I can not reproduce it. Error does not looks like related to OpenCL.

Do you have installed more version of tesseract library? It looks like you are 
mixing different tesseract version (You wrote "download latest source files 
available in project's Drive folder", but there is just version 3.03-rc1 
version. But your output states you try to run 3.04.00 version...).

Did you tried to remove them before install 3.04 opencl version?

Yes, I made a cleanup and I have no more errors.
