Bandon,

Try William Kyngesburye's most recent Mac builds (this week) if you can. I
don't know if this is a Mac issue or not. I'm copying it to the developer
list in case it is a bug that needs to be reported.

You can also try a script I did sometime back before v.overlay recognized
attribute tables. It's called v.append and you can get it from my website
<http://www.public.asu.edu/~cmbarton/files/grass_scripts/&gt;

It uses GDAL to merge the 2 vectors. You can take a look at the GDAL
commands in the script and do it manually and get more flexibility .

Hey again everybody...I didn't receive any feedback, so I'll try this again.
Thanks!

Subject: combining vector maps on Intel Mac OSX using X11
      To: grassuser@grass.itc.it

Hey Fellow GRASSers:

I am trying to combine vector maps (two at a time) using v.overlay, and I also
want their full attribute tables merged.

The problem is, GRASS shuts down when I run the command. The x11
command window
tells me that a Bus error closed the GIS manager.

I end up with an output map with the name of the new vector I attempted to
create, but the data are missing for the merged locales.

I am running a nearly-most-recent cvs (within 2 weeks, cannot connect
my Mac to
the internet currently due to the lack of a place to do so....), and I run
GRASS fully within X11 (the display manager is afster than running on the
native mac). The vectors I am trying to combine are polygons of archaeological
sites, with attribute tables that contain the same exact field names (i.e.,
site number, affiliation, type, etc etc).

Any suggestions?

Thanks,
Brandon
