Sdk problem with make

I did make to sdk folder and the problem is the -lcuda. What I must do?

try this:
bash$: locate libcuda
to make sure that you have it. Try these:

  1. put the path to libcuda in the LD_LIBRARY_PATH envi. var. Logoff and login again.
  2. If that does not work, put the path to libcuda in /etc/ld.so.conf. And run an ldconfig.

After do “locate libcuda” I took this:

/usr/lib/nvidia-current/libcuda.so

/usr/lib/nvidia-current/libcuda.so.1

/usr/lib/nvidia-current/libcuda.so.270.41.19

/usr/local/cuda/lib/libcudart.so

/usr/local/cuda/lib/libcudart.so.4

/usr/local/cuda/lib/libcudart.so.4.0.17
