Question

我正在尝试在linux中创建一个使用opencv和tesseract与动态链接的程序的共享库

我跟着link 我的代码如下

`    using System.Windows.Forms;
 using basicObjectLib;

namespace WindowsFormsApplication12
{
public partial class Form1 : Form
{



    public Form1()
    {
        InitializeComponent();
        LoadTreeItems();
 }

    public void LoadTreeItems()
    {
        // Dummy Data 
        // created a DLL Basic Class Object Conatining class definitions of anatomy subanatomy 
        #region Object
        Anatomy an1 = new Anatomy();
        an1.AnatomyID = 1;
        an1.AnatomyName = "Anatomy1";

        Subanatomy san1 = new Subanatomy();
        san1.SubAnatomyID = 11;
        san1.SubAnatomyName = "subAn1";
        an1.SubanatomyList.Add(san1);

        Subanatomy san2 = new Subanatomy();
        san2.SubAnatomyName = "subAn2";
        san2.SubAnatomyID = 2;
        an1.SubanatomyList.Add(san2);


        Anatomy an2 = new Anatomy();
        an2.AnatomyID = 2;
        an2.AnatomyName = "Anatomy2";

        Subanatomy san21 = new Subanatomy();
        san21.SubAnatomyName = "subAn1";
        san21.SubAnatomyID = 21;
        an2.SubanatomyList.Add(san21);

        Subanatomy san22 = new Subanatomy();
        san22.SubAnatomyName = "subAn2";
        san22.SubAnatomyID = 22;
        an2.SubanatomyList.Add(san22);


        Anatomy an3 = new Anatomy();
        an3.AnatomyID = 3;
        an3.AnatomyName = "Anatomy3";

        Subanatomy san31 = new Subanatomy();
        san31.SubAnatomyName = "subAn1";
        san31.SubAnatomyID = 31;
        an3.SubanatomyList.Add(san31);

        Subanatomy san32 = new Subanatomy();
        san32.SubAnatomyName = "subAn2";
        san32.SubAnatomyID = 32;
        an3.SubanatomyList.Add(san32);

        List<Anatomy> anatomyObj = new List<Anatomy>();
        anatomyObj.Add(an1);
        anatomyObj.Add(an2);
        anatomyObj.Add(an3);
        #endregion

        foreach(Anatomy obj in anatomyObj)
        {
            TreeNode parentNode = new TreeNode();
           parentNode = new TreeNode(obj.AnatomyName);

            treeView1.Nodes.Add(parentNode);
            foreach(Subanatomy subObj in obj.SubanatomyList)
            {
                TreeNode childNode = new TreeNode();
                childNode = new TreeNode(subObj.SubAnatomyName);

                parentNode.Nodes.Add(childNode);
            }
        }


    }
    private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
    {

        if (e.Action == TreeViewAction.ByMouse)
        {
            // name of treeNode
            textBox4.Text = treeView1.SelectedNode.Name.ToString();
            // to show the ID
            textBox2.Text = "";
        }
    }

    private void button1_Click(object sender, EventArgs e)
    {
        treeView1.ExpandAll();
    }
  }
  public class WindowsFormApplication
  {
    public static void main()
    {
        Form1 _treeviewDemo = new Form1();

    }
 }
}`

这里Test.cpp是一个简单的文件，如下所示

g++ -c Serial_Key.cpp -fPIC -o cdserial `pkg-config --cflags --libs opencv` -llept -ltesseract
g++ -shared -Wl,-soname,libctest.so.1 -o libctest.so.1.0 cdserial
ln -sf libctest.so.1.0 libctest.so
ln -sf libctest.so.1.0 libctest.so.1
g++ -c Test.cpp -fPIC -o cprog -lctest `pkg-config --cflags --libs opencv` -llept -ltesseract

以某种方式给出了./cprog的错误 ./cprog：无法执行二进制文件：exec格式错误

我觉得我在第二行做了一些基本错误（g ++ -shared）请指导

经过多次头部碾压之后，我在上述问题中发现了几个愚蠢的错误

以下是可能陷入类似问题的其他人的更正流程

首先编译

g ++ -c Serial_Key.cpp -fPIC -o cdserial
通过提及库及其使用soname的路径来创建共享库

g ++ -shared -Wl，-soname，libctest.so.1 -o libctest.so.1.0 cdserial -lopencv_highgui -lopencv_imgproc -lopencv_core -lopencv_imgcodecs -lopencv_videoio -llept -ltesseract -L / usr / local / lib
将soname与库链接

ln -sf libctest.so.1.0 libctest.so ln -sf libctest.so.1.0 libctest.so.1
为测试文件编译和创建对象

g ++ Test.cpp -fPIC -o cprog -lctest -lopencv_highgui -lopencv_imgproc -lopencv_core -lopencv_imgcodecs -lopencv_videoio -llept -ltesseract -L / usr / local / lib
将共享库文件复制到本地lib

cp libctest.so / usr / local / lib cp libctest.so.1 / usr / local / lib cp libctest.so.1.0 / usr / local / lib
确保$ LD_LIBRARY_PATH指向共享库路径

export LD_LIBRARY_PATH = / usr / local / lib
运行

./ cprog

创建在linux中使用opencv的C ++动态库
