lose the 3rd / (http://svn.kuehne.cn/dstress/www/dstress.html#constructor_04) how can you get the addon? (preferably by browser... dont want to have to learn SVN yet) -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

module dstress.addon.constructor_04_A; -> http://svn.kuehne.cn/dstress/addon/constructor_04_A.d You get the idea, don't you ;) You are working on a Window box? Get a nice Explorer extendsion: http://tortoisesvn.tigris.org/ Thomas

What's the problem? The code on the web page is incomplete.

It's one of the few multi file testcases: http://svn.kuehne.cn/dstress/run/constructor_04.d http://svn.kuehne.cn/dstress/addon/constructor_04_A.d See the note in the dstress.addon.constructor_04_A module. Thomas

I think the problem is that the constructor is private.

In article <cn0cp5$if9$2 digitaldaemon.com>, Walter says...I think the problem is that the constructor is private.
That's what's causing the error, but I think it's still a compiler bug. If you move the class definitions in constructor_04_A into constructor_04 then the code compiles just fine. Also, if you change the definition of Derived to this: # class Derived : Base{ # private: # // constructor will be wrongly generated here, so it is private. # public: } then the code compiles fine as well. The problem seems to have something to do with import. Sean

No problem, I found and fixed it. Thanks, -Walter

"friendly" to eachother. In my view the problem is that a ctor is silently generated in the Derived class. If it needs to be created I'd expect the same access rights as for the super(Base class) constructor. The remaining problem is of course the module member ship and it's consequences. Sample: Base is in module A with a private ctor. Derived is in module B and has no explicit ctor. Is Derived's silent ctor accessible from module A? Is Derived's silent ctor accessible from module B? Thomas PS: Sean, I've added your sample. http://svn.kuehne.cn/dstress/run/constructor_06.d http://svn.kuehne.cn/dstress/addon/constructor_06_A.d

The import behavior is expected. Remember everything in one source file is "friendly" to eachother.
Oops! I'd forgotten.In my view the problem is that a ctor is silently generated in the Derived class.
I don't have a problem with an auto-generated ctor, but it should be public by default. If the programmer wants his class to not be publically contructible then he should put a default contructor in private scope. But as Walter has already fixed this, I suppose we can test the new behavior in .107 :) Sean
