error FABLE: Cannot reference entity from .dll reference: Chia.Shared.Ids.SortableRowKey

[tforkmann]

Description

Chias shared model doesn't get fully compiled.
I get following error message:

error FABLE: Cannot reference entity from .dll reference: Chia.Shared.Ids.SortableRowKey

Repro code

The module inside Chia looks like this:

module Ids =
        type ReportId =
            | ReportId of reportId: int
            member this.GetValue = (fun (ReportId id) -> id) this
            member this.GetValueAsString = (fun (ReportId id) -> string id) this


        type SortableRowKey =
            | SortableRowKey of string
            member this.GetValue = (fun (SortableRowKey id) -> id) this

        module SortableRowKey =
            let toRowKey (dateTime: DateTime) =
                String.Format("{0:D19}", DateTime.MaxValue.Ticks - dateTime.Ticks) |> SortableRowKey
            let toDate (SortableRowKey ticks) = DateTime(DateTime.MaxValue.Ticks - int64 ticks)

Is there any way to get this working?

Expected and actual results

Module should get compile

@tforkmann Is Chia compiled as a shared library or referenced as a project? If it is a library where you don't have access to the source code, then you can make it Fable-compatible by publishing the sources as well like all Fable packages do

[alfonsogarciacaro]

Yes, as @Zaid-Ajaj says, you need to include the F# sources in the package for Fable to be able to compile and access the code as in here: https://github.com/Fulma/Fulma/blob/0e7330d95f7555710dde1f0f992732b9bb357a43/src/Fulma/Fulma.fsproj#L68-L71

Maybe we should improve the error message 🤔

[tforkmann]

Thanks guys! That worked!

@Zaid-Ajaj I'm getting the same error when using ProjectReference with a plugin defined in the same project. Is it possible to get that to work, or does it have to be published separately?

[tforkmann]

@joprice If possible get rid of Chia since the maintainer of that project arent working at that company anymore.

[joprice]

Thank you, but I'm not using Chia. This is for a separate compiler plugin I've written locally.

[tforkmann]

ahh ok

[joprice]

I just noticed that the errors are actually for transitive dependencies. Not sure if that helps clarify the error:

error FABLE: Cannot reference entity from .dll reference, Fable packages must include F# sources: Fable.MemberDeclarationPluginAttribute
error FABLE: Cannot find Fable.AST.Fable.Ident constructor
error FABLE: Cannot find Fable.AST.Fable.Expr constructor
error FABLE: Cannot find Fable.AST.Fable.ImportInfo constructor
error FABLE: Cannot find Fable.AST.Fable.MemberDecl constructor

[joprice]

Ah this was the issue: #3625 (comment). Need to exclude it from compilation to avoid generating js for the plugin code.
