Solution for dune.lock:
|

By default, local packages have version `dev` so the following version
|
||
|
|
constraint on `foo` will fail:
|
||
|
|
|
||
|
|
$ solve_project <<EOF
|
||
|
|
> (lang dune 3.11)
|
||
|
|

|

Error: Unable to solve dependencies for the following lock directories:

Lock directory dune.lock:

Couldn't solve the package dependency formula.

- foo -> (problem)

No usable implementations:
|

|
foo.1.0.0: Package does not satisfy constraints of local package x
|
||
|
|
[1]
|
||
|
|
|
||
|
|
But specifying a version for the local package `x` yields a solution:
|
||
|
|
|
||
|
|
$ solve_project <<EOF
|
||
|
|
> (lang dune 3.11)
|
||
|

|
||
|
|
> (version 1.0.0)
|
||
|
|
> (package
|
||

> (name x)
|

|

Solution for dune.lock:
|
||
|
|
- bar.1.0.0
|
||
|
|
- foo.1.0.0
|
||
|
|
|
||
|
|
Same result if the version of package `x` is specified by the opam file instead
|
||
|
|
of the dune-project:
|
||
|
|
|
||
|
|
$ dune build x.opam
|
||
|
|
$ grep '^version' x.opam
|
||
|
|
version: "1.0.0"
