Hi Helli, please consider to switch your session to a English language locale, eg
export LANG=en_US export LANGUAGE=en_US export LC_MESSAGES=en_US Then more people may be able to follow the error messages you have sent. Apart from that: r.volume's "row -82" looks like an integer overflow to me. Just guessing... cheers Markus _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
