Install on Mac

[LETRA]

Good night,

I bought a Certabo board that arrived today and I'm trying to install your app on a Mac.

I have the executable downloaded from http://vt100.at/files/ and a very basic use of brew, pip, pip3, etc.

I have tried several methods to run "certabo-uci-osx" but I can't find the right one.

Some help would be very welcome or a few lines in the readme file.

All the best for you.

[haklein]

Hi LETRA, do you get any error message? br Hari

Hi haklein,

I don't know what is the command to install your package. I try:

[haklein]

The "certabo-uci-osx" file is a binary generated by pyinstaller. You might need to make it executable ('chmod +x certabo-uci-osx') and then just execute it in the terminal ('./certbao-uci-osx')

[haklein]

If you prefer to run the python script directly, you need to check the repository out from github.

[LETRA]

Thank you. I thought it was an installation package. Now there's a problem running it. Certabo_chess2.9_Mac has an error in Catalina. Pietro said he's going to send me some instructions on how to get the software to run.

Then I can use yours, in conjunction with ChessX for example?

[haklein]

Yes, you can use certabo-uci without the official Certbao software. It's standalone. Just make sure to run the calibration once, to add the pieces (you can set calibration via the UCI engine setting in your favorite chess program).

[LETRA]

Perfect. I just installed it on ChessX. Is the calibration via command line?

[haklein]

no, as stated in my previous update, calibration can be enabled via the UCI engine settings.

[LETRA]

Excuse me, how do I access the UCI engine settings?

[haklein]

that's usually implemented in the chess gui. The UCI engine tells the chess program what config settings it does support, and the chess program provides a settings page for that. In ChessX you would go to the preferences, switch to the Engines tab, select the certabo UCI engine, and press the "Options" button. That will open the Engine Options window specific to the certabo UCI engine (see screenshot).

[haklein]

[LETRA]

Got it. I change the value to "true", but nothing happens. The "add piece" option doesn't appear either.

[haklein]

The osx binary is probably from a version which didn't yet has the Addpiece option. Let's start from the beginning. The certabo board does use a Silabs USB virtual com port. Did you install the driver for that? Otherwise the Certabo wouldn't show up as com port on the mac. The Certabo uci engine does write a log file (I'm unsure where exactly that's stored below your home directory on the mac). This would also be helpful to debug any issues. But I guess that you didn't install the silabs driver (it can be found on the certabo homepage or directly on the silabs homepage).

[LETRA]

Yes, install the driver first, before the official software, with which there are several errors in Mac OS Catalina. Now I will look for a more updated version of ChessX or try XBoard or another program (although there are not many).

[LETRA]

I have updated ChessX to the latest version without the "add piece" option and XBoard closes when I configure Certabo UCI (also it doesn't have a button to configure the calibration I have seen). I don't know what to do. Maybe the software for Certabo is not yet mature for the public to use without developer knowledge.

[haklein]

LETRA, this software is provided by me as individual and not related to Certabo at all. Regarding maturity of this specific UCI driver: it works fine for me, I've played a lot of games using my UCI engine. Mostly with pychess, but I've also tried a bunch of other chess GUIs. From your previous posts on this ticket, I'd assume that you don't have experience with chessx, nor with UCI engines. chessx is a bit special, as it is more a chess database, also supporting engines. For anything to "happen" afte rconfiguring the UCI, you need to start an engine match in chessx, and configure the engine match so that one engine shall be stockfish, lc0, whatever, and the other engine to be the certabo UCI engine. Maybe you want to try some simpler chess GUI than chessx. Also my certabo-UCI engine is a special use case, as from a GUI perspective it's like an engine playing vs engine. That said, it works for me, your mileage may differ, but without a log file it's hard to tell what's going wrong for you (besides my assumptions above that you didn't start an engine tournament)

[haklein]

I forgot to add, if you want to use the "AddPieces" option (which is basically a calibration without resetting the existing data first, e.g. to add a 2nd pair of queens or another set), you can always take the latest version for this UCI engine from this github repo. The 'requirements.txt' file will list all python requirements (you can apply them e.g. by running 'pip3 install --user -r requirements.txt').

