[GRASS5] Re: Tcl8.4 support?

[Hamish]

An update along the lines of this thread:
http://article.gmane.org/gmane.comp.gis.grass.devel/2026
Debian has since updated TclTk.


Not much time to work on this right now, but just to note that a problem 
still exists. (although in a slightly different place?)



Running 5.0.3rc5's NVIZ on Debian/testing (Sarge) Oct27-2003 with TclTk 8.4.

with:
gcc 3.3.2 20031005 (Debian prerelease)
glibc 2.3.2-7
tcl, tk, tcl-dev, tk-dev: version 8.4.4-1
Linux 2.4.21 i686


both with & without the -lpthread fix.
 (the unmodified version now no longer locks up with TclTk 8.4.4)

Compiling with TclTk 8.3's includes and gcc 3.3.2 it works fine (wish=8.4).


GRASS 5.3-cvs, TclTk8.4 fails in the same way as above, ie "nviz -q" ok until
sliderbar or Panel->Surfaces->New; nviz elev=dem_raster flashes on before:
