I found a simple kernel written in D. But it should be compiled with a 
really old dmd release...

Is there anyone who know to make a simple operating system in D made up 
of a boot loader and a kernel?
I'm trying to make it but it's hard to link D object files with libraries.
It works fine by compiling the kernel without using any library, but i 
can't use classes and other D stuff without them!
I need to specificy -Ttext 0x10000 (to set the text section entry point) 
but i can't if i link libraries...

Any suggestion?

I don't know what "simple kernel" you found - there are several out
there. The one I've played around was Mike Wynn's. It compiles, runs
and supports classes. 

Be warned that it is quite rudemental and certanly contains bugs.

FYI

I just created a wiki page about D kernel efforts:
http://www.prowiki.org/wiki4d/wiki.cgi?KernelWithD

Not much there, but people can add to it if they know more.

Hi, I have spent some time to get a basic "kernel" (I wouldn't call it a  
kernel yet) to boot. It's possible to do screen output but no input yet.  
That would be next. But getting input already requires a lot of pre-work  
with interrupt controlers etc.

 I'm trying to make it but it's hard to link D object files with  
 libraries.

Hard? Hmm... The thing is, you can't use any libraries because those  
functions are using operating-system functions. And those are not  
available for your own kernel. So you first have to implement all  
functions that the library uses before you can use this library to futher  
compiler programs.

 It works fine by compiling the kernel without using any library, but i  
 can't use classes and other D stuff without them!

Not true. You can use classes but you can't use the posted code here. Try  
to get phobos to work, than you can compile most of the avaiable (non-gui)  
code.

 I need to specificy -Ttext 0x10000 (to set the text section entry point)  
 but i can't if i link libraries...

I don't what you try to do with libraries. Just forget them when doing a  
kernel. You need to be able to create a special executable and boot this  
one. I just used "grub" for this and an ELF exectuable.

I hope this helps a bit.
