c++ - 使用已编译版本的 openCV 时出错

Question

我已经使用了用于 Raspberry Pi 的 openCV 的已编译版本。 link for anyone who is interested

尝试使用此命令行进行编译后 g++ test3.cpp -o test3 -I/usr/local/include/ -lraspicam -lraspicam_cv -L/opt/vc/lib -lmmal -lmmal_core -lmmal_util -I/usr/include -lopencv_core -lopencv_highgui -lopencv_imgproc -lwiringPi -lpthread

我收到以下错误行。

//usr/local/lib/libopencv_stitching.so.2.4: undefined reference to `cv::gpu::ensureSizeIsEnough(int, int, int, cv::gpu::GpuMat&)'

//usr/local/lib/libopencv_calib3d.so.2.4: undefined reference to `cv::parallel_for_(cv::Range const&, cv::ParallelLoopBody const&, double)'

您尚未将可执行文件链接到程序所需的多个库

尝试使用这个:

g++ -lpthread `pkg-config opencv --libs` -I/usr/local/include/ -lraspicam -lraspicam_cv -L/opt/vc/lib -lmmal -lmmal_core -lmmal_util -I/usr/include -lwiringPi test3.cpp -o test3
