The type initializer for 'SkiaSharp.SKImageInfo' threw an exception. #26

Alex-451 · 2020-11-24T19:36:36Z

If i build this for linux, i get the error:
The type initializer for 'SkiaSharp.SKImageInfo' threw an exception.
Exception:

 ---> System.DllNotFoundException: Unable to load DLL 'libSkiaSharp' or one of its dependencies: The specified module could not be found. (0x8007007E)

at this line:
 ` var info = new SKImageInfo(660, 660);`

Do you know what causes that and how to fix that?

thank you for the report.
I've confirm that issue when I was installed old SkiaSharp 1.68. What was your package reference?

samples/ManualGenerate and samples/SimpleGenerate can build with both of following package reference.

  <ItemGroup>
    <PackageReference Include="SkiaSharp.QrCode" Version="0.4.0" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="SkiaSharp" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.NativeAssets.Linux" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.QrCode" Version="0.4.0" />
  </ItemGroup>

Alex-451 · 2020-11-25T08:26:08Z

Thanks for the reply, these are my package references:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Discord.Net" Version="2.2.0" />
    <PackageReference Include="Discord.Net.Core" Version="2.2.0" />
    <PackageReference Include="SkiaSharp" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.NativeAssets.Linux" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.QrCode" Version="0.4.0" />
  </ItemGroup>

</Project>```

Unfourtunately it doesnt work.

temporary workaround, add libfontconfig1 package.

apt update
apt install -y libfontconfig1

This is obvious.... I'm digging into more detail.

Hm, https://www.nuget.org/packages/SkiaSharp.NativeAssets.Linux.NoDependencies is one choice.

guitarrapc · 2020-11-25T19:02:45Z

Ok, let's change to SkaiSharp.NativeAssets.Linux.NoDependencies 2.80.2

guitarrapc · 2020-11-25T19:08:48Z

@AlexGipp Can you try with following package?

update: I've released 0.4.1. Please use 0.4.1 and SkiaSharp.NativeAssets.Linux.NoDependencies if you have no dependencies to fonts.

  <ItemGroup>
    <PackageReference Include="SkiaSharp.QrCode" Version="0.4.1" />
    <PackageReference Include="SkiaSharp.NativeAssets.Linux.NoDependencies" Version="2.80.2" />
  </ItemGroup>

In your case,

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Discord.Net" Version="2.2.0" />
    <PackageReference Include="Discord.Net.Core" Version="2.2.0" />
    <PackageReference Include="SkiaSharp" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.NativeAssets.Linux.NoDependencies" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.QrCode" Version="0.4.1" />
  </ItemGroup>

</Project>

Alex-451 · 2020-11-25T21:47:26Z

I still get the same error using the following package references:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Discord.Net" Version="2.2.0" />

    <PackageReference Include="SkiaSharp.NativeAssets.Linux.NoDependencies" Version="2.80.2" />
    <PackageReference Include="SkiaSharp.QrCode" Version="0.4.1" />
  </ItemGroup>

</Project>

guitarrapc · 2020-11-26T01:14:13Z

I can't reproduce issue, can you provide minimum reproduceable sample?

Alex-451 · 2020-11-26T10:22:03Z

I gave you access to the repo (branch: feature/QRCode_generation_rework).
Note: if you want to test the bot make sure to add a discord bot token as well as a prefix in the config.json file (gets created if you run the program for the first time under Resource/config.json)

i use the following command to publish my solution:

dotnet publish -c Release -r linux-x64 --self-contained false

As soon as it hits this part:

info = new SKImageInfo(660, 660);

it crashes with the same error.

guitarrapc · 2020-11-26T10:27:20Z

thank you, I will check it later.

Alex-451 · 2020-11-26T10:29:59Z

Awesome thanks, i will also add a short video later on that shows exactly what i mean.
(NVM cant send a video because github doesnt support that)

Alex-451 · 2020-11-29T20:28:16Z

@guitarrapc did you firgure anything out / did you manage to reproduce the issue?

guitarrapc · 2020-11-30T03:53:43Z

@AlexGipp Sorry I was down for these days, Let me check tonight.

guitarrapc · 2020-12-01T17:13:17Z

@AlexGipp Hi, I've tried your repo with this lib's branch.
It seems no trouble with running on WSL2 Ubuntu 20.04 LTS.

# on bash on Ubuntu 20.04 LTS
$ dotnet publish -c Release -r linux-x64 --self-contained false
$ cd ./bin/Release/netcoreapp3.1/linux-x64
$ dotnet YOUR_APP_NAME.dll

I've pushed test code branch to your origin for your reference.
Also I've added docker support, and docker seems no troble with Qr generation.

Let's cralify detail.

What is your Linux environment?
- Is it docker, or any? If so It can be reprodusable.
If your env can use apt, yum and similar package management, then apt install libfontconfig1 and replace SkiaSharp.NativeAssets.Linux.NoDependencies to SkiaSharp.NativeAssets.Linux package is alternate way.

Alex-451 · 2020-12-01T18:05:33Z

Thanks for getting back to me @guitarrapc, my linux environment is: Debian 10 x64 (buster)
I will look into the solution you have provided :)

guitarrapc · 2020-12-01T18:19:13Z

A Dockerfile I've pushed to your repo was FROM mcr.microsoft.com/dotnet/core/runtime:3.1-buster-slim AS base, Debian 10 env and it runs successfully.

Alex-451 · 2020-12-02T09:26:28Z

@guitarrapc So how did you actually solve the issue?
(Note that i have never used docker and have no idea how it works)

guitarrapc · 2020-12-02T11:17:20Z

@AlexGipp I did nothing to docker image, it means default 3.1-buster-slim image doens't trouble any.

image seems setup with https://github.com/dotnet/dotnet-docker/blob/801573a24f0c45fabb0db24ff8d3425c1957e068/src/runtime/3.1/buster-slim/amd64/Dockerfile and https://github.com/dotnet/dotnet-docker/blob/c0e8be8a44b47b1dcc2a5b4b2ebd92022087ac0b/src/runtime-deps/3.1/buster-slim/amd64/Dockerfile based on buster's scratch image https://github.com/debuerreotype/docker-debian-artifacts/blob/794e462d2825fb1ebb3d54ff5c93dd401cf28b9a/buster/slim/Dockerfile.

runtime:3.1-buster-slim has installed packages for dotnet runtime, but it should be same to your env, right?.

        ca-certificates \
        \
        # .NET Core dependencies
        libc6 \
        libgcc1 \
        libgssapi-krb5-2 \
        libicu63 \
        libssl1.1 \
        libstdc++6 \
        zlib1g \

Situation indicate trouble is something due to your environment specific and I need reproduceable step to determine root cause.
