编译 opencv wasm¶
0. 配置 emscripten 环境¶
sudo apt install fish
mkdir dev && cd dev
mkdir env && cd env
git clone https://github.com/juj/emsdk.git
cd emsdk
./emsdk install latest
./emsdk activate latest
# 编辑 ~/.config/fish/config.fish
# 假设 sdk 的位置在 ~/dev/env/emsdk
echo 'source ~/dev/env/emsdk/emsdk_env.fish' >> ~/.config/fish/config.fish
# 启动 fish
fish
# 检查 emcc 版本
emcc --version
1. 编译官方的 js 接口¶
1.1 编译 opencv¶
# 下载源码
git clone https://github.com/opencv/opencv.git
emcmake cmake ../ \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS=OFF \
-DBUILD_opencv_js=ON \
-DBUILD_LIST=core,imgproc \
-DBUILD_EXAMPLES=OFF \

-DCMAKE_EXE_LINKER_FLAGS="-msimd128 -s USE_PTHREADS=0"
# 编译
emmake make -j$(nproc)
2. 编译静态 opencv wasm¶
2.1 构建环境¶
# 下载源码
git clone https://github.com/opencv/opencv.git
emcmake cmake ../ \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS=OFF \
-DBUILD_opencv_js=OFF \
-DBUILD_LIST=core,imgproc,imgcodecs \
-DBUILD_EXAMPLES=OFF \
-DBUILD_TESTS=OFF \
-DBUILD_PERF_TESTS=OFF \
-DBUILD_DOCS=OFF \
-DBUILD_opencv_apps=OFF \
-DBUILD_opencv_python_bindings_generator=OFF \
-DBUILD_opencv_ts=OFF \
-DBUILD_WITH_DEBUG_INFO=OFF \
-DWITH_ITT=OFF \
-DWITH_OPENCL=OFF \
-DWITH_TBB=OFF \
-DWITH_IPP=OFF \
-DWITH_QT=OFF \
-DWITH_GTK=OFF \
-DWITH_OPENGL=OFF \
-DWITH_FFMPEG=OFF \
-DWITH_JPEG=ON \
-DWITH_PNG=ON \
-DWITH_WEBP=OFF \
-DWITH_TIFF=OFF \
-DWITH_1394=OFF \
-DWITH_V4L=OFF \
-DWITH_GSTREAMER=OFF \
-DWITH_PROTOBUF=OFF \
-DWITH_ADE=OFF \
-DCV_DISABLE_OPTIMIZATION=ON \
-DENABLE_SSE=OFF \
-DENABLE_SSE2=OFF \
-DENABLE_SSE3=OFF \
-DENABLE_SSSE3=OFF \
-DENABLE_SSE4_1=OFF \
-DENABLE_SSE4_2=OFF \
-DENABLE_AVX=OFF \
-DENABLE_AVX2=OFF \
-DCMAKE_C_FLAGS="-O3 -msimd128" \
-DCMAKE_CXX_FLAGS="-O3 -msimd128" \
-DCMAKE_INSTALL_PREFIX=./install
此时, 会有以下警告
修正做法emcmake cmake ../ \ -DCMAKE_BUILD_TYPE=Release \ -DBUILD_SHARED_LIBS=OFF \ -DBUILD_opencv_js=OFF \ -DBUILD_LIST=core,imgproc \ -DBUILD_EXAMPLES=OFF \ -DBUILD_TESTS=OFF \ -DBUILD_PERF_TESTS=OFF \ -DBUILD_DOCS=OFF \ -DBUILD_opencv_apps=OFF \ -DBUILD_opencv_python_bindings_generator=OFF \ -DBUILD_opencv_ts=OFF \ -DBUILD_WITH_DEBUG_INFO=OFF \ -DWITH_ITT=OFF \ -DWITH_OPENCL=OFF \ -DWITH_TBB=OFF \ -DWITH_IPP=OFF \ -DWITH_QT=OFF \ -DWITH_GTK=OFF \ -DWITH_OPENGL=OFF \ -DWITH_FFMPEG=OFF \ -DWITH_JPEG=ON \ -DWITH_PNG=ON \ -DWITH_WEBP=OFF \ -DWITH_TIFF=OFF \ -DWITH_1394=OFF \ -DWITH_V4L=OFF \ -DWITH_GSTREAMER=OFF \ -DWITH_PROTOBUF=OFF \ -DWITH_ADE=OFF \ -DCPU_BASELINE=WASM128 \ -DCPU_DISPATCH=NONE \ -DCMAKE_C_FLAGS="-O3 -msimd128" \ -DCMAKE_CXX_FLAGS="-O3 -msimd128" \ -DCMAKE_INSTALL_PREFIX=./install
