I have C++ code that manipulates images with OpenCV and I'd like to compile it with emscripten
. But emscripten
doesn't find OpenCV if i type:
em++ test.c -s WASM=1 -O3 -o test.js -lopencv_highgu
The warning i get:
WARNING:root:emcc: cannot find library "opencv_highgui"
I guess emscripten
doesn't use my normal include path. So the question is how can i compile my C++/OpenCV program to WebAssembly
You'd first have to compile the entire OpenCV library to WebAssembly and then include it in your project. Here is some additional information: https://hacks.mozilla.org/2017/09/bootcamps-webassembly-and-computer-vision/
