missing tesseract_opencl_profile_devices.dat (or how to disable OpenCL)

[Markus Leuthold]

I'm using tesseract-ocr built by OpenSuse TW. For each ocr run, an error appears about a missing profile file, then a new file tesseract_opencl_profile_devices.dat is created. The 2nd run with the profile file is then successful. How do I disable opencl at all (at run time, not at compile time) or fix the issue with the profile file?

[Zdenko Podobny]

There is no possibility to disable OpenCL at run time.

OpenCL is disabled by default and marked as experimental, not suggested by the forum/issue tracker, etc. 

It is there (as compile option) only as a startup point for possible developers.

It looks like OpenSuse TW builds the package with "--enable-opencl"

https://build.opensuse.org/package/view_file/openSUSE:Factory/tesseract-ocr/tesseract-ocr.spec

Would you consider this a bad choice and prefer to build without opencl for a large distribution such as OpenSuse?

[Zdenko Podobny]

It is incompetent and irresponsible to use an experimental code in production/distribution.
