在Clion中运行程序
#include/home/johnqi/ClionProjects/opencv/main.cpp:7:对‘cvLoadImage’未定义的引用#include #include "opencv/highgui.h" using namespace std; int main() { IplImage *img=cvLoadImage("image/first-5.bmp"); cvNamedWindow("example", CV_WINDOW_AUTOSIZE); cvShowImage("example",img); cvWaitKey(0); cvReleaseImage(&img); cvDestroyWindow("example"); } 会报错误:
这主要的问题是配置CMakeLists.txt文件时出错导致的,应该在CMakeLists.txt文件中添加一句
target_link_libraries(opencv -I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so)
注意:不同的系统添加的链接库文件可能不同,具体的库文件可以通过在ubuntu终端下输入命令pkg-config --cflags --libs opencv获取.
其中opencv为当前项目的名称
