Hi Markus,
Thanks for your help. I am trying to follow your instruction but ran
into a problem compiling v.buffer. I used svn to download grass 6.5 into
/usr/local/src and it appears to have compiled just fine and grass65
seems to be working. To compile v.buffer I tried:
sudo make MODULE_TOPDIR=/usr/local/grass-6.5.svn/
from the /usr/local/src/grass6_devel/vector/v.buffer directory but that
didn't work. I pasted the error message below.
I expect my MODULE_TOPDIR assignment is not correct. I'll try to figure
out the problem tomorrow but if you know what the problem is please let
me know.
Once I compile v.buffer do I have to do anything to deactivate v.buffer2?
Thanks again for the help.
Ned

Hi - I am trying to create buffers for large (~1GB) line and polygon vector
files. I tried v.buffer but after letting it run overnight with no apparent
progress I killed the process. I'm not aware of any software capable of
buffering large vector files on a modest computer so that wasn't a big
surprise.
So we hope that there is still a chance to make GRASS the only one
to suppor this :)
Note that v.buffer is somewhat in transition:

"All these test cases are successfully completed by v.buffer/v.parallel;
on confirmation by I would reactivate v.buffer/v.parallel and deactivate
v.buffer2/v.parallel. For trunk that would mean that v.buffer which is
actually v.buffer2 gets replaced with v.buffer, same for v.parallel.

If you can compile yourself, please try GRASS 6.5 from current SVN
(or weekly snapshot) and go into
vector/v.buffer/
and compile this fixed older but apparently better version.
If that then works ok for you, it will be another reason to reactivate
the fixed original version of v.buffer rather than promoting the
currently used v.buffer2.
