[GRASS-user] GRASS pygrass - composite

[Pierric de Laborie]

I have just tried to start the same command from the GRASS shell  (same
machine and same GRASS database and location) and it gets stuck also.

GRASS 7.0.0svn (222):~/Grass_test > r.composite red=B5 at PERMANENT
green=B4 at PERMANENT blue=B3 at PERMANENT output=mycompo
Creating color table for output raster map...
0..6..12..18..25..31..37..43..50..56..62..68..75..81..87..93..100
Writing raster map <mycompo>...
0..

Running the same command in GRASS GUI (command shell) on Windows works fine
and creates a composite in a few seconds. I am starting to think that it is
due to the way I installed Grass on this Linux machine (I used the
following link
http://grasswiki.osgeo.org/wiki/Compile_and_Install#GRASS_7_on_Debian_Wheezy
)

Thanks
