Hello guys, tell me please does this tutorial is suitable for mac m1 opencv with C++ installation?I am a freshman.

Glebmaksimov commented 2 years ago

If it is only for python opencv installation, please ,help me to install opencv(C++) on mac m1.

fwiw, CMAKE was not able to find numpy on my machine and did not generate the cv2.cpython file because of it.

adapted command is found below, with added paths to python folders, and disabled building of tests & examples:

lynnwilliam commented 2 years ago

can someone Please post the M1 DYLIB files on the Net? so we can just use them without compiling?

cedricve commented 2 years ago

Disabling ZLIB did make it work

Thank you very much. Finally, I can one warning when run "make -j8". Is it possible to fix it? /Users/wc/opencv/opencv-4.5.0/modules/flann/include/opencv2/flann/index_testing.h:249:11: warning: variable 'p1' set but not used [-Wunused-but-set-variable] float p1; ^ 1 warning generated.

mdsrosa commented 1 year ago

thanks for sharing this, @sayakpaul.

I ran all steps successfully with a couple of changes:

opencv source code

updated Github archive URLs:

opencv: https://github.com/opencv/opencv/archive/refs/tags/4.5.3.zip
opencv-contrib: https://github.com/opencv/opencv_contrib/archive/refs/tags/4.5.3.zip

cmake command

updated cmake command with -S (source code dir path) and -B (build dir path):

❯ cmake \
-DCMAKE_SYSTEM_PROCESSOR=arm64 \
-DCMAKE_OSX_ARCHITECTURES=arm64 \
...
-D BUILD_EXAMPLES=ON -S .. -B .

I had some issues building this, but used the latest 4.8.1 version instead of opencv and the build was successful.

Here the part opencv part of the flow:

wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.8.1.zip wget -O opencv.zip https://github.com/opencv/opencv/archive/4.8.1.zip unzip opencv_contrib.zip unzip opencv.zip cd opencv-4.8.1 mkdir build && cd build cmake \ -DCMAKE_SYSTEM_PROCESSOR=arm64 \ -DCMAKE_OSX_ARCHITECTURES=arm64 \ -DWITH_OPENJPEG=OFF \ -DWITH_IPP=OFF \ -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D OPENCV_EXTRA_MODULES_PATH=/Users/mikael/Downloads/source_code/opencv_contrib-4.8.1/modules \ -D PYTHON3_EXECUTABLE=/Users/mikael/miniforge3/envs/dev/bin/python3 \ -D BUILD_opencv_python2=OFF \ -D BUILD_opencv_python3=ON \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D INSTALL_C_EXAMPLES=OFF \ -D OPENCV_ENABLE_NONFREE=ON \ -D BUILD_EXAMPLES=ON .. make -j8 sudo make install

Sayak，感谢您的精彩描述。老实说，我曾经使用过 venv 而不是 conda，这可能是我的问题。我更喜欢使用 venv，这样就不会混淆几个不同的环境管理。

现在 make 过程在 23% 处中断，并输出以下输出：

'ld：未找到适用于架构 arm64 clang 的符号：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用） make[2]： [lib/libopencv_hdf.4.5.1.dylib] 错误 1make[1]： [modules/hdf/CMakeFiles/opencv_hdf.dir/all] 错误 2 make[1]： 等待未完成的作业.... [ 23%] 已构建目标 opencv_imgproc make： [all] 错误 2'

也许你知道该看什么。提前谢谢。

I also encountered the same problem as you. How did you solve it?
