'Build OpenCV 4.5.5 on mac mini m1 openjdk 17
I'm trying to build OpenCV 4.5.5 on a mac mini m1 as follows
- installed openjdk 17
- created folder ~/build_opencv in user home and cd to it
- from this folder call
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/opencv \ -D JAVA_INCLUDE_PATH=$JAVA_HOME/include \ -D JAVA_AWT_LIBRARY=$JAVA_HOME/jre/lib/amd64/libawt.so \ -D JAVA_JVM_LIBRARY=$JAVA_HOME/jre/lib/arm/server/libjvm.so \ -D BUILD_opencv_python2=OFF \ -D BUILD_opencv_java=ON \ -D INSTALL_PYTHON_EXAMPLES=OFF \ -D INSTALL_C_EXAMPLES=OFF \ -D OPENCV_ENABLE_NONFREE=OFF \ -D BUILD_EXAMPLES=ON ../opencv-4.5.5
- call
make -j7
Got a lot of warnings like

and final message

Also tried openjdk 15 and 18 but led to same result.
Any ideas to fix this would be appreciated.
