I've installed the grass6.0.2 binary onto a box using fedora core 5. I upgraded from core 3 in the hope that NVIZ might start working. After some time I got grass working after creating links relating to libssl and mysqlclient. The final problem relates to nviz. I had better success than under core 3 after i created links to libtcl & libtk. However...
* In 6.0.2 the initial dialog box appears. After entering a DEM to
display and depressing "run", a small information box flashes,
followed by a flash of another larger box. Other than the initial
dialog box, no other NVIZ boxes stay on screen
* In 6.0.0 a similar thing happens, but it happens slower and is
accompanied by an error message that reads something along the
lines of...
o *** glibc detected *** NVIZ: munmap_chunk(): invalid
pointer: 0x097fed78: ...then follows a multi page dump
I tried downloading the latest src code & compiling it, however i am very new to the linux environment and I had little success. I've been working on this all yesterday and today, and have finally admitted defeat. I would be grateful if someone could offer some help.
Many thanks
Ian

An unfortunate part of the GUI is that error messages tend to flash away
too quickly. Try starting from the GRASS> prompt. ("nviz -q") it still
won't work but at least you can see what the error message said.

If it is what I think it is, then it is a known bug, fixed recently.
Most likely you compiled with tcl/tk 8.4-dev? If you try ./configure and
"make" with tcl/tk 8.3-dev I think it should work. I don't know if FC5
has tcl/tk 8.3 packages anymore or if they just provide 8.4.

Getting that ready the first time is the hardest step. Anything you
figure out generally applies to other linux software too, so spending
time on this wasn't wasted time.
If you can download the lastest GRASS 6.1-cvs source code snapshot, it
should work for you with tcl/tk 8.4.
