Neither Stockfish nor GPS Shogi support XBoard protocol; they can only be used on XBoard with the aid of an adapter. Stockfish communicates in UCI, and GPS Shogi in USI. The UCI2WB adapter can handle both these protocols. So to use these engines you have to
1) install uci2wb on your computer, 2) make sure xboard is configured to use UCI2WB as adapter rather than Polyglot, 3) use the -fUCI or -fUSI options when starting XBoard from the command line, (e.g. "xboard -fcp stockfish -fUCI"), or tick the UCI or USI/UCCI checkbox when you embed the engine through the Load Engine dialog. To make sure step (2) is realized you could open the .xboardrc file (where the user settings for XBoard are saved) in your home directory with a text editor, and look at the value of the -adapterCommand and -uxiAdapter. The value for these should be -adapterCommand {uci2wb "%fcp" "%fd"} -uxiAdapter {uci2wb -%variant "%fcp" "%fd"} Only if this would not work there would be a genuine problem. Note that GNUshogi is so buggy that it plays like total crap, and can randomly decide to overlook even mate in 1. There are a number of engines that are able to play decent Shogi on XBoard without adapter, though; in order of increasing strength these are Sjaak II, CrazyWa, Shokidoki and Bonanza (the XBoard version in my on-line repository http://hgm.nubati.net/cgi-bin/gitweb.cgi ). I am not sure the latter would be weaker than GPS Shogi.
