Hi
I've recently got over the Compute Library OPenCL.so problem and have moved on to trying to run the examples. I compiled natively on an Odroid XU4 with neon=1 and opencl=1 using "scons Werror=1 -j8 debug=0 neon=1 opencl=1 os=linux arch=armv7a build=native"
I could run the neon example ok:-
odroid@odroid:~/ComputeLibrary-17.12/build/examples$ LD_LIBRARY_PATH=~/ComputeLibrary-17.12/build ./neon_convolution
./neon_convolution
Usage: ./build/neon_convolution [input_image.ppm]
No input_image provided, creating a dummy 640x480 image
Test passed
When trying the opencl version :-
odroid@odroid:~/ComputeLibrary-17.12/build/examples$ LD_LIBRARY_PATH=~/ComputeLibrary-17.12/build ./cl_convolution
./cl_convolution
Usage: ./build/cl_convolution [input_image.ppm]
No input_image provided, creating a dummy 640x480 image !!!!!!!!!!!!!!!!!!!!!!!!!!!
ERROR in load_program src/core/CL/CLKernelLibrary.cpp:765: Kernel file ./cl_kernels/convolution3x3.cl does not exist. No such file or directory !!!!!!!!!!!!!!!!!!!!!!!!!!!
Test FAILED
This looks like an OpenCL run/compile failure!I copied the cl_kernels directory from ~/ComputeLibrary-17.12/src/core/CL into ~/ComputeLibrary-17.12/build/examples and ran it again:-
Is there some $PATH or other ENV value that needs set up, so that the scons compiled build code points to the original source directory rather than in the build directory or is there something I've missed in the Scons command?
