[GRASSLIST:3575] Re: NVIZ in 5.7

[Gerry James]

Thanks for the input Michael.  I have tried running it quietly (nviz -q) in
both 5.3 and 5.7 and get the same sort of error...Are you aware of any
problems with the NVWISH2.2 executable. I am not sure but it looks like it
is originating from there...Also in some of my reading it appears that there
may be some problem with running it with Tcl/tk 8.4.  That is what we are
running for a number of applications...

  Gerry,

  I believe you've hit a known bug in GRASS 5.7. NVIZ won't start from the
GUI g.parser interface you get when you run it from the command line, nor
will it accept front loaded elevation data (or any other data). The only way
it will run is to start 'quietly' without loading data up front.

  nviz -q

  Then load the data once NVIZ has started.

    I am trying to run NVIZ in 5.7 and I keep getting the same error.  I
have tried to run it from the command line while loading the elevation.dem
data that comes with the sample data and get the following lines

    Loading Data

        invoked from within
    "if {$argv == ""} {

        (file "/usr/local/grass57-29_05_2004/bin/nviz" line 16)

    I have tried copying the nviz2.2_script into a number of different areas
with no luck.

    Can anyone help me out.

    Cheers
