After tweaking the Makefile to use the right compiler and flags, and point
to glut running make gives:
g++ -I/usr/X11R6/include -O2 -g -DSAFETY -DIOSTREAMH -c terra.cc
In file included from Geom.h:24,
from Heap.h:4,
from GreedyInsert.h:4,

Slackware Linux current, which uses gcc 3.2.3. Is that the source of the
problem?

AIUI this is just a script which drives terra though, not a standalone
solution?

Are these sensible values, or should we be pushing maxnodes up, and
maxerror down (and if so, how far) - I'm guessing that fitting a better
surface will take longer, I'm not particularly worried about this, as long
as we get a good result for the finished scenery - also more points=more
triangles, and we need to ensure we have scenery that's going to be usable
on a wide range of hardware.
