Test that we support the use case of using additional constraints to force the
|
||
|
|
system compiler to be used instead of installing the compiler.

Create packages resembling the ocaml compiler packages
|
||
|
|
$ mkrepo
|
||
|
|
|
||
|
|
$ mkpkg ocaml-base-compiler <<EOF
|
||
|
|
> conflicts: [ "ocaml-system" "ocaml-variants" ]
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
$ mkpkg ocaml-variants <<EOF
|
||
|
|
> conflicts: [ "ocaml-system" "ocaml-base-compiler" ]
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
$ mkpkg ocaml-system <<EOF
|
||
|
|
> conflicts: [ "ocaml-variants" "ocaml-base-compiler" ]
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
$ mkpkg ocaml <<EOF
|
||
|
|
> depends: [
|
||
|
|
> "ocaml-base-compiler" | "ocaml-variants" | "ocaml-system"
|
||
|
|

|

A package that depends on ocaml:
|
||
|
|
$ cat > dune-project <<EOF
|
||
|
|
> (lang dune 3.13)
|
||
|
|
> (package
|
||
|
|
> (name foo)
|
||
|
|
> (depends ocaml))
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
Try solving without additional constraints:
|
||
|
|
$ add_mock_repo_if_needed
|
||
|
|
$ dune pkg lock
|
||
|
|
Solution for dune.lock:
|
||
|
|
- ocaml.0.0.1
|
||
|
|
- ocaml-base-compiler.0.0.1
|
||
|
|
|
||
|
|
Now make a workspace file adding the constarint on ocaml-system:
|
||
|
|
$ cat >dune-workspace <<EOF
|
||
|
|
> (lang dune 3.13)
|
||
|
|
> (lock_dir
|
||
|
|
> (constraints ocaml-system)
|
||
|
|
> (repositories mock))
|
||
|
|
> (repository
|
||
|
|
> (name mock)
|
||
|
|
> (url "file://$(pwd)/mock-opam-repository"))
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
Solve again. This time ocaml-system is chosen.
|
||
|
|
$ dune pkg lock
|
||
|
|
Solution for dune.lock:
|
||
|
|
- ocaml.0.0.1
|
||
|
|
- ocaml-system.0.0.1
