I'm working on it..........

[that's the second hit for this bug with Slackware 9.0, for anyone 
keeping score. What gcc, glibc, tcl versions is that please?]

hmmmm.. that's in a different place to where it was breaking for me.
(Debian/Testing)

Is it a floating point or integer based map?
If it is an integer based map, try converting it to a FP with r.mapcalc,
  (r.mapcalc fpmap=origmap*1.0)
and see if that works. (doubtful)

Try compiling with -DDEBUG_MSG and see if that fixes it.
   (CFLAGS=-DDEBUG_MSG ./configure ...)
 [that worked here, I have no idea why]

Try compiling with gcc ~2.95 if you can & see if that fixes it.
 [that works here]

Which version of Tcl are you using? Does using 8.3 help?



please let me know if any of this works, or doesn't.



I've currently got my integer-map bug tracked down to this line on
src/libes/ogsf/GS2.c:  (line 1445)
   filename = G_fully_qualified_name(filename, mapset);

Next is to follow G_fully_qualified_name() in src/libes/gis/nme_in_mps.c.
Hopefully this leads somewhere.

You're getting past that into etc/nviz2.2/scripts/nviz2.2_script though.
tcl8.4?? Maybe try adding -lpthreads to the end of XTRA_LDFLAGS in
src.contrib/GMSL/NVIZ2.2/src/Gmakefile
and see what that does?


also of note, we have both:
/src.contrib/GMSL/NVIZ2.2/scripts/nviz2.2_script
and
/src.contrib/GMSL/NVIZ2.2/nviz2.2/scripts/nviz2.2

Which are almost the same thing. The first one is the real one.



oh, what fun,
