Hi @Saikatsaha1996
In my device already available OpenCL 2.0 But when I run some OpenCL related applications i got error Like failed to load OpenCL runtime && libOpenCL.so not found
You may need to update LD_LIBRARY_PATH to point it to the folder where libOpenCL.so is located. Do you know where in your system this file is?
You could also try running clinfo to make sure you platform supports OpenCL and it's fully functional.
If clinfo isn't installed on your system you may need to build it from the sources: https://github.com/Oblomov/clinfo
The output should look like this:

Hi @Saikatsaha1996
Could you please try this?
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/system/vendor/lib64/
./minerd
