The problem is we need to remove the opencl library, and add the libopencl.c file to the appropriate make-ish file.
(Which should be pretty much all devices that do support opencl.) In theory, that means we should be able to use it on any device that has an opencl library installed. (TM) Instead, we downloaded opencl stubs that dynamically open the appropriate libopencl.so library that already exists on the device and uses that. Since this library is device specific, its kind of a bad idea.
OPENCV FOR MAC 2017 TUTORIAL INSTALL
The build by default uses a libOpenCL.so that we’re supposed to pull from the device, and then later link with the app and install back on the device. # need to add the opencl stub to the build and remove the OpenCL libraryĪt this point you’re almost good to start building, but we need to change one thing. # Set the folder where we are going to compile opencv, it will be used when we build the projectĮxport OPENCV_ANDROID_SDK=$BUILD_HOME/build # Grab the opencl stub and copy the c and h files into placeĬp libopencl-stub/include/libopencl.h opencv-3.3.0/samples/android/tutorial-4-opencl/jni/Ĭp libopencl-stub/src/libopencl.c opencv-3.3.0/samples/android/tutorial-4-opencl/jni/ # Download the multiplatform version of the C++ OpenCL WrapperĬd include/CL/ & mv cl.hpp cl.hpp.orig & wget & cd. # Copy the OpenCL headers used to compile OpenCVĬp -r $BUILD_HOME/opencv-3.3.0/3rdparty/include/opencl/1.2/CL include/ Now we grab all of the sources we need to build:Įxport BUILD_HOME=$HOME/opencv # change as you would like Assuming your sdk is installed in ~/Library/Android/sdk, run this on the terminal: You’ll have to download and use an old version. I’ve been unable to get opencv working at all in Android Studio, but here’s a (slightly painful) way of getting it working on MacOS, at least as of the December, 2017.įirst, current android sdk tools (ie ‘android’) will not work.
