digitalmars.D.learn - Cannot make a personalized exception

I'm trying to make a custom Exception class with this :


class MyException : Exception
{
    static char[] s = "My Exception";
    this()
    {
			super(s);
    }

    char[] toString()
    {
				return s;
    }
}

it compile well, until I want to throw it :/
When I put the line : 

throw new MyException();

I get that error :
webcache.obj(webcache)
 Error 42: Symbol Undefined _D4util10linkedlist13TestException7__ClassZ
webcache.obj(webcache)
 Error 42: Symbol Undefined
_D4util10linkedlist13TestException5_ctorMFAaZC4util10linkedlist13TestException
--- errorlevel 2



The two class ( Exception and thrower class ) are in the same file. I tried
Copy / Past examples from the site, but it still donc work. An idea ?

The code I join don't work, but I tried just copy, past and rename de
LinkedList class to LinkedListTestException, and it worked.

The Exception is thrown in the get function of the LinkedList class (it's an
OutOfBoundsException).

Hope you will find what I missed ^^

Any particular reason you're overriding toString to do exactly what it 
already does?

It was just a try, but deleting the toString function don't change my problem :/
I think the linker cannot find the modules because there are not in it's
include path. I will try to compile all the files simultaneously in a single
line.
The problem is not present when I don't use modules.
I saw phobos has a .a file in the lib directory, should my modules have one too
?

sorry for my english.

That is a lib file for linux, you shouldn't need to make a lib file of your 
own.


 sorry for my english.


Why is it that only the forever who have good English apologies for it?  :b

I've often wondered.  In fact, one of my personal friends with the best command
of the 
language is a Netherlander.  (Sure their language isn't as far off, but still.)
 I think 
the common -- albeit accurate -- axiom of "English is the hardest language to
learn" makes 
them more self-conscious, perhaps?  Somebody set us up the bomb.  All your base
are belong 
to us.

Well, over here in the Netherlands English is a required[1] course for 6 
to 8 years[2] of school, so the Dutch speaking English relatively well 
(on average) is not entirely unexpected. Also, the master's phase of 
university education is now taught entirely in English.

By the way, I've heard that /Dutch/ is actually one of the hardest 
languages to learn[3]...


[1] Or at least, it was for me. I'm not sure what it's like right now, 
they overhauled the education system just after my year...
[2] Depending on the "level" of education you're attending.
[3] (as a second language)

Actually, there's a scale for this. I can't recall the name of it, but 
it ranks languages mostly by group according to several criteria. On one 
end of the scale are latin- and germanic-based languages. On the other 
end is Chinese. The closer two languages are to each other the easier it 
is for speakers of each language to learn the other. The farther apart 
they are, the more difficult to learn.

Not to nitpick or anything but I believe you mean "Somebody set *up* 
*us* the bomb."  I'm guessing AYBian is not your first language.  :-)

You know, just to be anal, I went and looked it up... and you're right.  Heh.
