(first sorry for my poor English)

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.

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.

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 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.
