<div class="gmail_quote">Thanks Hamish for these answers and suggestions. In the meantime we did end up installing
version 7, so I haven't had a chance to test it on 6.4 yet.<br>
<br>
I was only running as root for installing the extension - I did create a
new mapset just to start grass since the root account didn't have
access to any of the other mapsets. I hope this is OK.<br><br>Regarding version 7: is the issue stability, that sometimes it won't
work at all? I am a graduate student, so down time is not critical.
But if experimental means the calculations could be incorrect, I guess
that would be more important. One of the other students is pushing for
version 7 since they like the new features.<br>
<br>
Should spgrass work with version 7? I saw comments in the mail archive
from over a year ago that GRASS <-> R was much better in version
6 compared to version 7, is the situation improved now? (It didn't work when I first tried
it, but I have not taken time to check the details yet...)<br><br>-Eric<br><br>On Wed, Feb 8, 2012 at 12:52 AM, Hamish <span dir="ltr"><<a href="mailto:hamish_b@yahoo.com">hamish_b@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</div>usually a bug report would be good, but g.extension is still<br>
a work in progress, so the mailing list is fine too.<br>

</div>I would hesitate to run GRASS as root. You might make it the<br>
owner of some files or a mapset which belongs to a regular user.<br>
(maybe set up an admin account to look after the PERMANENT mapset<br>
in a multi-user location?)<br>

<br>
</div>simple work-around first: run g.extension as your regular user<br>
and then sudo copy the resulting binary from $GRASS_ADDON_PATH<br>
into $GISBASE/bin/. done! (make sure it is chmod a+rx)<br>

</div>note i.landsat.toar is present in grass 6.5svn too.<br>
(and don't use trunk for work that really matters; it's<br>
experimental)<br>

</div>try g.extension from the command prompt, it's a different version<br>
than the one which runs from the GUI. Specifically it has a -s<br>
flag to install system-wide (same as the GUI version), but also<br>
a -u flag to install system-wide using sudo for the install step. AFAIK these are not terribly well tested so any feedback would<br>
be appreciated.<br>

<br>
</div>this generally happens because it didn't think you were in grass<br>
at the time.<br>
<br>
<br>
if you installed from .deb packages, make sure the grass-dev<br>
package is installed too.<br>
<br>
if you installed from source you can copy the i.landsat.toar<br>
source code dir into the imagery/ dir in the grass source code,<br>
then run "make" from in there.<br>
