Answer 1

I've recently used similar process on a clean build on linux, setting up OpenCL with an NVIDIA card.

Steps I took:

1 - install the NVIDIA driver.

2 - install the CUDA tool kit - (follwing the steps in the guide, there are many ways to do it, but I used the .deb installer, guide can be found here: http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/)

3 - using apt-get install the OpenCL headers. Command: sudo apt-get install opencl-headers

Using the : CL/opencl.h header I was able to compile C/C++ code using gcc/g++ and the flag: -lOpenCL

Explaination of steps

1 - Self explanatory

2 - The CUDA toolkit also installs the OpenCL library (libOpencl.so) but not the header (at least not on my system)

3 - hence the header can be installed with apt-get. The header files get stored in the /usr/include/CL directory
