[GRASSLIST:876] RE: GRASS on Mac OS X

[Bruce Bushby]

I know how you feel, also new to grass! From what I've read so far, try
the following (as I said I'm also new, so expect corrections from the list)
Also
I've never worked on a MAC, so not sure if any of this will make any sense.

First setup your user environment (the one that is running 'grass5'). Inside
$HOME, create a .grassrc5 file, this is parsed by Grass on startup, ie:
GISDBASE: /usr/local/grass5/gisdbase
LOCATION_NAME: london
MAPSET: wimbledon.london
GRASS_GUI: tcltk
MONITOR: x0

**I'm not sure about your monitor on a MAC, perhaps remove this line for
now.



Inside your users ".bash_profile" or equivalent environment file, export the
following:
export PATH=$PATH:/usr/local/grass5/bin:.
export GISRC=$HOME/.grassrc5
export GISBASE=/usr/local/grass5
export LOCATION=london
export GISDBASE=/usr/local/grass5/gisdbase
export LOCATION_NAME=london
export MAPSET=wimbledon.london



Create a very basic blank database directory tree, ie
/usr/local/grass5/gisdbase
/usr/local/grass5/gisdbase/london
/usr/local/grass5/gisdbase/london/PERMANENT
/usr/local/grass5/gisdbase/london/PERMANENT/LOCAL_WIND
/usr/local/grass5/gisdbase/london/wimbledon.london/
/usr/local/grass5/gisdbase/london/wimbledon.london/WIND

*probably should sit somewhere else, ie: /data/gisdbase

LOCAL_WIND and WIND should contain the following:
proj:
zone:
north:
south:
east:
west:
cols:
rows:
e-w resol:
n-s resol:


Provided you have not made any mistakes, you should be able to start Grass.
Remember your
region is not set, DEFAULT_WIND and WIND are empty templates. Try 'g.region
vect='grass vector map'
to set the region based on the map.

Use d.mon to start a monitor, then various commands depending on what format
your maps are in, for
example, using ESRI shape files:
v.in.shape input=yourmap.shp out=yourmap, then
v.support map=yourmap, then
s.in.dbf yourmap.dbf
s.in.shape in=yourmap.shp (Although this 'segmentation faults' on me?)
and something similar for rasta and other formats.

If you manage to display a rasta image of street maps, please tell me how.
I've been stuck
for 4 days now :)!

All the best

Subject: [GRASSLIST:873] GRASS on Mac OS X


I am a new GRASS user. I am having a number of difficulties using
GRASS 5.0.2 on Mac OS X 10.2.6 , using Apple's X11.

I can open existing locations, but cannot create a new location. I
get an error message

  /.cshrc: No such file or directory , which is repeated ten times and then
  Error in startup script: ERROR: LOCATION_NAME not set
     while executing
"exec g.gisenv get=GISDBASE"
     invoked from within
"set env(GISDBASE) [exec g.gisenv get=GISDBASE]"
     (file "/usr/local/grass5/bin/tcltkgrass" line 12)

I tried to work around this problem by creating folders and then
setting the region with the g.region command, but the g.region dialog
box is too large and execute button will not display on my 15 inch
monitor.

Any suggestions on how to solve either of these problems would be
appreciated.

Thanks, Gretchen Gallegos
