我正在尝试按照此博客在 Mac 上构建 OpenCV 4.1.0：https://www.learnopencv.com/install-opencv-4-on-macos/
这是准备 cmake 的命令行 - 成功了：
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 ../
然后制作
make -j4
失败的原因如下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__; }
| ^~~
完整输出如下：

openCV如果有任何人士曾在 Mac 上（以及使用）成功构建过此版本，opencv_contrib我将非常感谢他们的提供建议。
