New issue 1325 by vungoctr...@gmail.com: Error when running tesseract 3.04
with --enable-opencl option
https://code.google.com/p/tesseract-ocr/issues/detail?id=1325

What steps will reproduce the problem?
1.Install NVIDIA OpenCL SDK
(http://developer.download.nvidia.com/compute/cuda/6_5/rel/installers/cuda_6.5.14_linux_64.run)
2. Install leptonica 1.71 then install tesseract with below command:
./autogen.sh
configure --enable-opencl
sudo make -j install LANGS=
3. Run tesseract with any picture

What is the expected output? What do you see instead?
Expected: tesseract should run normally
Result: Error log comes as below:

I am not opencl expert, but you wrote that you use NVIDIA OpenCL SDK, but
your OpenCL info shows you have no nvidia device. Did you try to use Intel
OpenCL SDK[1]?

Both Nvidia and Intel SDK are not working with my system.
But AMD APP SDK[1] can work fine with Open CL option.
