You should be able to see in your Notify output, it's clear that OSG isn't
including your OSG bin directory in its search path. If I recall from your OP,
that path is something like:
ThirdParty/Linux.x86_64.gcc4.4/OpenSceneGraph-2.8.3/bin
If this directory is not in your PATH, then it's odd that *any* OSG executables
even run, such as osgversion. You should add it, of course, as you would add any
package's binary directory to your PATH. (This is *nix 101, and not specific to
OSG.)
If that directory is already in your PATH, then it's mysterious that OSG doesn't
include it in its search. You could set a breakpoint in osgDB::findLibraryFile
to see why it's missing this directory, or just look at the source.

I believe you have a version problem on your hand. Do you have multiple

It is true that I've tried multiple versions of OSG. I began by building 2.8.3
from source myself. After getting these errors I decided to try 2.9.9 which was
built by a friend and seems to work for him.
I mistakenly posted the output from when I was using OSG 2.9.9 despite saying I
was using OSG 2.8.3, sorry about that. I try to make sure to never mix OSG
versions. When I decide to use 2.9.9 I make sure to move OSG 2.8.3 to another
directory, update my CMake to link against 2.9.9, completely rebuild my
baseline, and make sure LD_LIBRARY_PATH only points to the 2.9.9 lib directory.
To ensure that I'm not mixing versions I went through those steps to ensure I'm
using 2.9.9. When I ran my application before adding the OSG 2.9.9 lib
directory to LD_LIBRARY_PATH I got the following output...

Bottom line is that when you have multiple versions of OSG installed, you need
to manage your PATH and LD_LIBRARY_PATH very carefully.
I'm not entirely sure what you mean by having "OSG installed". So just to be
clear I do not have OSG installed in any system level folders such as /usr/lib or
/usr/local/lib...instead the OSG binaries/headers are just in a local folder that I've
told CMake about. Hopefully that isn't a problem?
I will continue to make sure that LD_LIBRARY_PATH only points to the version of
OSG that my code was built against. However, I haven't modified PATH at all,
should I be?
Thanks again for everybody's help, I really appreciate it.[/code]
