From: Andre Noll Date: Fri, 12 Apr 2013 12:24:54 +0000 (+0200) Subject: Use self-made help to avoid recompilations on version changes. X-Git-Tag: v0.4.13~23^2~5 X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=042767ce;p=paraslash.git Use self-made help to avoid recompilations on version changes. This provides print_help() for all remaining commands so that we can get rid of the gengetopt generated help output completely. Hence the *.cmdline.[ch] files no longer depend on git-version.h which saves a lot of recompilations. --- diff --git a/afh.c b/afh.c index f02b47b1..9ab694cf 100644 --- a/afh.c +++ b/afh.c @@ -15,6 +15,7 @@ #include "afh.h" #include "error.h" #include "version.h" +#include "ggo.h" static struct afh_args_info conf; INIT_AFH_ERRLISTS; @@ -56,6 +57,16 @@ static void print_chunk_table(struct afh_info *afhi) } } +__noreturn static void print_help_and_die(void) +{ + struct ggo_help h = DEFINE_GGO_HELP(afh); + int d = conf.detailed_help_given; + unsigned flags = d?
