ocamlbuild and the "status bar"

[Joel Reymont]

Folks,

I'm trying to set up my first OCaml project and I just read through  
the ocamlbuild presentation [1]. I really like this tool but I can't  
figure out where to get the nifty "status bar" functionality  
described towards the end of the slides.

Any clues?

	Thanks, Joel

This is a rather silly question so I retract it. A much better  
question is the following...

How do I integrate ocamlbuild with external libraries?

I have OUnit installed in /usr/local/lib/ocaml/site-lib/ounit since  
it uses ocamlfind during installation. I have to use a longish  
command line to make OUnit examples compile, like this:

ocamlbuild -cflags -I,/usr/local/lib/ocaml/site-lib/ounit -lflags -I,/ 
usr/local/lib/ocaml/site-lib/ounit -libs unix,ounit test_list.byte

Maybe the solution here is to build OUnit with ocamlbuild but I  
haven't figured how to do this yet. Investigating!

	Thanks, Joel

It's by default on the standard version.

It can be disabled with the -classic-output command line flag.
It's disabled in the ocamlbuildlight version that is used in OCaml for
bootstrapping.

There is many solutions and you get one of them.

1/ Comand line solutions

1.1/ Using ocamlfind:

Since it's an ocamlfind package you can use it.

ocamlbuild -ocamlc "ocamlfind ocamlc -package ounit" -lfags -linkpkg
-lib unix test_list.byte

1.2/ Using the library directly (like you did).

2/ Shell script/Makefile solution

Put all your stuffs form the previous solutions in a shell script or a Makefile.

3/ A solution with an Ocamlbuild plugin:

$ cat _tags
"test_list.byte": use_unix

$ cat myocamlbuild.ml
open Ocamlbuild_plugin;;
open Command;;

let packages = "ounit" (* "pkg1,pkg2,..." *);;

let ocamlfind cmd =
  S[A"ocamlfind"; A cmd; A"-package"; A packages];;

flag ["ocaml"; "link"] (A"-linkpkg");;

dispatch begin function
  | After_options ->
      Options.ocamlc := ocamlfind "ocamlc";
      Options.ocamlopt := ocamlfind "ocamlopt";
  | _ -> ()
end

$ ocamlbuild test_list.byte
Finished, 3 targets (2 cached) in 00:00:00.
