Reference: http://stackoverflow.com/questions/7542808/what-is-needed-to-compile-opencl-on-ubuntu-and-by-extension-opencl-period

First of all, CUDA library did not provide the needed cl.hpp or (maybe cl2.hpp) file. So, need to download them from
https://www.khronos.org/registry/cl/

I picked the OpenCL 1.2 cl.hpp file

and put them into /garlic/apps/cuda7.0/include/CL and set C_INCLUDE_PATH and CPLUS_INCLUDE_PATH

export CPLUS_INCLUDE_PATH=-I/garlic/apps/cuda7.0/include
export C_INCLUDE_PATH=-I/garlic/apps/cuda7.0/include



export CC=gcc-4.9.3
export CXX=g++-4.9.3
export CFLAGS='-I/garlic/apps/cuda7.0/include -L/garlic/apps/cuda7.0/lib64 -lOpenCL -Wl,-rpath -Wl,LIBDIR'
export CXXFLAGS='-I/garlic/apps/cuda7.0/include -L/garlic/apps/cuda7.0/lib64 -lOpenCL -Wl,-rpath -Wl,LIBDIR'

./configure  --prefix=/garlic/apps/BUDE-1.2.1-CUDA_CL --enable-opencl

make
sudo make install

Ran into errors:

Fatal error with compile_bude

=============================================

I managed to get the source code compiled with CUDA by commenting out those undeclared cases in ocl/oclPrintError.cpp that makes reference to those Macros. There were a couple of errors due to a typo in the header file path in main cpp files in sequence and bild folders

#include "../../lib/constants/errorNumbers.hpp"
should be
#include "../../../lib/constants/errorNumbers.hpp"

=========================================================
Alternatively,  install Intel's OpenCL SDK: intel_sdk_for_ocl_applications_xe_2013_r2_sdk_3.1.1.11385_x64.tgz

Inside it has these rpms

opencl-1.2-base-3.1.1.11385-1.x86_64.rpm
opencl-1.2-intel-cpu-3.1.1.11385-1.x86_64.rpm
opencl-1.2-devel-3.1.1.11385-1.x86_64.rpm
opencl-1.2-intel-devel-3.1.1.11385-1.x86_64.rpm

That is all you need to get the Intel OpenCL thing

You will need the Nvidia drivers and the nvidia-compute package but the Intel's package has the latest OpenCL stuff. What it is happening is that those Macros are not define in the Nvidia packages. Nvidia stop supporting OpenCL on version 1.0 or 1.1.
