[GRASS-user] problem setting region in 6.4 rc3

Hello,

Further on this. I tried creating a new location and mapset to see if there were differences in the projection parameters or if something was screwy. On startup, it gives an error I hadn't noticed before,

Warning: TclTk Aqua 8.4 unsupported

Here's the output:

'/Applications/GRASS-6.4.app/Contents/MacOS/grass.sh'; exit

Warning: TclTk Aqua 8.4 unsupported

Starting GRASS ...

-- here I created the new location and mapset, UTM Zone 35, entering the parameters by hand. After apparently successfullly creating the new mapset, GRASS failed with

TkMacOSXDoHLEvent failed : cppe 1 ,kHighLevelEvent 61657674 0000 tvea,-1708

and the Wish Shell hung, unresponsive. Killed the process, and restarted grass in the newly-created location and mapset; ran g.region -p, and got the same error:

region for current mapset <projection field missing>
run "g.region"

Does anyone have any ideas what is wrong, or what I could do to troubleshoot?

Many thanks,

Nick Cahill

Hello,

I'm using William Kyngesburye's OSX binaries of Grass 6.4 rc3, and find it doesn't work with my existing mapsets. On displaying a vector map, it gives an error "Error setting region: child process exited abnormally." If I set or display the region with g.region or g.region -p, I get the error "region for current mapset <projection field missing> xx run "g.region" The mapset is UTM zone 35, and works fine in 6.3. I installed the newest GDAL framework (1.6.0-5). I had thought the projection information was in one or more of the files in the mapset PROJ_INFO, etc., which are (for one typical mapset):

DEFAULT_WIND:

proj: 1
zone: 35
north: 1
south: 0
east: 1
west: 0
cols: 1
rows: 1
e-w resol: 1
n-s resol: 1
top: 1
bottom: 0
cols3: 1
rows3: 1
depths: 1
e-w resol3: 1
n-s resol3: 1
t-b resol: 1

PROJ_INFO:

name: UTM
datum: wgs84
towgs84: 0.000,0.000,0.000
proj: utm
ellps: wgs84
a: 6378137.0000000000
es: 0.0066943800
f: 298.2572235630
zone: 35

PROJ_UNITS
unit: meter
units: meters
meters: 1.0

WIND
proj: 1
zone: 35
north: 44865376.2790889
south: 4026393.07584904
east: 12546112.5351774
west: -1477754.5340503
cols: 184585
rows: 442103
e-w resol: 75.97511753
n-s resol: 92.37436345
top: 1759.33
bottom: 0
cols3: 184585
rows3: 442103
depths: 1759
e-w resol3: 75.97511753
n-s resol3: 92.37436345
t-b resol: 1.00018487'

I'm not sure why the default window sets it to one row and one column, but it works OK in 6.3. Any idea what's wrong here?

Many thanks,

Nick Cahill

Do you have TclTk 8.5 Aqua installed? Is it the ActiveTcl binary, another binary, or did you build from source?

That's just a warning, I don't disable TclTk 8.4 Aqua in GRASS (I'm not sure if I can). So it will still try to use it, which does not appear to work for defining a location.

So, the location setup was done in the GUI location setup tool? (which would have been running TclTk 8.4 Aqua)

region for current mapset <projection field missing>
run "g.region"

Did you try running g.region right in the Terminal? Save the current region, which seems to be OK:

   g.region -s

That was the problem - it was using TclTk 8.4 instead of 8.5. On deleting 8.4, it works perfectly. Thank you!
