Dear Sandra, okay, good, having a working clinfo is a good step. :-) The cmake line looks fine, also the PATH and LD_LIBRARY_PATH export are fine. Having OpenCL installed in a different home directory sounds a bit suspicious, though. Is the user account running ViennaCL the same as the user account running clinfo? (Note: We ran quite a number of benchmarks on an ODROID-XU3; however, I recall that there were a few obstacles in the system setup that we had to sort out.)
