RE: Help, zillions of undefined references

[lrtaylor at micron dot com]

It looks like you're actually using GCC 2.96 (since your command is
g++296).  Try changing CC and CXX in your Makefile to be gcc and g++,
respectively.  That should get you using the right compiler that came
with the system.  You're probably actually just using a version of GCC
added to the system for backward compatibility.

Cheers,
Lyle

OK, here it is:
/usr/bin/g++296 -o tsnake -g       -L/usr/local/tsnake_new/lib
-L/usr/X11R6/lib
  main.o xwindow.o make_pulldown.o  snaxel.o 
contour.o               tsnake.o dymprog.o io.o image.o lmesqCC.o 
fileDialogs.o InterestingArea.o              parameterDialogs.o 
minimization.o bSpline.o cutting.o   liblimin.a   -ltiff  -lm -lXm -lXt
-lX11

If anybody has any ideas about how I should proceed to try to eliminate
all 
these undefined references, I'd appreciate hearing them.  Thanks very
much.
