OpenCL only works as root

Question

No matter how I try to get OpenCL working (sgminer, cgminer, c programming examples, clinfo)

I only get a result when I run as root.

When I run clinfo not as root I get:

terminate called after throwing an instance of 'cl::Error'
what():  clGetPlatformIDs
Aborted (core dumped)

I am using the AMD opencl implementation, and the correct ICD file does exist under /etc/OpenCL/vendors. I have changing the permissions of various files with no success.

How can I get this to work without root access

Were you able to solve this problem? I'm having a similar one, I would like to know if you could solve it. — silgon, Nov 26 '15 at 19:26
@silgon, it was quite a while ago, and subsequently I stopped working on OpenCL - I don't recall if I got it working as non root. — Zack Newsham, Nov 26 '15 at 20:43

This didn't help me. Still `terminate called after throwing an instance of 'cl::Error' what(): clGetPlatformIDs Aborted (core dumped)` – Eugene Gr. Philippov Oct 20 '21 at 06:29

Follow steps 9-11 of this answer

Optional: make symbolic links for desired system installed platforms: $ ln -s /etc/OpenCL/vendors/nvidia.icd /local/install/path/etc/vendors/nvidia.icd

export OPENCL_VENDOR_PATH=/local/install/path/etc/vendors

export LD_LIBRARY_PATH=/local/install/path/lib/x86_64:$LD_LIBRARY_PATH

Doesn't work under Ubuntu 18.04.x. The same error message `terminate called after throwing an instance of 'cl::Error' what(): clGetPlatformIDs Aborted (core dumped)`. – Eugene Gr. Philippov Oct 20 '21 at 06:39

ubuntu 14.04

same errormessage. GPU not recognised.

symptom-no files in /etc/OpenCL/vendors

create files by

sudo gedit /etc/OpenCL/vendors/amdocl64.icd

enter/paste libamdocl64.so

save

sudo gedit /etc/OpenCL/vendors/amdocl32.icd

enter/paste libamdocl32.so

save

sudo gedit /etc/OpenCL/vendors/inteocl.icd

enter/paste libintelocl.so

save

sudo gedit /etc/OpenCL/vendors/nvidia.icd

enter/paste libcuda.so

save

This worked for me. I did a lot of other things also- symlinc and xhost- but they did not fix the problem finally.
