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.
