Certainly, and I believe this is the right place to ask it. I use
archlinux. To build, I do the following:

git clone https://github.com/isarhamster/chessx code
mkdir build && cd build;
qmake6 CONFIG+= debug ../code
make -j 45

I don't think the project compiles with QT5, although I understand there
are many references to QT5. Are you still having problems?

Hi,

I wonder if this is the correct mailing address to ask such questions?

I cloned the master branch from https://github.com/Isarhamster/chessx.git

the INSTALL.md says run
    qmake
and then
    make

qmake doesn't do anything on my machine. Perhaps there are some parameters
needed to create makefiles?
It's also said that one needs QT5, but it's not clear to me which part I
need to install to make it compile.

I was running the official chessx package from Ubuntu, but that's version
1.4.x and had issues with the window management. Hence my motivation to get
a newer version on my machine.
The link to "all binaries" also links only to the windows installer.
The status of the project is confusing in a way because it's not clear to
the uninitiated like me, whether Sourceforce or Github should be the
authoritative source.
there's no active bugtracker on Github for the project and no wiki
configured. But some of that seems to exist on Sourceforge.

May I ask for some advice?

Dear ChessX Developer Team

Do you plan to release android version of your database?

I would very much like to have access to it via my mobile phone.

Keep up the good work.

Kind Regards

QT_QPA_PLATFORM is a Linux environment variable (to be set on the computer executing a program) - not a build variable of a program

Hi,
Thanks Jens. I tried to but I did not manged to do it working.

On the page https://doc.ubuntu-fr.org/wayland (it is in French but I am
sure it is somewhere in english), they suggested to place the variable
QT_QPA_PLATFORM=wayland-egl

I tried to put that in the chessx.pro and make again. But nothing yet.

Is someone managed to compile ChessX under Ubuntu Noble with wayland window
system ?

Rgds,

Xavier - still looking for...

Wayland seems to be extremely broken - I installed it once and afterwards, I had to reinstall my Ubuntu to make Ubuntu usable again.
Many reports of these issues can be found on the internet.
You might take a look at the plugins missing in the wayland installation, e.g. here:
http://qcad.org/archives/lib/wayland_plugins.tar.gz

Cannot try this myself, as mentioned above, I won’t ever install it again.

Hello,

I got an older version of chessX and was really satisfied.
I needed to format the PC and I am not able to have it anymore.

The PC is a DELL Latitude E7440. I run it with Ubuntu 24.04.1 LTS.

I made lot of trials to compile the code, but I am totally lost now.

To take it by the beginning, I downloaded the source files. I change the
chessx.pro to comment out the CONFIG SOUND.
qmake is ok. The Makefile is attached herein.
make encounters the SOUND issue. That's why Jens modified the mainwindow
code last month. I have downloaded the two files (mainwindow.cpp and
mainwindow.h) and replaced in src.
making again,
I have numerous warning, with for example src/gui/mainwindow.cpp:2610:36 a
playSound with unused variables... why not ? Still some playSound getting
around.

The make goes to the end. A release folder is created with a chessx file
inside.

Then I launch chessx and the command line answer :

QSocketNotifier: Can only be used with threads started with QThread
qt.qpa.wayland: Failed to load client buffer integration: "wayland-egl"
qt.qpa.wayland: Available client buffer integrations: ()
qt.qpa.wayland: No shell integration named "xdg-shell" found
qt.qpa.wayland: No shell integration named "xdg-shell-v6" found
qt.qpa.wayland: No shell integration named "wl-shell" found
qt.qpa.wayland: No shell integration named "ivi-shell" found
qt.qpa.wayland: Loading shell integration failed.
qt.qpa.wayland: Attempted to load the following shells ("xdg-shell",
"xdg-shell-v6", "wl-shell", "ivi-shell")

And here I am. It seems that it is not able to make a window... But I
cannot help him.

Please, is someone understanding something ?

Best regards,

Xavier

Hi everyone,

 I'm running CheesX version 1.6.2 on Debian. When I enter the preferences
window it is displayed disproportionately, the top edge exceeds the top
limit of the monitor. To use the window you have to maximize it. I've seen
this problem in previous versions. I compiled from source code.

Dear users and developers,

I have updated the setup files for Windows and Mac OS to 1.6.2
This is mainly an update for finally fixing the annoying UTF8 issues that had come up.
But there are a number of new features like loading tournament files from lichess.

I will now start to merge all new features from pull requests so new features should be coming up soon.
Thanks for your patience and thanks for all the help I got with this update!

Some notes:  
For Mac OS I used Qt 6 (Qt 6.5.3) - if you want to compile ChessX yourself and you want to use a newer release of Qt: read the notes here: 
https://sourceforge.net/p/chessx/wiki/ChessX%20and%20Qt6/

The Windows version is still on Qt5 - if you are patient enough to fiddle out all the SSL and zlib issues you could probably switch to Qt6.
I tested ChessX on Ubuntu 22.04 with Qt5 - you could probably transition to Qt6 - but same issues will arise as with Windows.
For a note on SSL take a look under 
https://sourceforge.net/p/chessx/wiki/ChessX%20and%20Linux/

The bugs inside Qt > 6.5.3, 6.6, 6.7 also apply to Windows and Linux - prefer Qt 6.5.3.

If you find any issues in ChessX, give me a note!

Have fun!

Jens

Without explicit information otherwise, I assume the process is something
like

1. Submit pull request
2. Project maintainer provides feedback (accept, reject, or request changes)
3. If changes are requested, make them or discuss
4. Project maintainer merges or closes pull request


> ...or shared agreement...


It's not a democracy. The repository is owned by
https://github.com/Isarhamster, so he will be dictating how things will
proceed.

