This tests the support for the bigarray atom in the dune libraries stanza.
|
|
|
|
History:
|
|
- OCaml 4.08 ([ocaml/ocaml#2263](https://github.com/ocaml/ocaml/pull/2263))
|
|
deletes the `map_file` functions completely, requiring _all_ code to be
|
|
updated to use `Unix.map_file`, if appropriate. From this release, it is
|
|
unnecessary to link with the separate Bigarray library.
|
|
- OCaml 5.00 ([ocaml/ocaml#10896](https://github.com/ocaml/ocaml/pull/10896)
|
|
removes the separate Bigarray library.
|
|
|
|
Code may be written which is designed to support both OCaml 4.06 and earlier and
|
|
also OCaml 5.0+. In such cases, it is appropriate to have `(libraries bigarray)`
|
|
even though there is no Bigarray library in OCaml 5.
|
|
|
|
This test uses `(libraries bigarray)` (the program uses `Bigarray`)
|
|
$ dune exec a/a.exe
|
|
Welcome to a
|
|
This test uses `(libraries (re_export bigarray))` similarly
|
|
$ dune exec b/b.exe
|
|
Welcome to b
|
|
This test uses a `(select )` construct and should always select bigarray support
|
|
$ dune exec c/c.exe
|
|
Welcome to c WITH bigarray support
|
|
This test uses a `(select )` construct and should always select bigarray
|
|
support (the evaluation of `select` order differs from the previous test)
|
|
$ dune exec d/d.exe
|
|
Welcome to d WITH bigarray support
