 Hello list,

after the prior process of getting 2gb data conversion using gdal with
grass61cvs been a success.

i am facing a problem with terraflow process on the 2gb dataset(ESRI Ascii
Raster Grid) which i converted to grass raster grid file.

r.terraflow December 2003
region size is 19954 x 21199
cell newdata header compatible with region header
elevation stored as FLOAT (4B) WARNING: raster newdata is of type CELL_TYPE
--you should use r.terraflow.short

DELETED IN CASE OF ABNORMAL TERMINATION OF THE PROGRAM. TO SAVE SPACE PLEASE

and also seem not to process data above 1gb(ESRI Ascii Raster Grid) too.
is there anything else i missed while compilation of grass?

PS. i had this was my configuration, compilation and installation statement
from grass61cvs.

./configure --enable-shared --with-fftw --with-includes=/usr/include
--with-libs=/usr/lib --with-motif --with-freetype=yes
