为beaglebone black交叉编译c++openCV应用程序时出现问题

Trouble with cross-compiling an c++ openCV application for the beaglebone black

我希望有人能快速解决问题,因为我有点沮丧。我正试图在我的Linux Ubuntu 14.04计算机上为我的Beaglebone Black(BBB(交叉编译一个openCV应用程序。我安装了交叉编译器:arm-linux-gnueabihf-gcc-4.8en-arm-linux-gnueabihf-g++-4.8。交叉当我编译一个简单的c++程序而不链接到第三方库(如openCV(时,这些就可以工作了。

因为我想为我的BBB进行编译,所以我在linux计算机上的/mnt/BB/文件夹中安装了beagbone(samba(。我尝试了以下代码(这是http://docs.opencv.org/doc/tutorials/introduction/linux_gcc_cmake/linux_gcc_cmake.html(

#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
    if ( argc != 2 )
    {
        printf("usage: DisplayImage.out <Image_Path>n");
        return -1;
    }
    Mat image;
    image = imread( argv[1], 1 );
    if ( !image.data )
    {
        printf("No image data n");
        return -1;
    }
    namedWindow("Display Image", 1 );
    imshow("Display Image", image);
    waitKey(0);
    return 0;
}

使用以下命令:

arm-g++ -I/mnt/BBB/usr/local/include -I/mnt/BBB/usr/local/include/opencv -L/mnt/BBB/usr/local/lib  -lopencv_calib3d -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc -lopencv_ml -lopencv_objdetect -lopencv_photo -lopencv_shape -lopencv_stitching     -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videoio -lopencv_videostab main.cpp -o main

但我收到以下错误:

main.cpp:(.text+0x4c): undefined reference to `cv::imread(cv::String const&, int)'
main.cpp:(.text+0xa6): undefined reference to `cv::namedWindow(cv::String const&, int)'

有人能告诉我我做错了什么吗?或者还有什么可以做得更好?

感谢

看起来您没有正确链接库!你为什么不使用CMake?

 target_link_libraries(your_project ${OpenCV_LIBS})

在这里,您可以找到关于交叉编译的完整参考:http://www.vtk.org/Wiki/CMake_Cross_Compiling

不管怎样,我在OpenCV论坛群上找到了这个:
