Hi Jarek,
I downloaded and compiled grass 6.4 SVN last week. So I suppose my version
is not so old.
Is there a way of I know the version of a r.(command)?
May be some issue with Vista (again!) ?
Thanks for the reply

r.watershed.exe elevation=FabioASTGTM_S2526W04948_dem
stream=FabioASTGTM_S2526W04948_dem_rwatershed_stream_thres0100
threshold=100 --o
Should finish in a few minutes.
Where is this 4096 coming from in the original command? Should that be
memory=4096?
r.watershed.
With 7201 rows x 7201 columns, the in-memory version should use at most
1.6GB of RAM. There should be no problem running it all in memory (no -m
4096) on a machine with 6GB.

Hi Markus,
Thanks for the tips. In fact I made a mistake, because I thought that with

IIRC it was more generic memory problems which only showed up on
MS Windows. In those cases valgrind reported errors, just on
Linux they

Did exacly that about 2 hours after posting this question. Interesting that the

the S8, MFD(8), and Dinf are all ways to get flow accumulation. What
are the units? Grid accumulation? So if I were to multiply a flow
accumulation by the squared resolution of the raster input map
(50x50=2500m). I would get flow accumulation in squared meters and
then multiply by average areal

Hi all,
In fact I have a dell machine, with Vista 64bits that came with the machine.
I compiled grass 64 svn using Msys. Is there a way of I know if my grass are
running with 64bits? By the way, what I need to change to have sure that
grass was compiled to 64bits?

Dear all,
two weeks ago I compiled the SVN version of Grass 6.4.
I just downloaded the 6.4.0RC5 version available at
http://grass.itc.it/grass64/source/grass-6.4.0RC5.tar.gz
and tryed to compile under Vista/Msys 64bit.
But when I try to compile the RC5 version I get error

Thanks for the suggestion and the link to the changeset. It turns out I had

un-commenting it but I still got the same error.

Try:

Hi Milton,
That worked! Thanks so much for the suggestion.
I experimented with combining the forward slashes and the full pathname with
spaces (e.g. C:/Program Files/Internet Explorer/iexplore) and that also
worked. So it seems the cause was using back-slashes instead of
forward-slashes.
