Hello, Any news regarding Chess X with Mac os tahoe? Does it work?? groucho@users.sourceforge.net Le 31 oct. 2025 à 22:57, Jens Nissen hognose@users.sourceforge.net a écrit : This is a wild crash-dump - I'm not expecting so many threads at the same time in DatabaseInfo. I have no idea what's going on. What steps did you do to get into this? Was the Opening Tree open at this time (it is the only tool that is using threads and might interfere with the remainder of ChessX) [bugs:#362] https://sourceforge.net/p/chessx/bugs/362/...

The crash is not always and happens sometimes at random. It happen when I just open Chess X and open my full database with my 101 pgn files( opening tree is not open to my knowledge) When it happens, I try again and sometimes it works or I open the data base files in several steps meaning not all at once. My data base has 101 pgn files whose max individual size is 260k. Do you think Chess X is ok under new mac os Tahoe 26,0,1? Many thanks.

I can't call it a major bug, it's rather some syntax error in code. Let me explain why I think so: 1) STEP 1 I donwloaded the latest ChessX code (it was 2nd of September 2025 that upon a time) and used Qt,.15.2(MinGW.8.1.0) to qmake and then make Let me point out I was always using this one on my Windows and it was always compiling well. This time it compiled successfully as well 2) STEP 2 When I opened the program and tried to open the ctg. tree as database - program reported "File not found". By...

I can't see any error on Mac OS or Windows 11 - can you show the steps to reproduce? Which Qt version do you use - there are quite a lot og buggy versions so I still compile ChessX with Qt5.15.2 which is the only stable version I could identify for Windows. I am using 6.9.1 for Mac OS which is fine. Especially versions below 6.8 should be discarded due to severe bugs.

Yes, it's Windows 11. But what's annoying, I always had this problem. It was the same issue on Windows 10 as well. Installed from preinstalled exe. or compiled from source it's always the same issue. What's important it's only about CTG. ABK works well (quite slow for multi-million games database, but it finally loads and works) LICHESS DATABASE works well and is super fast. Only CTG doesn't load at all. All dlls are there, CTG files are not corrupted. It's either something in the code itself, or...

wow - very unexpected. If you make a move on the board, will the list then populate? I remember an issue where I forgot to update the list in some obscure cases (like changing the active database) and I saw another one yesterday when closing the ctg (the list was not deleted in this case). Is this Windows 11?

Dear Jens. Of course I know about combobox in opening tree, but that's the point it's empty even if I upload your hiarcs.ctg You can see that on photo

I like the way lichess does this and I think I will implement something like that in the near future

CTGs don't work like standard databases as they cannot be written to nor do they contain games. They only work via the Opening Tree. So you open a CTG like a database and then you select the CTG in the combo box of the opening tree (! - this is what you probably missed - by default, the combobox is on "database" and applies to your current database which has a board representation, but a CTG doesn't have one) . I am using the opening book here as reference: https://www.hiarcs.com/book-downloads/H12Book.zip...

apologies for the bug name. at one point, i could not find AUTO RESPOND, as the icon/image/button was hidden by other icons/buttons/images, and it wasn't obvious AUTO RESPOND was there until i decided to try moving those icons/buttons/images around... true title: UNABLE TO PLAY AGAINST ENGINE thanks :)

How can I improve the speed of Opening Book Tree? I am running an opening book using an indexed database of about 5 million games. The speed of search is really bad and takes up to 5 minutes to search. Is there any way to improve this?

The ChessX Wiki on SourceForge says "Compiling the source is simple. Just unpack the sources, go to source directory (chessx) and execute: lupdate chessx.pro qmake make" Is there a command-line compiler I can run in the Windows OS to execute those commands? Instead of installing and learning how to use the Qt Creater IDE?

I know that there is (was?) a Qt extension of Visual Studio, but I haven't used it for years now. At least this extension is required for handling the moc'ing and the language specific handling of the sources. As this extension was always kind of tricky, I would prefer the Qt Creator for compiling chessx.

I am trying to compile ChessX in Visual Studio on Windows. I installed the Qt library package into Visual Studio. I cloned the ChessX source code repository from Github into Visual Studio. Visual Studio does not accept chessx.pro as a valid project file, even after I rename it to chessx.proj. I opened chessx.pro in an edit window and tried to compile, but I get multiple compiler errors related to CMake. I could not find a qmake file. I tried opening a command prompt window in the source directory...

