[GRASS-user] r.terraflow on windows grass6.4 RC2 (osgeo4w)

[massimo di stefano]

Hi,

i'm tring to use grass on windows (osgeo4w.exe installer)
but "r.terraflow" give me some prblems

on the spearfish dataset :

r.terraflow.short elevation=elevation.10m at PERMANENT  
filled=elevation10m.filled direction=elevation10m.direction  
swatershed=elevation10m.watershed accumulation=elevation10m.accu  
tci=elevation10m.tci d8cut=infinity memory=300 STREAM_DIR=C:\tmp  
stats=stats3.out


MFD flow direction
D8CUT=999999986991104.000000
Memory size: 300.00M (314572800) bytes
Memory manager registering memory in MM_IGNORE_MEMORY_EXCEEDED mode.
raster elevation.10m is of type DCELL_TYPE --precision may be lost.

STREAM temporary files in /var/tmp  (THESE INTERMEDIATE STREAMS WILL  
NOT BE DELETED IN CASE OF ABNORMAL TERMINATION OF THE PROGRAM. TO SAVE  
SPACE PLEASE DELETE THESE FILES MANUALLY!)
file stats3.out exists - renaming.
ami_single_temp_name: mkstemp failed: : No such file or directory
Assertion failed: 0, file ami_stream.cc, line 75
This application has requested the Runtime to terminate it in an  
unusual way.
Please contact the application's support team for more information.


in the file stats3.out i have :

Free Memory=-1

it don't produce any output (onlt the stats file) and terminate  
immediatly

have you any idea ?

i manually created the directory tmp in C:

p.s.

is these an osgeo4w probles?
do you know any grass-windos version that has r.terraflow working?

i'm really new to windos (never used it) ... so maybe i'm doing  
something wrong :-/
i'm tring to make a foss-gis migration at university (idrology)
so i need a bit of time to port all the people on linux :-/
.... where r.terraflow works great and with really good results!

thanks to All,
