卸载opencv

1. 自动卸载

# 如果删掉了build，再安装上面编译生成一个
cd /opt/opencv-3.4.10/build

sudo make uninstall

cd ..

sudo rm -r build

2. 手动删除相关文件

可能有些路径存在，可能不存在。

sudo rm -r \
/usr/include/opencv4 \
/usr/lib/cmake/opencv4 \
/usr/lib/python3.9/site-packages/cv2 \
/usr/share/licenses/opencv4 \
/usr/share/opencv4 \
/usr/share/java/opencv4 \
/usr/local/include/opencv4 \
/usr/local/share/opencv4 \
/usr/local/bin/opencv* \
/usr/local/lib/libopencv* \
/usr/local/lib/pkgconfig/opencv4.pc \
/usr/local/lib/cmake/opencv4

3. 卸载并清理配置

# 会删除python的opencv环境

sudo apt \
autoremove \
opencv-doc \
opencv-data \
libopencv-dev \
libopencv2.4-java \
libopencv2.4-jni \
python-opencv \
libopencv-core2.4 \
libopencv-gpu2.4 \
libopencv-ts2.4 \
libopencv-photo2.4 \
libopencv-contrib2.4 \
libopencv-imgproc2.4 \
libopencv-superres2.4 \
libopencv-stitching2.4 \
libopencv-ocl2.4 \
libopencv-legacy2.4 \
libopencv-ml2.4 \
libopencv-video2.4 \
libopencv-videostab2.4 \
libopencv-objdetect2.4 \
libopencv-calib3d2.4

4. 检查是否卸载完成

pkg-config opencv --libs

pkg-config opencv --modversion

pkg-config --cflags --libs opencv

sudo find / -iname "*opencv*"