I have solved it but it was complex. For information : Needs to go in keyboard and mouse parameters access & authorisation and logitech software access authorisation probably modified by software update. I would have like an additional features on chessX : counting on side panel, the list of pieces black & white captured or alternatively the numerical advance or decline by conting the pieces value balance.

I bought my son a M2 Mini so if he let's me onto the device, I might compile a ARM64 version. There is next-to-nothing Intel specific so I don't expect any issues at all (there is one method in the bitboards where I use some assembly, but there is a C-Code version in the sources to use ChessX on non-Intel platforms)

local syzygy

I have no plans for integrating local databases: they are too small to be really useful and there is no API available to access them. You might use a local Stockfish to access the local copy - syzgy was originally developed for stockfish.

Yes, it's WINDOWS 11. In general, just as an idea, maybe it makes sense to make an "update" option for the program? Because, as far as I understand now we just need to uninstall and install it back after each new version.

At 1) I know, part ofthe problem is the Qt WIdget which is representing HTML not completely correct. I want to fix it with a new widget or a widget based on a different base class At 2) Thanks for finding this, I'll look into it.
-
It seems that problem is even more important, I thought that maneuvers are coded well, but it seems 1.6.2.0 version adds a wrong comma to maneuvers as well and it incorrectly looks as, say, { [%cal ,Ge4d5] } It definitely has to be fixed
-

Problem is allegedly solved by deleting the AppData folder left after the previous versions. But I still don't find it normal that previous versions intalled affect the newly installed version. Still looks like semi-bug at the very least

but when analysing, the piece moving pretty lag to follow my mouse. Can you fix it and add a small feature. An option to slective "just analysis this site". It's like after i chose black, it only analyse black turn, when it's white turn it just auto turn off the engine.

oops sorry i didn't read the manual carefully. Anyway thanks you for making such a great app

There is a selection list in the Annotation pane. I actually do not like modal dialogs as they intercept the flow when strolling through a game. You can also switch through parallel lines by pressing and <up> or <down> to get to the next / previous variation.</down></up>

Hi, At least I see that chessx runs OOTB on Ubuntu 24.4 with Gnome + X.Org. AFAIK there is a lot of software that doesn't work (well) under Wayland. So at least there is a simple workaround. In any event, this would be relevant for whoever builds the apt package for chessx. /Ejner Den lør. 10. aug. 2024 kl. 15.52 skrev Munzir Taha munzir@users.sourceforge.net: This is Ubuntu and I just did apt install chessx.

Ask which move when multiple are posibble

The tablebases are used online: whenever the tablebase enters a known position, the result and the moves are automatically shown in the Analysis pane #1 (even if no engine is running). Currently searching is indeed an issue in textbase format - at least, if the database is above the limit where it is not loaded into memory (see Preferences->Database->Edit PGN files smaller than). But as I am not too familiar with database design, I have not delved into the design of a new format. Especially now that...

The 5 piece tablebase is approx. 1GiB which imo is reasonably, while 6 pieces is 150Gib which indeed is too large for most. Is there already an option to use these? Since I might have missed this then. My reasoning for a different database format is speed. A Find position with ChessX in Caissabase (3G) takes many minutes. I suppose this is due to storing it as PGN. Are CQL supported now? and would implementing those differ for PGN vs. any other format? My intention would in the end be to have functions...
-
I am using Sygy online as the offline bases are far to large for any reasonable computer. As to the internal database format: I was thinking of using a open source file based database but as it has to be available in all major platforms and I'm not a database designer and it has to be really fast in the end probably supporting cql queries in user friendly manner (otherwise - why have an internal formmat?) I have not really started to implement anything. If you want to implement something - just copy...
-
Yes this works, thanks. Is there any intention to support Syzygy tablebases and using a different database format instead of PGN and would you want me to work on either?

ChessX is inefficient when making moves on very large games

Indeed loading the game takes a short time (I guess, it's the notation widget (=HTML generator and document browser) which stalls a bit) but once loaded, I can see no real delays.

The parser used to use the blank as token separator. Most of the "blank" issues should be gone in the upcoming release. Note that I trim all leading and trailing spaces from comments though. And also notice, that multiple spaces do not become visible in the game notation within ChessX (even though they are saved and can be seen in the comment dialog box) as ChessX uses a HTML browser to display the notation - the browser contracts multiple spaces magically. If you still find issues in the upcoming...

Did you compile with QT_QPA_PLATFORM set for wayland and did you install the wayland plugins into the plugins folder? There should be at least 3 directories for wayland in plugins.
