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.)
Best regards,
Karli

Could it be a problem that OpenCL is installed in another user's home? I
exported the PATH and LD_LIBRARY_PATH variables accordingly, but still
got the same error.
These are the steps I followed to compile ViennaCL:
/2032 cmake -DOPENCLROOT=/home/badia/opencl/Mali_OpenCL_SDK_v1.1.0/
-DOPENCL_LIBRARY=/home/badia/opencl/Mali_OpenCL_SDK_v1.1.0/lib/libOpenCL.so
ENABLE_UBLAS .
2033 make
2034 ls
2035 cd examples/tutorial/
2036 ls
2037 ./qr
2038 export
PATH=/home/badia/opencl/Mali_OpenCL_SDK_v1.1.0/samples/clinfo:$PATH
2039 export
LD_LIBRARY_PATH=/home/badia/opencl/Mali_OpenCL_SDK_v1.1.0/lib:$LD_LIBRARY_PATH
2040 ./qr/
/
/
Thanks for your help.
Best regards,
Sandra

Hi,
this error usually indicates that your OpenCL installation isn't
working
properly. Does clinfo work from the command line?
Best regards,
Karli
