Estoy intentando compilar OpenCV 4.1.0 en Mac siguiendo este blog:https://www.learnopencv.com/install-opencv-4-on-macos/
Aquí está la línea de comando para el cmake preparatorio, que fue exitoso:
cmake -DOPENCV_EXTRA_MODULES_PATH=/git/opencv_contrib-4.1.0/modules -DPYTHON_DEFAULT_EXECUTABLE=python3 -DCMAKE_CXX_COMPILER=/usr/local/gcc-9.1/bin/g++-9.1 -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_opencv_python2=False -DBUILD_opencv_python3=True -DPYTHON3_EXECUTABLE=python3 ../
Entonces la marca
make -j4
Eso falla con internal compiler error:
/usr/local/gcc-9.1/include/c++/9.1.0/limits:1668:7: internal compiler error: Illegal instruction: 4
1668 | max() _GLIBCXX_USE_NOEXCEPT { return __FLT_MAX__; }
| ^~~
Aquí está el resultado completo:
