Hi Hamish. Thanks for the help.
g.version -r returns 6.4.3
echo $GISBASE returns /usr/local/grass-6.4.3
echo $GRASS_LD_LIBRARY_PATH returns /usr/local/grass-6.4.3/lib
echo $LD_LIBRARY_PATH returns /usr/local/grass-6.4.3/lib
All good so far. However,
ls $GISBASE/lib shows no libgrass_gmath
I compiled 6.4.3 from source (can't remember specifically why). I run
6.4.2 on my machine at work and it's fine. It's odd that the error
message specifically complains about 6.4.2 even when everything points
The v.dissolve script seems to run fine until it calls v.extract. I've
had a quick look at the source code, but I'm not so good at C. I ran
make in the lib directory with only a couple of warnings and I don't see
anything really problematic.
Worst case scenario is I could go back to 6.4.2. 7.0 doesn't come close
to compiling on this machine at present.
