[GRASS-dev] NVIZ problem on Intel Macs

[William Kyngesburye]

That shouldn't be necessary - an Intel Mac has Intel builds of X11  
and OpenGL.

How did you build your Intel GRASS Lorenzo - on a PPC Mac with the  
Universal SDK?  Or on an Intel Mac?

I tried my build of GRASS CVS 5-27 (built on Intel).  NVIZ starts for  
me - I get the NVIZ Options/Output screen.  But when I select a  
raster and try to Run it, then it crashes, with nothing in the output  
window except the raster and the X icon to remove it, like so  
(sometimes the Please Wait window briefly appears):

Command: nviz
Path:    /usr/local/grass-6.1.cvs/bin/nviz
Parent:  wish8.4 [612]

Version: ??? (???)

PID:    648

Still looks like some OpenGL problem.  And, I get the exact same  
crash on my PowerBook, except that NVIZ processes the data a little -  
this appears in the output winodw below the raster names:

Loading Data
Update elev null mask
Loading Data
building color table

and the raster names item has an additional printer icon.


This is the first time I've run NVIZ, so I'm not sure what to expect,  
but certainly not a crash.
