[GRASS-user] libgrass_gmath

[Dave Roberts]

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
