A related issue -- I'd like to use r.external but I can't seem to get
it to work. I'm running wxPython for GRASS 6.4 (from the Osgeo4W
installation). r.external seems to work properly, but when I try to
display the result, I get an error message telling me that
GDALAllRegister can't be found. Here, I've reproduced this in the
spearfish60 dataset:<br>
<br>
<p class="MsoNormal" style="margin-bottom: 0.0001pt;">r.out.gdal
input=elevation.10m output=elev_dem10.img format=HFA type=Float32<br>
r.external
input=elev_dem10.img output=elev_dem10_rext<br>
d.rast
map=elev_dem10_rext</p>
<br>
The layer shows up in the layer manager as "raster (double-click to set
properties)". I double-click and the name changes to
elev_dem10_rext@user1...<br>
<br>
Then I try to Zoom to Layer, or click on the Display Map button and I
get:<br>
<br>
Execution fiailed: 'd.rast.exe map=elev_dem10_rext@user1 --q'<br>
Details: <br>
Error: Unable to locate symbol <GDALAllRegister><br>
<br>
(By the way, I've also encountered this error message trying to do
r.mapcalc on a GRASS file imported using r.in.gdal.)<br>
<br>
Has anyone encountered this error? Is there a way to fix it?<br>
<br>
Thanks,<br>

But in order to save time and disk space I would like to

How do I link to a raster and vector data in another
location presuming it has the same projection?

add the mapset as a symlink to the mapset in the other location,
then use the @othermapset notation.
