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.

Hi LETRA,
do you get any error message?

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.
