Hello,
After the normal procedure of downloading and extracting it, I installed in MXLinux the LeelaChess engine for Scid_vs_pc from github:
I can’t get it to install on Manjaro or here on Endeavouros and I don’t see what I could be doing wrong.
The version in question is v0.26.1 and the file is marked as:
Source code (zip)
I installed eigen from octopi that was not installed, also meson … Any other ideas ?.
Check the link here:
I don’t know what to say to this, it is installed and runnig in my MXLinux without anything else except the normal follow up for this kind of installations on Scid …
Not sure if this solves your issue but lc0 is available in aur
$ yay -Ss LeelaChess
aur/lc0 0.26.1-1 (+0 0.00)
UCI-compliant chess engine designed to play chess via neural network, specifically those of the LeelaChessZero project.
So try install like this yay -S lc0
I gave it shot, but didn’t proceed beyond the first stage, see screenshot below

Are you going to cross-post regularly?
If so, I’d recommend you pick one forum so you don’t split effort, and then people on one or the other get the full picture rather than just the part you show them.
what’s wrong? im trying to find help. Are you not too in the two forum?.
This file is no longer available from that location. The default neural network file 703350.pb.gz is available in the Windows zip file though. You’ll need to extract in and update the PKGBUILD to use it. If that’s a bit too complicated for you, stick to Stockfish. For all intents and purposes any chess engine for the average chess player is going to be more than useful enough and you wouldn’t be able to appreciate the difference between stockfish and lc0.
EDIT:
To explain a bit more thoroughly, you’ll need to download one of the windows zip files from this page: https://lczero.org/play/download/
Inside the zip file is 703350.pb.gz, this is the file you’re currently having issues downloading. You’ll need to place this in the same folder as the PKGBUILD and use its filename instead of the URL in there. From there, rerun makepkg -s. Somewhat in the middle of something at the moment, but if someone has the time to give more of a play by play it might help Keos.
As you said … for the average player. Of course!. But is it my case?.
Are you one of the top 100 GMs? 
If so, I’d love a game and be more than happy to walk you through the entire process 
when I was twelve years old I was already giving chess simultans in the capital of my country …
Cool, what’s your FIDE rating?
EDIT: Joking aside when I have time I’ll post more detailed instructions.
it was 2400 in usa around 1990 probably, now i’m 67 years old and don’t play chess any more … hight blood pression … etc.
OK my friend, after taking a few mins to look around I found an alternative download to the weight file and updated the PKGBUILD. Use the following and you should be right. I was able to build lc0 without a problem

No, i can’t understand this, you forgot this is a ‘newbie’ room … means around 800 Elo.
Just for you my friend, here’s the package already built: http://www.alenbasic.com/lc0-0.26.1-1-x86_64.pkg.tar.zst
Once you have downloaded that file from a terminal in the directory you downloaded it to, you can install it with sudo pacman -U lc0-0.26.1-1-x86_64.pkg.tar.zst
it was right to the dowloads section but it can’t be extracted
and later by the terminal:
keos@keos-pc ~]$ sudo pacman -U lc0-0.26.1-1-x86_64.pkg.tar.zst
[sudo] password for keos:
loading packages...
error: 'lc0-0.26.1-1-x86_64.pkg.tar.zst': could not find or read package
[keos@keos-pc ~]$
i tried again with another aplication/option by right click … and it says the extraction was completed (it create a new file at the download section: ‘usr’).
Then i apply again the command but:
[keos@keos-pc ~]$ sudo pacman -U lc0-0.26.1-1-x86_64.pkg.tar.zst
[sudo] password for keos:
loading packages...
error: 'lc0-0.26.1-1-x86_64.pkg.tar.zst': could not find or read package
[keos@keos-pc ~]$
It looks like you’re in your home folder… try this:
Open a terminal and do the following:
cd Descargas
ls
if you see lc0-0.26.1-1-x86_64.pkg.tar.zst then run sudo pacman -U lc0-0.26.1-1-x86_64.pkg.tar.zst
EDIT: updated command based on your locale.
First, let me show you this; ‘Descargas’ means Download:
[keos@keos-pc ~]$ cd Descargas
