`what():  clGetPlatformIDs`
`Aborted (core dumped)`

Answer 1

Since I have not enough rep for a comment I put this as an answer.

What is the output of 'ldd clinfo'? This will tell us which libraries clinfo is using. You might have to search for the absolute path of the clinfo executable first.

Can you provide the content of the directory /etc/OpenCL/vendors/ . File names and content would be useful for a start.