It seems that at least some review of 101 has already occurred.  Is
there a lack of clarity or shared agreement regarding the next steps
to be taken, and by whom?  If so, then resolving that could allow 101
to make further progress.

I just created https://github.com/Isarhamster/chessx/pull/102 that begins
to address https://sourceforge.net/p/chessx/feature-requests/225/.

https://github.com/Isarhamster/chessx/pull/101 is also awaiting review.

I think I'm going to stop contributing to chessx until these contributions
are accepted or rejected.

In the changelog (https://github.com/madnight/chessx/blob/master/ChangeLog),
I see a bunch of "CR#2984375", etc. What are they? I'm guessing CR means
change request, and they look like ticket numbers from a ticket system. But
that's a REALLY high number of tickets!

Specifically, I'm looking at CR#3580030 (mentioned in 7e4997a440f5 (
https://github.com/Isarhamster/chessx/commit/7e4997a440f5) which implements
"human readable" FEN. What is "human readable" FEN? I was hoping CR#3580030
would shed some light on the matter.

I am also running ChessX (1.6.0.0 UNIX64 Qt5.15.11) on Arch Linux (actually Endeavour OS) and I also cannot reproduce this issue.

Kind Regards
Reinhard

That's it? It doesn't matter what position you set up? It doesn't matter whether it's white or black to move? You don't actually have to move the white king anywhere, you just click him, right?

I will try to reproduce this tomorrow.

Hello Aaron, I am the one you were discussing with on the github PRs.

I use both Windows and Linux, currently debian for simplicity, although 
I'm a slackware fan at heart, arch is of course, also fantastic.

Anyway, the ChessX dev has slowed significantly, although IMO still the 
best opensource Chess tool by a mile.

ChessX has an opening trainer of sorts, but it only plays one variation; 
the mainline.

I am actually in active development on an opening trainer currently, I'd 
be happy to show you.
It is already very functional, and spaced repetition is actually 
currently under development, too.

Perhaps email me directly to avoid cluttering up the dev list:

Unleo.com is the domain, chess is the username.

In strict accordance with
https://sourceforge.net/p/chessx/mailman/chessx-developer/thread/200610171321.11325.mrudolf%40kdewebdev.org/,
I am interested in development! I like chess, and I'm a software developer
by day. I use GNU/Linux (arch linux specifically), and it looks like chessx
and SCID pretty much run the market here. I've used SCID a bit and it seems
to work pretty well, but when it comes to development, I like C++ a lot.
(I've also started getting excited about Rust...)

The feature that actually made me `git clone` is opening training. I think
it would be nice if the trainer would keep track of my progress learning
openings and use spaced repetition to help 1) learn and 2) retain opening
lines, sort of like anki https://apps.ankiweb.net/.

I just created pull requests 94, 95, 96, 97 which cause me not to be able
to compile on my machine. It looks like there may be other ways of fixing
these particular issues in other pull requests, so maybe they will be
closed as "already fixed" some day! The nature of the fixes in my PRs
suggest that development on this project may be using different technology
than me (older or newer versions of QT or C++??). I just did `mkdir build
&& cd build && qmake && make -j 20`, but if I should be doing something
else, please let me know!

Talk to you soon!

Hello all,

I can help on french translation.
Is someone already doing this ?

Hi everyone,

As a stable version of ChessX for Windows still has issues with tablebases and so on, I decided to use the latest source code to build up ChessX from it.

Technical information: system Windows 10; QT version 5.15.2; build-up kit MinGW 8.1 64 bit

First problem after qmake/ make chessx.pro actions was with some dll. Some were always missing, then when added manually "..No QT platform plugin could be initialized. error" It was annoying, but then I figured out windeployqt.exe that comes with MinGW fixes these errors easily.

Finally, chess.exe is ready to go and has all folders coming with it, but...

- I was initially unable to find the "data" folder normally. In the stable version of ChessX this one is coming together with all other folders and you can find "database", "engines" subfolders in it, but not in this case. "Data" folder for some reason gets installed to AppData/Local and has only "lang" subfolder in it
- I don't know is it a bug or I do something wrong, but I can't adjust engine settings Mr. Jens Nissen recommended to change via

I did that in analysiswidget.cpp, but engine still shows only 1 analysis line as a default despite being adjusted to 2. Then I changed code to

ui.vpcount->setValue(2)

;

but it still opens engine with a single analysis line only. I ask to help me with understanding what I am doing wrong

This one and next ones are already not about code, but about potential improvements. Is there some way to build up an indexed tree for a big database? Because I have databases with a few hundred thousands of chess games. Database takes long to get opened, then on each move it builds a tree from scratch, not excluding the games are already not applicable. Chessbase, SCID, Arena all have extremely fast trees, it could be great to have a fast one in ChessX as well. Or maybe, it's already present? Do I miss something? Because, lichess.book in ChessX is extremely fast despite having millions of games in it

There is some problem with ctg. Chessbase trees are not opened with ChessX on my computer. I create trees via Chessbase reader. Yes, there are temporary trees, but there's a way to create a stable ctg. tree there with all ctg. ctb. cto. But neither stable, nor source code version manage to open those. As CB reader is a freeware, maybe stable trees created by it are actually different from those created by commercial CB version. But it's still strange as those are not temporary. Maybe some advice?

-

Also, it could be great to have a possibility to adjust some simpler shortcuts. As far as I understood from the mainwindow.cpp shortcut should always contain system key (like CTRL) and some usual letter key. For instance, I tried to make shortcuts for drawing arrows/circles identical to Chessbase, but I failed, it didn't allow me to make green color simple ALT as in CB, yellow CTRL + ALT, etc.

Sorry for a long message. Also, I apologize, if some things I wrote were dumb from technical point of view, I am not a programmer, just an avid chess player, who really likes ChessX
I hope for your help

Have a nice day all
