Ceres (MCTS Chess Engine) not installing

Hello all,
I am a hobby chess player who recently switched to Arch. I have been trying to install the following chess engine - https://github.com/dje-dev/Ceres. It is an MCTS engine that requires the Dot net framework.

I installed the dotnet sdk using yay -S dotnet-sdk. There were no errors for the same.

Next I tried installing the engine itself. I cloned the github repo, went to Ceres/src/Ceres and provided the command : dotnet run --configuration Release

According to the author of the engine, this was supposed to work. However, I got the following errors and the executable wasn't built:

/home/divine/Ceres/src/Ceres.Chess/Ceres.Chess.csproj : warning NU1701: Package 'Google.ProtocolBuffers 2.4.1.555' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework 'net5.0'.

The build failed. Fix the build errors and run again.

I was told that this was a distro specific problem, hence I have approached this forum. Please help me in rectifying this issue. Thank you!

I think the dot-net that Ceres needs which is v4.7.1 is incompatible with the AUR dot-net which is 5.0 that's why it doesn't build. I don't have a solution though as I've never dealt with dot-net.
Why not just try other chess engines readily available for linux.

Re: Ceres (MCTS Chess Engine) not installing

It says in the requirements that it requires dotnet 5.0.0, at least in Windows. I have installed the dotnet framework 5.0.8, might that be an issue? I don't know how to install version 4.x
Regarding using other engines, I use Leela and Stockfish, but Ceres is 2x faster than Leela for my graphics card.

Re: Ceres (MCTS Chess Engine) not installing

According to the author of the engine, this was supposed to work.

I was told that this was a distro specific problem

https://github.com/dje-dev/Ceres/blob/main/Setup.md only mentions windows as supported.

We lack information and can only make wild guesses about what goes wrong.
I suggest you ask the author for clarification which linux distros are supported and instructions how to install ceres on one of those.

Once that is clear, maybe we can help to apply that to archlinux (and hopefully create a PKGBUILD for this).

Re: Ceres (MCTS Chess Engine) not installing

/home/divine/Ceres/src/Ceres/Ceres.csproj : error NU1101: Unable to find package Microsoft.NETCore.App.Host.arch-x64. No packages exist with this id in source(s): nuget.org

This is the error. It tries to find Microsoft.NETCore.App.Host.arch-x64 on nuget.org, but it does not exist.

If you search on nuget you can find a Microsoft.NETCore.App.Host.linux-x64 which is probably the right one.

Please note that this is as far as I can try to help, because I know nothing about .net or the build system Ceres is using.

Thank you! I will check this out. If it is solved I will mark as such.

[EDIT]

I got the following error:

Should I upgrade DotNet?

The Github needs to be updated. Linux is supported from version 0.91. With regards to the distros, he mentioned Ubuntu as one where it worked, but didn't know anything about Arch. I checked the Dotnet pages, and it gave instructions of installations for literally every other OS apart from Arch (not complaining about Arch just for clarity). Hence I was looking for a clarification here.
