一个去包的码头图像

Question

我正在尝试使用此dockerfile构建映像。

https://github.com/shantanuo/docker_go_mysql_elasticsearch/blob/master/Dockerfile

我收到错误：

#include <string>
#include "opencv2/opencv.hpp"
using namespace cv;
using namespace std;


std::vector<cv::Point3d> Generate3DPoints();

int main(int argc, char* argv[])
{
    // Read 3D points
    std::vector<cv::Point3d> objectPoints = Generate3DPoints();
    std::vector<cv::Point2d> imagePoints;

    int f = 5;  //focal length

    for (unsigned int i = 0; i < objectPoints.size(); i++)
    {
        cv::Point3d orig_point = objectPoints[i];
        imagePoints.push_back(cv::Point2d(
            f*orig_point.x / orig_point.z,  //x' = f*x/z
            f*orig_point.y / orig_point.z)  //y' = f*y/z
            );
    }
}

std::vector<cv::Point3d> Generate3DPoints()
{
    std::vector<cv::Point3d> points;

    double x, y, z;

    x = .5; y = .5; z = -.5;
    points.push_back(cv::Point3d(x, y, z));

    x = .5; y = .5; z = .5;
    points.push_back(cv::Point3d(x, y, z));

    x = -.5; y = .5; z = .5;
    points.push_back(cv::Point3d(x, y, z));

    x = -.5; y = .5; z = -.5;
    points.push_back(cv::Point3d(x, y, z));

    x = .5; y = -.5; z = -.5;
    points.push_back(cv::Point3d(x, y, z));

    x = -.5; y = -.5; z = -.5;
    points.push_back(cv::Point3d(x, y, z));

    x = -.5; y = -.5; z = .5;
    points.push_back(cv::Point3d(x, y, z));

    for (unsigned int i = 0; i < points.size(); ++i)
    {
        std::cout << points[i] << std::endl << std::endl;
    }

    return points;
}

但是这个回购的原作者已经成功构建了自动图像。这是他的dockerfile ......

在过去几个月里，改变包装的方式是否有所改变？

GPG error: http://ftp.osuosl.org jessie InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUB

还有其他方法可以编写上面的RUN命令吗？

更新

我将RUN命令更改为以下内容：

RUN apt-get update && \
  go get github.com/tools/godep && \
  (go get github.com/siddontang/go-mysql-elasticsearch || true ) && \
  cd /go/src/github.com/siddontang/go-mysql-elasticsearch && \
  make

现在收到此错误：

RUN go get github.com/tools/godep && \
  (go get github.com/siddontang/go-mysql-elasticsearch || true ) && \
  cd /go/src/github.com/siddontang/go-mysql-elasticsearch && \
  make
