Ok, so now we really need to actual compiler call from CMake. In build/:
$> cmake .. -DCMAKE_VERBOSE_MAKEFILE=On
$> make blas1
(send output)
Thanks and best regards,

Hi,
The example that you mention is not in the new examples folder. However,
I tried with blas1 and it does not work:
jbelloch@odroid:~/EQU_FILTERING_sandra/ViennaCL-1.7.1/build$
examples/tutorial/blas1
terminate called after throwing an instance of
'viennacl::ocl::unknown_error'
what(): ViennaCL: FATAL ERROR: ViennaCL encountered an unknown
OpenCL error. Most likely your OpenCL SDK or driver is not installed
properly. In some cases, this error is due to an invalid global work
size or several kernel compilation errors.
If you think that this is a bug in ViennaCL, please report it at
viennacl-support@lists.sourceforge.net
<mailto:viennacl-support@lists.sourceforge.net> and supply at least the
following information:
* Operating System
* Which OpenCL implementation (AMD, NVIDIA, etc.)
* ViennaCL version
Many thanks in advance!
Aborted
Best regards,
Sandra

Can you try to build in a subfolder? Maybe there's some issue with the
build inside the project folder. Also, it would be good to start with a
fresh ViennaCL folder just to rule out any side-effects.
$> cd /path/to/ViennaCL
$> mkdir build
$> cd build
$> cmake ..
-DOPENCL_LIBRARY=/home/jbelloch/EQU_FILTERING_sandra/opencl/lib/libOpenCL.so
$> make
ENABLE_OPENCL is set by default. We can skip ublas for this.
Then run via
$> examples/tutorial/blas1-opencl
inside the build folder. Does this work?
Best regards,
Karli
