Is it serious doc ?

Alright my first post is almost unreadable so restarting with the http version... Hope it's going to be better.

Why are you using version 2.008??? It was one of the first 'proof of concept' alpha test versions. It wasn't intended for serious use. Any version prior to about 2.040 was useful only for finding the most severe compiler bugs.

Thx Don for the reply. It actually is the only version available for Gentoo right now, so I'm going to see if anyone's interested in bringing a more recent version of DMD for this distribution.

Just download the zip file. It's easy to to just put it in your home directory somewhere and use it. Sure, it would be great if gentoo got a more up-to-date version, but you can just download it yourself and use it quite easily, and it's self-contained if you don't copy the files to /usr/bin and the like, so uninstalling it later is a breeze.

P.S. The Bug listed isn't really intended to be posted to. The bug tracker sends notifications to this list and you sign up for the list if you want those notifications. You should be posting to one of the other lists like Learn or D. And if you have a bug that you want to report rather than looking for help on something, you can just report it to the tracker: http://d.puremagic.com/issues/

Thx a lot Jonathan for all the good news.
I thought only the rpms were actually containing the binaries and the zip only a source archive for people to build
locally. As you might know rpms are not really the Gentoo's philosophy so I wanted to stick to Gentoo's portage. I
just gave a try to the zip and you're right, it's working like a breeze : )

I'm a newcomer to D and actually enjoying Andrei's book. Right now it feels to me like the language I'm dreaming of for years : terse, expressive, efficient. Let's see if it's true in the long run.

Thanks also for pointing out the bug reporting strategy, I noticed the way my messages appeared in the list was quite different from the other and I was telling to myself I was surely out the normal path.
