[GRASS5] NVIZ under Solaris?

GRASS GIS GRASS GIS developer

Hi,
I'm posting to the list in case other folks share the same question. I'm
using the Solaris binary release for GRASS 5.0 beta 8, and would like to
incorporate NVIZ. Although the man page and the tcltkgrass module are
there, the program itself does not appear to be. Is there a compiled
version of NVIZ for Solaris floating around, or will I have to compile
myself?

Also, g.manual appears to be broken in this particular binary release (I
ended up stealing the appropriate executables from beta 7). I get the
following:
GRASS 5.0beta8 > g.manual g.list
sh: /proj/grass4.1/grass5.0/grass5.0beta_sol26/man/1/g.list: cannot
execute

Finally, I'd like to throw out some thoughts on 5.0. I've been using
GRASS for eight years, and just started teaching a class using 5.0. I'm
finding the whole null value issue to be a real hassle: some frequently
used commands do not work as expected with either nulls or zeroes,
depending on the command. Example: r.buffer doesn't treat zero as nulls
anymore (contrary to documentation), yet r.null doesn't work on
reclassed files, requiring two additional steps if you want to buffer
from a reclassed file. I'm seriously considering reverting to version
4.x, as the ease of use greatly surpasses the additional functionality
of version 5.0 for me. Will these issues be addressed in the "stable"
release, or are they inherent to the product? Thoughts, comments? If
you're replying to this part of the message only, I guess we should
change the subject :slight_smile:

Hi Malcolm, dear GRASS community,

Yesterday we could fix a bug when running NVIZ with tcl/tk8.3 libraries.
Due to the updated "configure" routine it should be possible to compile
the current GRASS5/CVS version on SUN including the NVIZ.
As I am just compiling it on SUN, I may be able to provide NVIZ binaries
the next days.

Also, g.manual appears to be broken in this particular binary release (I

following:

This should be fixed already. For you: To fix it easily, edit
$GISBASE/etc/GIS.sh
(if GIS.sh is not existing, it is $GISBASE/etc/Init.sh)
and add after line 2:

# set PAGER environment variable if not set
if [ ! "$PAGER" ]
then
        PAGER=more
        export PAGER
fi

Hope this helps. This bug only occurred in certain environments.

Malcolm, thanks for reporting this. The r.null problem is already
on the BUGS list, I have added the r.buffer problem.

Dear GRASS users: we need your bug reports!
Currently we are collecting all known in
  http://freegis.org/cgi-bin/viewcvs.cgi/~checkout~/grass/BUGS

The severe bugs are tagged as "release-critical" now. Means, if it
is not fixed, we can't publish GRASS 5.0stable. Like that you
can be sure to get a *stable* GRASS 5 release. The development team is
concentrating at time on fixing these critical bugs.

Please report all bugs you know with our bug report form:
  http://www.geog.uni-hannover.de/grass/bugtracking/bugreport.html

Note: If you are using an older version than GRASS 5 beta8, check the
NEWS file first:
  http://freegis.org/cgi-bin/viewcvs.cgi/~checkout~/grass/NEWS.html
if the bug is already fixed (this reduces mail traffic).

We encourage all users to report bugs in order to get a stable
GRASS GIS!

If you have suggestions to improve certain modules, concepts etc,
please send ot, too.

Thanks for your cooperation,

Markus Neteler
