title: PhysX Linker Problem on 64-bit Ubuntu
body: <p>I am having a problem getting my project to link with the PhysX libraries on my 64-bit machine.  It compiles perfectly fine.  I've used the exact same settings as on my 32-bit machine (with the exception of some debugging flags), which links perfectly fine.  Here is the build output:</p>
  <blockquote>
  <p>g++ -L/usr/lib/PhysX/v2.8.1 -L/usr/lib -o&quot;PhysXTest&quot;  ./main.o   -lPhysXLoader -lglut</p>
  <p>/usr/bin/ld: skipping incompatible /usr/lib/libPhysXLoader.so when searching for -lPhysXLoader</p>
  <p>/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.2.3/../../../../lib/libPhysXLoader.so when searching for -lPhysXLoader</p>

  <p>/usr/bin/ld: skipping incompatible /usr/lib/libPhysXLoader.so when searching for -lPhysXLoader</p>
  <p>/usr/bin/ld: cannot find -lPhysXLoader</p>

  <p>Also, if it's of any consequence, I have already set up symbolic links to usr/lib.  Does anyone know what's going on?  Please let me know if you need any more detail.  As always, thanks in advance.</p>
