You can build shared libraries on linux by manually compiling object

Can you give detailed steps for doing this on Linux? Because nobody as

Dpaste seems not working, so, sorry for code

class A

        this(string text)
        {
                writeln("class ctor");
                this.text = text;
        }
        void tell()

                writeln(this.text);
