unable to run example of OpenCV in beagleBone Black
I am trying to run a program using OpenCV in beaglebone black as described at the end of the link https://solarianprogrammer.com/2014/04/21/opencv-beaglebone-black-ubuntu/
I had some compilation issues which I resolved using
pkg-config --cflags --libs opencv test_2.cpp -o test_2
It successfully compiles, but when I try to run using
I get the error:
Ipc_start: LAD_connect() failed: 4
test_2: /build/ti-opencl-zdvBAC/ti-opencl-01.01.06.00/host/src/core/dsp/mbox_impl_msgq.cpp:59: MBoxMsgQ::MBoxMsgQ(Coal::DSPDevice*): Assertion `status == (0) || status == (1)' failed.
I am not sure why I am getting this, and I've been unable to resolve it for a few days already. Please guide me into right direction.

This stems from the use of OpenCL under the covers. The bypass that works for me is to disable opencl by setting:
Optionally, if you're (cross) compiling OpenCV you can add
-DWITH_OPENCL=OFF to your Cmake options to remove OpenCL from the build.
