分享请教一下使用opencv使用arm-linux-gnueabihf-g++-4.8编译后的库编写的代码出错的问题
我用opencv2.4.13中自带的platforms/linux/arm-gnueabi.toolchain.cmake文件编译好的库，再使用arm-linux-gnueabihf-g++-4.8编译代码的时候后会出错。
编译命令arm-linux-gnueabihf-g++-4.8 -L/usr/local/opencv-arm/lib -I/usr/local/opencv-arm/include -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab -lrt -lpthread -lm -ldl -o test DisplayImage.cpp（为了防止少某些库，我就全加上了）
错误信息：
/tmp/cc8j2z1H.o: In function `main':
DisplayImage.cpp:(.text+0x7e): undefined reference to `cv::imread(std::string const&, int)'

游牧有妞比的大神知道为什么阿

代码如下，x86的opencv可以编译通过并成功执行
#include "opencv2/opencv.hpp"
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
if(argc != 3)
return -1;
Mat srcs = imread(argv[1]);
vector<int> param = vector<int>(2);
param[0] = CV_IMWRITE_JPEG_QUALITY;
param[1] = 50;
imwrite(argv[2], srcs, param);
}
