.NET SFML Binding Not Running, Missing CSFML library

Help
1

For reference, I have not worked with .NET before in any capacity. When trying to run an existing .NET project that uses SFML I get the following error:

> dotnet runUnhandled exception. System.DllNotFoundException: Unable to load shared library ‘csfml-graphics’ or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you’re using glibc, consider setting the LD_DEBUG environment variable:/home/apple/repos/Bathtub/bin/Debug/net10.0/runtimes/linux-x64/native/csfml-graphics.so: cannot open shared object file: No such file or directory/nix/store/cv2ngsd4lxhd7v5whbigfp52y13s0y95-dotnet-sdk-10.0.201/share/dotnet/shared/Microsoft.NETCore.App/10.0.5/csfml-graphics.so: cannot open shared object file: No such file or directory/home/apple/repos/Bathtub/bin/Debug/net10.0/csfml-graphics.so: cannot open shared object file: No such file or directorylibX11.so.6: cannot open shared object file: No such file or directory/nix/store/cv2ngsd4lxhd7v5whbigfp52y13s0y95-dotnet-sdk-10.0.201/share/dotnet/shared/Microsoft.NETCore.App/10.0.5/libcsfml-graphics.so: cannot open shared object file: No such file or directory/home/apple/repos/Bathtub/bin/Debug/net10.0/libcsfml-graphics.so: cannot open shared object file: No such file or directory/home/apple/repos/Bathtub/bin/Debug/net10.0/runtimes/linux-x64/native/csfml-graphics: cannot open shared object file: No such file or directory/nix/store/cv2ngsd4lxhd7v5whbigfp52y13s0y95-dotnet-sdk-10.0.201/share/dotnet/shared/Microsoft.NETCore.App/10.0.5/csfml-graphics: cannot open shared object file: No such file or directory/home/apple/repos/Bathtub/bin/Debug/net10.0/csfml-graphics: cannot open shared object file: No such file or directory/home/apple/repos/Bathtub/bin/Debug/net10.0/runtimes/linux-x64/native/libcsfml-graphics: cannot open shared object file: No such file or directory/nix/store/cv2ngsd4lxhd7v5whbigfp52y13s0y95-dotnet-sdk-10.0.201/share/dotnet/shared/Microsoft.NETCore.App/10.0.5/libcsfml-graphics: cannot open shared object file: No such file or directory/home/apple/repos/Bathtub/bin/Debug/net10.0/libcsfml-graphics: cannot open shared object file: No such file or directory

Here is my shell.nix, which has CSFML installed:

{ pkgs ? import <nixpkgs> { } }:

with pkgs;

mkShell rec {
  nativeBuildInputs = [
    dotnetCorePackages.sdk_10_0-bin
    sfml
  ];

  buildInputs = [
    csfml
    flac
    freetype
    glew
    libjpeg
    libvorbis
    openal
    udev
    xorg.libXi
    xorg.libX11
    xorg.libXcursor
    xorg.libXrandr
    xorg.libXrender
    xorg.xcbutilimage
  ];
}

And here is the .csproj file:

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net10.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="SFML.Net" Version="3.0.0" />
  </ItemGroup>

  <ItemGroup>
  <None Update="FreeMono.ttf">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </None>
</ItemGroup>

</Project>

Any help would be appreciated. It looks like the main issue is that having csfml installed in my shell.nix, isn’t actually exposing it to .NET.

I know nothing about this stack, but just to cover the basics; did you read through https://wiki.nixos.org/wiki/DotNET?

Thanks for nixos wiki link. Unfortunately that didn’t contain a solution. Good news though, I was able to get the dotnet SFML project to run with the following shell.nix

{ pkgs ? import <nixpkgs> { } }:

with pkgs;

mkShell rec {
  nativeBuildInputs = [
    dotnetCorePackages.sdk_10_0-bin
  ];

  buildInputs = [
    sfml
  ];

  shellHook = ''
    export LD_LIBRARY_PATH=${lib.makeLibraryPath buildInputs}:$LD_LIBRARY_PATH
  '';
}
