Dear all,
Thank you very much for the help. In the end, my problem was more
basic than Augustin's suggestion. Starting R from within GRASS was
basically all I needed to do. Also, Roger, thank you for the
'pre-emptive' help with your comment about setting 'plugin=FALSE':
sure enough, when I tried without that command, I got the following
and R exited:
x<-readRAST6("GLC2000_Landcover_SEAsia")
ERROR: Incompatible library version for module. You need to rebuild GRASS
or untangle multiple installations.
But it worked fine with plugin=FALSE.
AFAIK this indicates in this case that the GRASS-GDAL plugin is out of sync
with GRASS. Rebuilding the plugin should help.
Background:
- first compile GDAL without GRASS support
- then compile GRASS (needs GDAL)
- then compile the GRASS-GDAL plugin (needs GDAL and GRASS)
- use R
Markus,
The plugin is great for those who build from source, but here Tim is using
the Kyngchaos OSX binaries, and seems to have a working system. It may be
that some plugin directory is hanging around from a failed install, but
for relatively many otherwise able users, this is too hard to fix. We've
seen numerous Debian/Ubuntu users with similar version mismatches, and
they aren't easy to settle - I get tripped up by the plugin myself when
updating GDAL or GRASS. So for people who find that it helps, not using
the plugin provides a solution avoiding building from source.
Best wishes,
Roger
Hope this helps,
Markus
