PathMap not supported by F#?

[njlr]

Repro steps

I want to have deterministic builds, regardless of the folder that the project is checked-out into.

Following information found here, I added a PathMap property to my fsproj:

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <Deterministic>true</Deterministic>
    <DeterministicSourcePaths>true</DeterministicSourcePaths>
    <PathMap>$(EnlistmentRoot)=/home/runner/</PathMap>
  </PropertyGroup>

Expected behavior

Deterministic builds

Actual behavior

$ dotnet build
usr/share/dotnet/sdk/5.0.103/FSharp/Microsoft.FSharp.Targets(281,9): error MSB6006: "dotnet" exited with code 134.

Known workarounds

This is a C# compiler flag. Adding support for this is ongoing, see dotnet/sourcelink#601

I implemented support for this in the compiler in #9874, so we should be good to go.

@baronfel Thanks for responding! I am finding documentation a little sparse. Suppose I have many .fsproj files that are part of a single .sln. What is the best way to enable deterministic paths for all projects?

[baronfel]

What about setting the Deterministic property to true in a Directory.Build.props file?

[njlr]

I have already set these properties in my .fsproj files:

    <Deterministic>true</Deterministic>
    <DeterministicSourcePaths>true</DeterministicSourcePaths>

However, if I cat the output .dll I can see the absolute paths to the source files in there.

It needs a <SourceRoot Include="path"> to actually strip away everything until the root of the project, Source Link simplifies this by figuring out the SourceRoot based on your vcs info. https://github.com/dotnet/sourcelink

Sorry, I am not familiar with all of this stuff. What would path be in this case?
