 |

Hello.
I am using D 1.0 and I am able to make simple programs. I want to start getting into the object oriented features and classes. However,w hwnever I try to compile modules as classes, I get the following error:
| Code: |

I don't know WTH is going on at all. Has anyone else encountered this problem?
If there's any other info that you need, please let me know and I'll try my best to fill you in (sry, I'm a n00b). |

I really have no idea.
It would possibly help, though, to show your test program's code and the contents of dsss.conf, for completeness.
Actually, I do see one hint. The OPTLINK warning "No Start Address" usually means there's no main() function defined in any of the loaded modules. (Or at least, I have gotten it before, and that was the problem.)

The code for my class:
| Code: |
module MeinClass;
public class MeinClass {
//Instance Variables
private:
int number;
//Default Constructor (notice that we use "this" instead of the class name, which gives us an error)
public:
this() {
this.number = 0;
}
//Overloaded Constructor
this(int num) {
this.number = num;
}
//Accessor Method
int getNumber() {
return this.number;
}
//Mutator Method
void setNumber(int newNum) {
this.number = newNum;
}
}
|
The code for the main class:
| Code: |
module Main;
import std.stdio;
import MeinClass; //The other class must be imported.
public class Main {
void main(string[] args) {
//Instantiate a new MeinClass object using the default constructor
MeinClass foo = new MeinClass();
//And one with the overloaded
MeinClass bar = new MeinClass(7);
//Print out the numbers for both.
writefln("The value of foo.number = ");
writefln();
}
}

My dsss.conf simply contains one line:

Okay, now it all makes sense. 
Just drop the MainClass, moving main() into the module itselfand all shall be shiny and good. In D the main() function is always procedural, as in C.
