Apologize crossposting, i wrote these mail to the user list,
maybe better here on the dev too.
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@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 :

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,
