#522: NVIZ fails to start

Comment (by ewcgrass):

 All current versions of grass were compiled and installed after doing a
 clean upgrade from FC5 to Fedora-10 (i.e. drive partition with grass
 installation directories were reformatted). I'm thinking that if it's
 tcl/tk related, then the relative change in redraw time for the lower part
 of the GIS-manager that I noticed after the tk upgrade leads me to believe
 the bug-fix upgrade from tk-8.5.3-4 to tk-8.5.3-5 may have broken things
 ... might this be so? The trouble is, I don't recall needing to run NVIZ
 after upgrading to Fedora 10 but before tk-8.5.3-5, so I have nothing to
 compare to other than what I'm used to running FC-5.

 I just now reinstalled grass-6.3.0 using yum and ran my files and also
 spearfish elevation.dem, both with same disappointing results.

 The following is the error message I get when trying to run NVIZ from gui
 from drop-down menu in grass-6.4.0-RC3 and spearfish elevation.dem.

 Loading raster map <elevation.dem at PERMANENT>...

 Loading raster map <elevation.dem at PERMANENT>...

 Error in startup script: could not create rendering context
     while executing
 "togl $Nv_(TOP).canvas -rgba true -double true -depth true"
     (procedure "Nv_makeGUI" line 56)
     invoked from within
 "Nv_makeGUI $Nv_(AREA)"
     (file "/usr/local/grass-6.4.0RC3/etc/nviz2.2/scripts/nviz2.2_script"
 line 1052)

 I don't expect that I should have to recompile grass 6.2.0, 6.2.3 and
 6.4.0-RC3 after doing a minor upgrade from tk-8.5.3-4 to tk-8.5.3-5, but I
 guess one never knows for sure without trying. I need to leave for a
 couple of hours but when I return (and checking here first), I will
 remove, compile, and reinstall all versions of grass and report my
 findings using both my files and spearfish.
