Subject: GUI: r.terraflow: the window does not pop up, error printed to terminal
Platform: GNU/Linux/x86
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: 2006-04-12
in d.m:
1. Hydrologic modeling -> Flow accumulation for massive grids (r.terraflow)
2. error in the terminal:
$ r.terraflow December 2003
region size is 241 x 196
ERROR: Required parameter <elev> not set:
(Input elevation grid).
ERROR: Required parameter <filled> not set:
(Output (filled) elevation grid).
ERROR: Required parameter <direction> not set:
(Output direction grid).
ERROR: Required parameter <swatershed> not set:
(Output sinkwatershed grid).
ERROR: Required parameter <accumulation> not set:
(Output accumulation grid).
ERROR: Required parameter <tci> not set:
(Output tci grid).
Description:
Flow computation for massive grids (Float version).
Usage:
r.terraflow [-sq] elev=string filled=string direction=string
swatershed=string accumulation=string tci=string [d8cut=value]
[memory=value] [STREAM_DIR=string] [stats=string]
Flags:
-s SFD (D8) flow (default is MFD)
-q Quiet
Parameters:
elev Input elevation grid
filled Output (filled) elevation grid
direction Output direction grid
swatershed Output sinkwatershed grid
accumulation Output accumulation grid
tci Output tci grid
d8cut If flow accumulation is larger than this value it is routed
using SFD (D8) direction
(meaningfull only for MFD flow)
default: infinity
memory Main memory size (in MB)
default: 300
STREAM_DIR Location of intermediate STREAMs
default: /var/tmp
stats Stats file
default: stats.out
If r.terraflow GUI is called from CLI with r.terraflow&, the window pops up,
but there is still some unwnated output to the terminal:
$ r.terraflow&

Changing "spawn" to "term" in gui/tcltk/d.m/menu.tcl helps it start, but
probably isn't the correct solution.
Changing to "execute" gives a tcl error (maybe informative as to the
problem)

r.terraflow doesn't follow the correct startup sequence; it does some
stuff (e.g. G_get_set_window(), printing the region to stderr) before
G_parser() is called.
This will likely cause features such as --tcltk to break (Tcl's
exec/open functions will throw an exception if the process writes
anything to stderr).
