	Non alphabetic characters as options ? by John Darrington-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I'm trying to use '?' as a short option character, since I've used -h for other purposes. Unfortunately, this doesn't seem to be allowed. Is there a work around for this? gengetopt:6: syntax error ? gengetopt:6: option "help" ? "Show help information" gengetopt:6: ^ make: * [cmdline.h] Error 1 -- John Darrington jmd@...

"Show help information" > gengetopt:6: ^ > make: *** [cmdline.h] Error 1 Hi John It looks like getopt_long uses ? for its own purposes, see the man page: If getopt() does not recognize an option character, it prints an error message to stderr, stores the character in optopt, and returns `?'. The calling program may prevent the error message by setting opterr to 0. so probably, I don't know whether it is possible to do this... any clue anyone? -- Lorenzo Bettini, PhD in Computer Science, DSI, Univ. di Firenze ICQ# lbetto, 16080134 (GNU/Linux User # 158233) HOME: http://www.lorenzobettini.it MUSIC: http://www.purplesucker.com http://www.myspace.com/supertrouperabba BLOGS: http://tronprog.blogspot.com http://longlivemusic.blogspot.com http://www.gnu.org/software/src-highlite http://www.gnu.org/software/gengetopt http://www.gnu.org/software/gengen http://doublecpp.sourceforge.net _______________________________________________ Help-gengetopt mailing list Help-gengetopt@... http://lists.gnu.org/mailman/listinfo/help-gengetopt
