OpenCV WebAssembly
OpenCV WebAssembly
我尝试 运行 本教程 http://videocortex.io/2017/opencv-web-app/ 来构建和试用 OpenCV WebAssembly。但我无法完成步骤 "The Build System" 我构建了 emscripten 1.38.21，安装了 Python 2.7.5.3_64bit 和 CMAKE 3.13.2 但最后出现错误：
我是不是漏掉了什么？
当我 运行 emcc -v 我也得到了一些错误：

有人成功将 OpenCV 编译成 WebAssembly。您可以访问 GitHub repository 并按照以下步骤操作：
- 获取源代码：
git clone https://github.com/ucisysarch/opencvjs.git
cd opencvjs
git clone https://github.com/opencv/opencv
cd opencv
git checkout 3.1.0
- 安装 Emscripten：
./emsdk update
./emsdk install sdk-incoming-64bit --shallow
./emsdk activate sdk-incoming-64bit
source ./emsdk_env.sh
- 将 OpenCV 构建为 WebAssembly。
python make.py --wasm