[LETRA]

Thank you very much for your help, Haklein. I have no experience with chess engines (many years ago I tried a little Arena and some UCI modules with Fritz 6 or 7) but I have followed all the steps you have indicated. I have been last night doing a Team Viewer session with Pietro and the problem is the driver. For some reason it's not working in mac OS Catalina. We have tried an experimental version that is adapting to this system, but the specific USB driver fails and is surely the reason why I can't use either the official app, or yours, on the Mac.

In Windows 10 LTSC (in my boot camp partition) the official apps work. I'd like to test yours too, if there are any executables or instructions.

[haklein]

@LETRA: that is weird, as I'm using the silabs driver from the Certabo homepage on macOS Catalina (10.15.3) on a Macbook Pro 2015. Albeit it asked me to change some security settings so that the driver would be run.

[haklein]

@LETRA: you need to allow the extension like shown here: https://developer.apple.com/library/archive/technotes/tn2459/_index.html

After that the silab driver worked fine for me.

[LETRA]

I tried it on an iMac 2017 and a newly reinstalled Macbook Air 2012, and on both it's impossible to run the official software. Pietro was connected to my computer via Team Viewer last night for almost two hours.

This is the error log (last lines in loop):

[LETRA]

Yes, of course the extension is approved. I think they have already verified that there are users who don't work in Catalina and that's why they are developing a new version.

[haklein]

can you do a "ls -l /dev/tty*" and attach the output?

[LETRA]

Pietro just sent me a driver and your engine is running on Hiarcs Chess Explorer !! :)

Ah perfect, so you're up and running. That's great!

Yeah, in your output I can see the silabs virtual com port: crw-rw-rw- 1 root wheel 18, 4 11 mar 15:05 /dev/tty.SLAB_USBtoUART

Enjoy your Certabo board! And just nag if you hit any issues with the UCI engine.

[LETRA]

Thank you very much for your app and your help (I'll give you the trouble to install it in Windows again) ^^ :)

[haklein]

@LETRA for windows, there is a project from Lars. Frankly I'm not sure if my code works on windows, as it does use fcntl locking, which is not available on win. While this would probably be easy to fix (use different locking on windows), the engine from Lars seems to be in a very good shape with nice documentation: https://www.certabo.com/certabo-forum/topic/certabo-uci-driver-by-lars-nowak/ I'm currently moving all certabo related code in a separate python certabo module, and will use that in my lichess client (already there), the lichess broadcaster and the UCI engine (pending). After that has been done, I'll maybe find time to ensure that this python-certabo module will also run fine on windows.

[LETRA]

Thank you! I'm going to try the Windows app later, but I spent a couple of hours installing your Lichess app on these two computers and I'm very satisfied. I have the impression that it is simpler and more solid than the official app. Also, the moves respond faster (mine and the opponent's) and it doesn't waste so much time. I think the drivers for Chrome and Firefox used by the official app are less solid. I have played two games in Lichess with Safari and without any bug except add piece that doesn't work. I am very happy to use the Certabo board on the Mac for playing online, which is my main operating system. When add piece works in calibration I think I will turn on little Windows for this :)

@LETRA the lichess code is very fresh, just a few days old, but I'm also very happy with the current results. I was talking to Pietro from Certabo, and there will be efforts from them to integrate my board API client code into their GUI and hence make it easier to install and use for users. The official app for the online platforms was released by Certabo before lichess did provide a board API. So it is not using that yet, but hooking into the browser to "simulate" a human interacting with the webpage. That has some drawbacks, as you do see e.g. in regards to speed. AddPiece will be easy to add, I just didn't provide a commandline switch for that yet. I'll do that these days. Nice to hear that you're happy with the code. Thanks for the feedback,
