[GRASS-dev] debugging nviz with TclTk 8.5 aqua

[Michael Barton]

Glynn,

After some delays, I managed to recompile GRASS 7 with CFLAGS="-arch  
i386 -g", etc so that gdb would produce useful output, and with TclTk  
8.5 aqua for Mac. Running nviz in gdb gives the results below.  
Hopefully these are more helpful. It freezes at the last line.


(gdb) run -f $GISBASE/etc/nviz2.2/scripts/nviz2.2_script  
elev=elevation.dem
