OK, I see what the problem is. And it is in uci2wb. This should split the doeble-move that UCI engines print into two separate CECP move commands, one for the FIDE piece and one for the Duck.

The version you have doesn't do that, and this confuses XBoard. So it does not send the same Duck move to engine 1 as that it received from engine 2. And that of course will cause inconsistencies that lead to illegal moves.

It appears that the patch I made for this to the UCI2WB I included in the WinBoard Duck Chess package never made it into my on-line repository for UCI2WB. There should be the following piece of code in UCI2WB.c:

Code: Select all

	    if((q = strchr(line+9, ','))) {
	      *q++ = 0;
	      Move4GUI(line+9);
	      printf("move %s,\n", line+9); // send first leg
            } else q = line + 9;
	    Move4GUI(q);
	    printf("move %s\n", q); // send move to GUI

The last two lines are there in the repository version, (except they use line+9 instead of q), but the preceding if-else clause, which is responsible for splitting moves that include a comma, is not.

Since the problem seems to be that running ./autogen.sh does not produce a file ./configure for you, I have run "make dist" (after ./autogen.sh and ./configure) on my machine for the latest snapshot, to make a "distribution tar ball". Such a tar ball already contains the configure script, as the process involves running ./autogen.sh. This is the form in which XBoard sources are normally distributed. I uploaded it to

http://hgm.nubati.net/transfer/xboard-4.9.1.tar.gz .

It should be possible for you to build XBoard from that by running

./configure
make
sudo make install

I did a lot of research yesterday so I could compile your code for xboard. If we ever get this to actually compile, have fully documented everything for posterity ...

I ran these commands to clean up everything:

Code: Select all

sudo make clean
sudo rm configure
sudo find . -name Makefile.in -delete
sudo rm config.status
sudo ./autogen.sh
sudo ./configure

I attempted to make xboard using

Code: Select all

sudo make

But there seems to be a problem with duplicate definitions. I looked at the code itself, but only found 'ics_type' defined in backend.c.
Here are the messages that appear at the end of the make:

/usr/include/glib-2.0/glib/gtypes.h:553:8: note: declared here

[hgm]

The problem is in backend.h: this contains a line

enum ICS_TYPE ics_type;

and is #included in nearly every .c file. That line should be entirely removed, as backend.c already declares ics_type, and is the only source file that refers to it. (Otherwise there should have been an 'external' in front of the definition in backend.h.)

Anyway, I now pushed the patch I made in UCI2WB on behalf of Duck Chess to my on-line repository. You can download the latest snapshot there, and install it through

sudo make install

Thanks for updating UCI2WB - it seems to work properly now, since Mayhem makes valid duck moves.

When I played a game using MayhemDuck2.0 for both engines, it still triggers an illegal move. It plays the same moves each time, and 3.Bg5 is clearly illegal.

When I was testing Mayhem earlier I got a bunch of bunch of GDK errors while resizing the xboard window for engine output.

[rgrosz789]

When I played a game using MayhemDuck2.0 for both engines, it still triggers an illegal move. It plays the same moves each time, and 3.Bg5 is clearly illegal.

Maybe there is something seriously wrong with my Linux system?!

I have tested numerous version of Mayhem engines, and rarely get past 3 moves:

Code: Select all

White  Black     result
1.6        1.6      UCI2WB: mayhem16duck died on me

1.9        1.9      xboard failed: Segmentation fault (core dumped)
2.0        2.0      UCI2WB: mayhem20duck died on me

For the game with 1.9 versus 1.8 this message appeared in terminal

(xboard:4348): Atk-CRITICAL **: 14:55:13.495: atk_component_add_focus_handler: assertion 'ATK_IS_COMPONENT (component)' failed

[hgm]

The GTK errors could be caused by running a binary made for one distro in another, with slightly incompatible libraries. As long as they don't crash XBoard I would just ignore them.

What is more serious is that this version of XBoard appears to totally mess up the move it receives from the second engine. E.g. it receives d7d5,d5d2 from the second engine, but then it sends d7d5,d2c5 to the first. It is a mystery where this d2c5 comes from. Since g8f6,f6e4 becomes g8f6,e4g6 it seems to use the received Duck to-square for the from-square of the Duck move, and the rank number of the to-square it cooks up seems to come from the rank of the FIDE to-square, but how it pulls the file of the to-square out of the hat?! The insane thing is that from first to second everything works fine. While this is handled by exactly the same code.

I thought other people had used XBoard for Duck Chess, and I never received any complainst until now. I will try to figure it out.

I thought other people had used XBoard for Duck Chess, and I never received any complainst until now. I will try to figure it out.

I use your newest version of Winboard (in Windows 10 OS), which you offered in this thread, and it works like a charm.
Have not tried the new Xboard version yet, and have expected that it has the same functions like Winboard, just written for Linux systems

[rgrosz789]

Maybe there is something seriously wrong with my Linux system?!

I have four computers running Linux, so I decided to try setting things up on the laptop that I use to control my coffee roasters. It is a Toshiba M780 from 2010 ...

I never actually got to play a single move of Duck Chess. None of the engines load - sometimes I get permission denied, sometimes xboard crashes.

Here are my notes:
Linux Mint - Toshiba M780
02/26

sudo apt update
sudo apt install xboard (2016 version)
sudo apt install build-essential

standard xboard software uses Polyglot rather than UCI2WB as UCI adapter.

Downloaded latest UCI2WB source from HGM
http://hgm.nubati.net/cgi-bin/gitweb.cg ... ;a=summary
Then run 'sudo make install', which copies executable to /usr/local/bin

Downloaded the executable file for xboard with Duck chess from HGM
http://hgm.nubati.net/transfer/xboard.gz

That xboard can't locate images for chess pieces
Need to extract source files for xboard with Duck chess from HGM:
http://hgm.nubati.net/transfer/xboard-4.9.1.tar.gz

Copy all files from the svg directory in the distribution tar ball to
/usr/local/share/games/xboard/themes/default/

Hmmm - that directory doesn't exist?!
sudo mkdir /usr/local/share/games
sudo mkdir /usr/local/share/games/xboard
sudo mkdir /usr/local/share/games/xboard/themes
sudo mkdir /usr/local/share/games/xboard/themes/default/
sudo cp ./chess-sources/xboard-4.9.1/svg/*.* /usr/local/share/games/xboard/themes/default/

Need to save the xboard settings
sudo mkdir /usr/local/share/etc
sudo cp ./chess-sources/xboard-4.9.1/xboard.conf /usr/local/share/etc
xboard still says it can't save the settings!

Need to set execute permission for all versions of chess engines
Then copy files to correct location
sudo cp -p ./Downloads/MayhemDuck-2.0/mayhemduck-2.0-x86-linux-64bit /usr/games

Also used my compiled Fairy Stockfish for Duck (from Dell XPS 8300)
sudo cp -p ./Downloads/FSFDuck /usr/games

Nothing works!



Not much appears in xboard.debug either:
