This error message would be printed when during parsing of options it runs into the end of the line or file when it expects a value. And it then litterally prints the option for which it expected the value.
>From this you can see that it did not object to your command line, because your command line contains only '-fcp', and not '-firstChessProgram'. That these mean the same is entirely coincidental; I expect you would get the same error message when you would do "xboard -ncp". The message must refer to something it reads from a settings file. The settings files are read before the arguments on the command line is parsed. As '-firstChessProgram' is a volatile option XBoard would never save it in the user settings file. So it must be in the master settings file, /etc/xboard.conf (or in some distros /etc/xboard/xboard.conf, or when you installed from source perhaps /usr/local/etc/xboard.conf). That file must somehow contain an syntactically incorrect -firstChessProgram option. But that is not the case in the version we distribute.
