Be care when move a code from static library to dynamic library.

// file: main.cpp
#include <iostream>

using namespace std;

int main()
{
    cout << "main is running" << endl;
    return 0;
}


// g++ main.cpp y.cpp x.cpp
// output:
X is created
Y is created
main is running

// g++ main.cpp -Llibx-so.1.0.1 -Lliby-so.1.0.1
// output:
main is running
