 Reporter:  martinl      |      Owner:  grass-dev@…
     Type:  defect       |     Status:  new
 Priority:  normal       |  Milestone:  7.6.2
Component:  Raster       |    Version:  svn-trunk
 Keywords:  r.watershed  |        CPU:  Unspecified
 Platform:  Unspecified  |
-------------------------+-------------------------
 r.watershed source code says

 {{{
     /* Check for some output map */
     if ((opt8->answer == NULL)
         && (opt9->answer == NULL)
         && (opt10->answer == NULL)
         && (opt11->answer == NULL)
         && (opt12->answer == NULL)
         && (opt14->answer == NULL)
         && (opt15->answer == NULL)) {
         G_fatal_error(_("Sorry, you must choose an output map."));
     }
 }}}

 but there are more output raster maps defined, eg.

 {{{
     opt13 = G_define_standard_option(G_OPT_R_OUTPUT);
     opt13->key = "length_slope";
     opt13->label = _("Name for output slope length raster map");
     opt13->description = _("Slope length and steepness (LS) factor for
 USLE");
     opt13->required = NO;
     opt13->guisection = _("Outputs");
 }}}
