra Field I need to add in the Test section if I am
running an executable that links against C code?

thank you,
Robert

The _oasis file you send is partial, I see no definition of with-c or
mylibwithc. As far as I read, I think the part you send us is fine.
(well you may not set Run: true).

Can you send us a more complete _oasis ?
