Code::Blocks 配置 OpenCV 4.2.0

1. 头文件目录配置

(base) yongqiang@famu-sys:~$ pkg-config --cflags opencv4 -I/usr/local/include/opencv4/opencv -I/usr/local/include/opencv4 (base) yongqiang@famu-sys:~$

1.1. Release -> Search directories -> Compiler

Project -> Build options… -> Release -> Search directories -> Compiler

/usr/local/include /usr/local/include/opencv4 /usr/local/include/opencv4/opencv2

1.2. Debug -> Search directories -> Compiler

Project -> Build options… -> Debug -> Search directories -> Compiler

/usr/local/include /usr/local/include/opencv4 /usr/local/include/opencv4/opencv2

2. 库文件目录配置

(base) yongqiang@famu-sys:~$ pkg-config --libs opencv4 -L/usr/local/lib -lopencv_dnn -lopencv_stitching -lopencv_ml -lopencv_photo -lopencv_objdetect -lopencv_gapi -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_video -lopencv_calib3d -lopencv_features2d -lopencv_imgproc -lopencv_flann -lopencv_core (base) yongqiang@famu-sys:~$

2.1. Release -> Search directories -> Linker

Project -> Build options… -> Release -> Search directories -> Linker

/usr/local/lib

2.2. Debug -> Search directories -> Linker

Project -> Build options… -> Debug -> Search directories -> Linker

/usr/local/lib

3. 链接库文件配置

把/usr/local/lib下 OpenCV 的所有.so文件全部加入到 Link libraries 中。

3.1. Release -> Linker settings -> Link libraries
