Dear Karl,
The clinfo seems to work well:
*/home/badia/opencl/Mali_OpenCL_SDK_v1.1.0/samples/clinfo/clinfoNumber of
platforms: 1Platform #0 Name: ARM
Platform Version: OpenCL 1.1Number of
devices of platform 0: 2 Device #0 Name:

OpenCL 1.1 Global memory size: 1 GB

(256, 256, 256)*
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
