I've added the clinfo output in the attachment.
I think I've tracked it down to being unable to link rt with OpenCL
library. While running "svn co svn://
svn.code.sf.net/p/brlcad/code/brlcad/trunk/ brlcad" as mentioned here
<https://brlcad.org/wiki/Compiling>, it gave the following error:
svn: E170013: Unable to connect to a repository at URL 'svn://
svn.code.sf.net/p/brlcad/code/brlcad/trunk'
svn: E000111: Error running context: Connection refused
