What errors did you get?  If you got an error of the form

        cc -g  -I../../../../include -I/usr/local/include -I..  -o eucsyms eucsyms.o callbacks.o newthor.o dirdomcalls.o latdiffs.o arrays.o  filecalls.o Ooglcalls.o glgcalls.o -L/u/gcg/ngrap/lib/sgi  -lstubdraw -lgeom -lpolylist -lbbox -linst -llist -ltlist -lvect  -lmesh -lquad  -lgeom -lbbox -lstub -lshade -lcolor -l3d -loogl  -lforms -lfm_s  -lgl_s -lm 
/usr/bin/ld:
Can't locate file for: -lstubdraw
*** Error code 1
...

then it is due to a mistake that we just found in one of our
makefiles, namely in the file

	GEOMROOT/src/bin/eucsyms/O.sgi/Makefile

where GEOMROOT is the root of the geomview source tree.  There
is a line in that file that says

LDFLAGS = -L/u/gcg/ngrap/lib/sgi \

but should be changed to say

LDFLAGS = -L${GEOM}/lib/${MACHTYPE} \

if you make this change and type 'make depend' and then 'make all'
from the GEOMROOT directory things should work.

NOTE: the last character of the changed line should be the backslash
('\').  No trailing spaces.

Alternately you could re-ftp geomview.tar.Z which has now been fixed.

If you were having errors related to prototypes, then I don't know
what's wrong.  Please send the output of your "make" command to
software@geom.umn.edu and we'll figure it out.

Don't use gcc on the IRIS.  Geomview is supposed to work with plain cc.

Once you get geomview compiled you can take a look at the example
programs (hinge, nose, trigp, eucsyms, graffiti) to see how to
use it with another program.  If you give us an idea of what
you want to do we can provide some more pointers.
