My apologies for bulking the questions, I haven't realized that was wrong. Some updates on my issues: 1) I have read your explanation about lichess tree, but may I ask you to give some tips on how to use it as it used to be in older versions. As I told you, it doesn't load even with APIs 2) It seems it was my mistake. My ctg. tree was generated in ChessBaseReader and it seems to have some limitations.

Please do not post multiple issues within one report as this makes tracking errors impossible (if I fix one issue and the other is open, I close the report thus the still open issue is lost as item to fix). Second thing: please always try to give a sample database: things that might be obvious to reproduce for you might not be for me - like the Windows Open file issue (Bug #361) that took me nearly a year to understand - fixing was a matter of minutes afterwards. Now coming to the issues: 1) The...

You could add a transparent piece set into the data/themes folder (do not forget to copy out all other themes into that folder so that you can change between transparent and non-transparent pieces). You could also make a hint set where all pieces are simple circles so that you can only see, where pieces are but not which piece. Combine this with training mode so that you cannot see the moves.

I am a bit at a loss with this request - if there is an existing working package - why should I bother to make changes? Or asked the other way around: if it is not working - what will need to be addressed? I actually do not support Unix packages as whenever I make one change for one distro, I immediately get complaints from other distributions.

Remember folder path when exporting a pgn database in Windows 11
-
If you have all your databases in one folder, you could switch the default database folder in the settings (Preferences->Database). I wouldn't want to follow with the default database folder the last file, as this might lead to databases being spread all over the disk. I have so many programs where I save a file and then have to ask myself afterwards: where has the file just gone?

Not sure if this is related, but... I installed Fedora 43's chessx (I know it'sa couple patch levels behind) and the first time I ran it, it said it was downloading some database (not the lichess/chess/.com/fics, something else) and it failed. Getting a lot of this: qt.network.ssl: No functional TLS backend was found qt.network.ssl: No functional TLS backend was found qt.network.ssl: No functional TLS backend was found qt.network.ssl: No TLS backend is available

That small D:\ was a hint - I can see the bug now as well and will fix it in the next few days. I'm not working with Windows-style paths at all on my computer which is why I did not see this error (all my URLs are something like //mac/Home/Documents/...)

I can confirm I do no see that. The initial situation is that I need to open a database, so I try to open it (see screenshot try-open.jpg) and nothing happens. If I try from the menu File > Open, it does not react either. If I drag and drop the PGN file, the database is imported correctly (see screenshot drag-drop.jpg). Then I set it to be opened at startup (see screenshot active.jpg) but when I relaucnh ChessX, the name of the database is the widget but it looks like it is empty (see screenshot...

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

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...

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 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)

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.
