This one is a bit odd...I've transferred several tarred/zipped Grass
projects from a LaCie external hard disk (formatted NTFS) onto a Linux
patition of a dual-boot XP/Breezy PC. The projects in question reside on
/home/epatton/Projects. I've enabled full 777 privileges, recursively.
Grass
loads the project up fine with no obvious system errors. I can
display/pan/zoom any vectors, even vectors that have been converted from
5.4
to 6.1 format using v.convert(.all).
However, no rasters will display. I've tried several rasters from different
locations, to no avail, even after setting the region with g.region
rast=Rastername. These rasters display fine on a Cygwin Grass session; in
fact, they were created from a Cygwin Grass installation.
Sorry to answer my own post, but I've got some additional information that
might help:
- r.compress reports that '3.0 compression indicated'. Typing r.compress -u
gives a segmentation fault.
- r.stats, r.univar, r.describe crash with 'Segmentation fault'; no other
error messages are given.
- I can run g.region rast=rastername no problem; r.info gives a standard
information screen with nothing out of the ordinary; rows and columns,
resolution, projection, all look good.
- r.report gives the following:
r.stats: sh: line 1: 10646 Segmentation fault r.stats -acr fs=:
'input=DumpsiteA_MB_1m.fill.shade.comb@PERMANENT' >/home/
epatton/Projects/Miramichi/PERMANENT/.tmp/w5-dar-epatton/10644.0
Once again, I've checked that all permissions are write-enabled for the
entire Location.

My first guess would be that the files were corrupted in transfer,
e.g. by transferring them as text files (CRLF->LF translation).
Do the sizes of the files in the cell/fcell directories match when
viewed under both Windows and Linux?

I didn't read all the mails but there was a bug in r.stats which we
fixed in November - maybe your version is too old? A couple of
commands depend on r.stats.
