        I am having some problems getting collision detection to work
in a simulation that I am writing using Performer 1.2. Considering that
the faq and release notes warned that the pfuCollide functions are
jumpy I set out writing my own. After implementing simple terrain
following (just like pfuCollideGrnd returning zpr) I decided to test
out the pfu version. Here's the problem:

        When I compile my code that calls pfNodeTravMask, pfSegsIsectNode and
pfQueryHit everything goes nicely and I have great performance.

        When I try to use the pfuCollideGrnd function as a replacement
with all of the same links (including a link to libpfutil.a) and all of
the same includes (including #include "/usr/src/Performer/include/pfutil.h")
I get the following:

cc pfobj2.o vrnav.o pftri.o vr.o -o vr -xansi -D__STDC__ -I. -I..
-I/usr/src/Performer/include -I/usr/include/Performer /usr/lib/libpf.a
/usr/src/Performer/lib/libpfutil.a /usr/lib/libpr.a -lmpc -limage -lfm
-lgl_s -lX11 -lm -lfpe -lC

/usr/bin/ld:
Undefined:
pfNodeTravMask
pfMQueryHit
pfSegsIsectNode
pfQueryHit
*** Error code 1

Stop.

So almost identical versions of code are having problems finding functions
that should be easily found. This isn't the first time I have had a
problem with mysteriously undefined functions (just the most frustrating).
Obviously I have overlooked some small something, or we have installed
Performer incorrectly.

Any insight is greatly appreciated.
