Can build Uno targeting windows, linux and wasm when referencing Uno.Toolkit.Skia.WinUI

[KWodarczyk]

Current behavior

Docker image fails to build wit the following errors:

Expected behavior

Docker image should jus build successfully

How to reproduce it (as minimally and precisely as possible)

Create default uno application, add

  <ItemGroup>
      <PackageReference Include="Uno.Toolkit.Skia.WinUI" Version="6.1.8" />
  </ItemGroup>

in .csproj so it should look like this:

<Project Sdk="Uno.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net8.0-windows10.0.19041;net8.0-browserwasm;net8.0-desktop</TargetFrameworks>

    <OutputType>Exe</OutputType>
    <UnoSingleProject>true</UnoSingleProject>

Anything else we need to know?

It works fine when building on windows or linux but fails when building in docker. Perhaps there there needs to be something installed in docker e.g emscripten ?

[kazo0]

@KWodarczyk would you be able to add the /bl switch to your dotnet build command? That way it will generate a .binlog file that will have more information for us to diagnose

https://platform.uno/docs/articles/uno-builds-troubleshooting.html#from-the-command-line

artifacts.zip

Attaching a zip file that contains the .binlog

[jeromelaban]

You need to install python.

When diagnosing these issues, you can open the binlog to get more information.

Note that python install will not be needed anymore when moving to net9.

[KWodarczyk]

@jeromelaban so in order to use Uno.Toolkit we need to have python installed ?

[KWodarczyk]

@jeromelaban

I have added python installation to my docker file:

# Install Python RUN apt-get update && apt-get install -y python3 python3-pip && \ apt-get clean && \ rm -rf /var/lib/apt/lists/*

but now there is different error:

[jeromelaban]

Thanks, make sure to look at all the dependencies that need to be added when building.

The error message tells what's missing (ninja in this case).

[KWodarczyk]

@jeromelaban will look at it but, looks like i needed to install python, now ninja and all this just because i am adding Uno.Toolkit.Skia.WinU to my project, is this expected ? does skia require those things ?
