Dear Eric,
Since your rasters work in 5.3 there clearly isn't a problem with DOS
format files: my guess was wrong. (Incidentally, zip/unzip are different
from gzip/gunzip. They are available >in Ubuntu.)
I would avoid using GRASS 6.1.cvs unless it is important to you to have
some feature not available in a stable release. I am amazed how many GRASS
users seem to use the >development version which is much more likely to
contain bugs. Can you manage with 6.0.1?
Chris
PS If you want to send me a tar or zip file of some of your maps I can
check they load with 6.0.1.
Chris and Others,
I've racked my brain trying as many things I could think of. Here's some
more tests I've done:
1) I've tarred the Cygwin 6.1 Grass Location and transferred it to my Linux
partition by: a) gftp from within Ubuntu (binary mode transfer) b)
drag-and-drop using Nautilus c) the cp and mv commands from the command line
d) transferring first to my FAT32 data-swap partition then to Linux
partition. In all cases, rasters do not display; various r* commands give
seg faults. ps -aef shows one "d.mon <defunct> process for every raster I
attempted to display.
2) I've tarred the Location using the --posix switch in tar, thinking
perhaps posix-compliance was an issue (?). Regardless, same effects seen in
(1) above. Also tried passing the -a switch in gzip on the tarfile, then
decompressing and untarring into Ubuntu. No difference.
3) Tarring individual rasters in Cygwin (i.e., tar cvf rastername.tar
*/rastername from within the PERMANENT directory) and then un-tarring them
within a new Location in Ubuntu results in same as (1) above.
4) Tarring an individual 6.1 Cygwin raster and untarring into a pre-existing
Grass 5.3 location on RedHat 8 is successful; raster can be displayed and
behaves normally.
Very frustrating. I've tarred and gzipped a test Location and placed it on
my ftp site ftp://gsca.nrcan.gc.ca/outgoing/Patton for anyone who wants to
try it out on their Linux distro and see if they can reproduce my errors.
It's a representative mix of a few rasters and vectors that I've been
working with. Size is 30MB compressed, 100MB uncompressed. I can cull that
down if it's too big.
Thanks,
~ Eric.
