⁠Supported tags and respective Dockerfile links

The tag of each eigen-git-mirror docker image is consist of the version of Eigen and the version of basic image. The details are as follows

⁠Usage

In this usage, users can select the corresponding {Tag} based on their requirements.

• Pull the openeuler/eigen-git-mirror image from docker

  docker pull openeuler/eigen-git-mirror:{Tag}
  

  Copy

• Run with an interactive shell

  You can start the container with an interactive shell to compile and run your own code using Eigen.

  docker run -it --rm --name my-eigen openeuler/eigen-git-mirror:{Tag} bash
  

  Copy

• Sample code

  test.cpp

  #include <iostream>
  #include <Eigen/Dense>
  
  using Eigen::MatrixXd;
  
  int main()
  {
    MatrixXd m(2,2);
    m(0,0) = 3;
    m(1,0) = 2.5;
    m(0,1) = -1;
    m(1,1) = m(1,0) + m(0,1);
    std::cout << m << std::endl;
  }
  

  Copy

• Compilation instructions

  Compile the program with the include path of the installed Eigen headers:

  g++ -I/usr/local/include/eigen3 test.cpp -o test_eigen
  

  Copy

• Running the program

  ./test_eigen
  

  Copy

  Expected output:

    3  -1
  2.5 1.5
  

  Copy

• View the container running logs

  docker logs -f my-eigen
  

  Copy

• To get an interactive shell in the running container
