Symbolic linking confusion

[Bruce Labitt]

Just to add to the top posting madness :P

Derek was right.  Adding the -L/usr/lib/nvidia-current-updates to the 
make file did it.

The symbolic linking was a red herring.

For anyone who is interested, the makefile in question was
NVIDIA_GPU_Computing_SDK/C/common/common.mk

The fix was to change line 144 from
LINK     +=

to
LINK    += -L/usr/lib/nvidia-current-updates

Ubuntu 12.10, 3.5.0-27-generic x86_64
nvidia-cuda-toolkit installed


Thanks!  Now running CUDA demos...
