Do you already have an engine in mind? Both UCI and UCCI Xiangqi engines
exist. Most are closed source, but many are free. But alas, only
available as Windows binary. Elephant Eye is an intermediately strong
open-source UCCI engine that can be compiled for Linux.
The way to run UCCI engines is use the uci2wb adapter (obtainable from
the git repository at hgm.nubati.net), with an -x flag. So you would
have something like
xboard -fcp "uci2wb -x eleeye"
assuming that uci2wb and eleeye are in your search path (e.g. in
/usr/games/). If not you would have to specify the directory, e.g.
xboard -fcp "./uci2wb -x ./eleeye EleeyeDirectory" -fd uci2wbDirectory
I guess you could run Windows binaries by invoking wine (using two
levels of quoting)
xboard -fcp {uci2wb -x "wine someWindowsXQengine"}
but I have never tried that. I remember Kou was a pretty strong free XQ
engine. For UCI engines you would not have to use the -x flag with uci2wb.
If you plan to run many different UCCI engines you can configure XBoard
to make the -fUCCI flag work. To this end you must run XBoard once as
xboard -uxiAdapter {uci2wb -x "%fcp" "%fd"}
and after that you can use
xboard -fcp anyUCCIengine -fUCCI
to automatically invoke uci2wb (which must be in the system's search
path, or you should have given the full pathname in the -uxiAdapter command.

Hi:
I'd like to run the newest version of xboard with a Chinese Chess
engine. Is there a step by step guide on how to do this? Also, I
noticed from the page when the chinese chess engines are available
that the most powerful one is "closed-sourced" (so nonfree?) as it is
stated in the page linked from gnu.org/s/xboard
<http://gnu.org/s/xboard>. What is the recommended free engine for
chinese chess?
Apologies if this has been discussed previously, but I haven't found
it (yet) in the archives.
Thanks,
Loic
