[GRASS-dev] [bug #4768] (grass) nviz segfault on startup when creating display window

[William Kyngesburye]

Just for the heck of it, I tried today's CVS snapshot with an X11  
build on Mac OS X.  Uh, it's working now.

But wait, there's more - the X11 NVIZ also works on PPC AND Intel Mac  
OS X.  And since NVIZ and the wish used by the GUI are not related, I  
was able to start the X11 NVIZ from the gis.m gui in Tcl/Tk Aqua.   
NVIZ in X11 doesn't have the twitch in the browser like in Aqua, so I  
could add rasters and vectors after the initial startup.

I'm using the same Universal Tcl/Tk 8.4.13 X11 build of mine from  
June, as used in the bug report.  Basically, nothing's changed.   
Nothing new in the NVIZ or OGSF source (just the switches for X11/ 
Aqua/Win).

I did notice when I built it this time, the first run linked to  
Apple's Tcl/Tk libraries, not my X11 build like it was supposed to,  
and that gives the XQueryExtension crash.  I saw that my Tcl/Tk was  
missing the symlinks for libtcl.dylib/libtk.dylib to libtcl8.4.dylib/ 
libtk8.4.dylib, so -ltcl -ltk of course didn't find those to link to,  
and moved on to Apple's in /usr/lib!  After fixing that and  
rebuilding NVIZ, success.

So, Mac X11 working.  Now to figure out the Aqua side of things...
