[GRASS-dev] GRASS 7 compiled from source on Ubuntu 11.04, error with 3-D view.

[Isaac Ullah]

Hi all,

  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: 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

There was one error upon compile in the NVIS directory where StdCmap.h was
not found. It was because libxmu-dev 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 (
http://grass.osgeo.org/grass70/source/snapshot/REQUIREMENTS.html). Anyhow,
after I installed libxmu-dev then GRASS 7 compiles with no errors.

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:

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?
