Actually, now that I am thinking about it, this may be related to an ongoing NVIZ problem that I have had since moving to Ubuntu 11.03. Essentially, what happens is that NVIZ only <i>sort of</i> works in that I can get it to load up and display a map, but as soon as i touch any of the controls with the mouse, the map canvas goes blank. I can see glimpses of the map in coarse mode as if I rotate the view or zoom perspective or raise the height, but the display always goes back blank as soon as I stop moving. Sometimes the display DOES come back if I briefly click the eye arrow and then don't move the mouse, but this is only temporary. This happens on all three versions of grass I have installed (6.4.1 from ubuntu GIS repository, 6.4.2 from SVN snapshot binary, and 7.0 compiled from source). This is *not* the same exact issue with the 3D map display in 7.0, which just doesn't even load through, but it *is* an error I have been having with 3D display of maps in GRASS in general...<br>

Hi all,<br><br> After some time I've decided to start testing latest devel versions of GRASS on Ubuntu again. I have just today successfully compiled this week's SVN snapshot on Ubuntu 11.04 64-bit with the following configuration options: <code>CFLAGS="-g -Wall" ./configure --with-cxx --with-freetype=yes
--with-postgres=no --with-sqlite=yes
--with-tcltk-includes=/usr/include/tcl8.5
--with-freetype-includes=/usr/include/freetype2
--with-python=/usr/bin/python-config --with-wxwidgets=yes --with-nls
--enable-largefile --with-proj-share=/usr/share/proj --enable-64bit
--with-libs=/usr/lib64 --with-gdal=/usr/bin/gdal-config</code><br><br>There was one error upon compile in the NVIS directory where StdCmap.h was not found. It was because <code><span>libxmu-dev</span></code> was not installed. Apparently libxmu is a necessary component for NVIS to compile, but it is strangely not listed as a necessary component on the requirements page (<a href="http://grass.osgeo.org/grass70/source/snapshot/REQUIREMENTS.html" target="_blank">http://grass.osgeo.org/grass70/source/snapshot/REQUIREMENTS.html</a>). Anyhow, after I installed <code><span>libxmu-dev</span></code> then GRASS 7 compiles with no errors.<br>
<br>So far, most basic functionality seems to work, except for the 3-D view in the map display. I get the following errors when I try to use it:<br><br><span style="font-family:courier new,monospace">Starting 3D view mode... </span><br style="font-family:courier new,monospace">

Is this a known issue? Or something ubuntu-specific? It looks like an error with a specific variable that's being called in a python script before it is assigned. Any ideas on what to tinker with to get it working?<br>
