Symbolic linking confusion

[Bruce Labitt]

Recently been playing with GPU computing.  I'm running Ubuntu 12.10 and 
installed the nvidia-cuda-toolkit package.  It seems that the libs are 
in odd places.  Why does it matter?  Because I'd like to build the GPU 
Computing SDK.  So I follow the instructions in 
/usr/share/nvidia-cuda-toolkit,  down load the SDK and type make.

So it gets part way through and barfs because it can't find libcuda.

make[1]: Entering directory 
`/home/bruce/NVIDIA_GPU_Computing_SDK/C/src/deviceQuery'
/usr/bin/ld: error: cannot find -lcuda

No problem, just edit ld.so.conf.d/cuda.conf add the locations, 
ldconfig, and should be good to go.  Still can't find libcuda.  Must be 
a link issue...

$ locate libcuda
/usr/lib/nvidia-current-updates/libcuda.so
/usr/lib/nvidia-current-updates/libcuda.so.1
/usr/lib/nvidia-current-updates/libcuda.so.304.88

$ sudo ldconfig -v
...
/usr/lib/nvidia-current-updates:
     libcuda.so.1 -> libcuda.so.304.88
     libnvidia-tls.so.304.88 -> libnvidia-tls.so.304.88
     libnvcuvid.so.1 -> libnvcuvid.so.304.88
     libOpenCL.so.1 -> libOpenCL.so.1.0.0
     libnvidia-cfg.so.1 -> libnvidia-cfg.so.304.88
     libnvidia-ml.so.1 -> libnvidia-ml.so.304.88
     libnvidia-opencl.so.1 -> libnvidia-opencl.so.304.88
     libnvidia-glcore.so.304.88 -> libnvidia-glcore.so.304.88
     libnvidia-wfb.so.1 -> libnvidia-wfb.so.304.88
     libXvMCNVIDIA_dynamic.so.1 -> libXvMCNVIDIA.so.304.88
     libGL.so.1 -> libGL.so.304.88
     libnvidia-compiler.so.304.88 -> libnvidia-compiler.so.304.88

So do I just do
$ sudo ln -s libcuda.so.1 libcuda.so  ?  or the other way around ?

man ln is not very clear...

ln -s {target-filename} {symbolic-filename}

Which is really the target?  libcuda.so.1 ?  Did I get that right?

TIA,
Bruce
