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
to 6.4.3.
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.
Thanks, Dave

v.extract: error while loading shared libraries:

However
ls -l /usr/local/grass-6.4.2/lib
shows
-rwxr-xr-x. 1 root root 77615 Dec 21 2012 libgrass_gmath.6.4.2.so
lrwxrwxrwx. 1 root root 23 Dec 21 2012 libgrass_gmath.so ->
libgrass_gmath.6.4.2.so
just as I would expect, with read and execute permissions.
Oddly, I'm running GRASS 6.4.3, but all the libraries are 6.4.2. This
is on Scientific Linux 6 (derived from RedHat Enterprise linux 6).
Hi,
try:
GRASS> g.version -r
:)
GRASS> echo $GISBASE
GRASS> echo $GRASS_LD_LIBRARY_PATH
GRASS> ls $GISBASE/lib
GRASS> echo $LD_LIBRARY_PATH
that should show you where the grass install is located.
It's usually fine to have many versions of GRASS installed
at the same time, they can all run self-contained.
--> you might check if the 6.4.2 install is listed in /etc/ld.so.conf
or /etc/ld.so.conf.d/*, if so change it to the location of the 6.4.3
libraries and re-run `ldconfig` (as root).
good luck,
Hamish
