Hey,

I'm trying to develop a kernel in D2. It works fine if I don't use 
classes but as soon as I try to use classes, it complains about the lack 
of object.d.

So, I set out on a quest to develop a simple object.d that doesn't need 
to import anything to work apart from basic memory functions like 
malloc, etc (for now). I'm partially basing it off the one included in 
the D runtime. The problem is that I'm trying to find a minimal object.d 
that doesn't try to pull in too much. Has this been done before? 
Whenever I try to create one that is not the original one, I just make 
the compiler generate a segmentation fault.

I've also been trying to find a kernel project that someones started 
with classes in D2 but have yet to find one. Does anyone know one?

Thanks,
Nebster

There's a kernel written in D1: http://wiki.xomb.org/

Yes, I've seen xomb, titan, osian and one posted on this newsgroup. 
Unfortunately they are all D1 kernels. The problem I'm having is 
creating a small object.d for D2 without causing the compiler to seg fault

Thanks for trying to help though!

Well, thanks for the info!

Were you calling the constructors and destructors in your code? It seems 
as if you just disregarded them by the sound of things! They are 
outputted as a symbol in the object.

Do you still have a copy of your code? I would love to look over it!

Thanks,
Nebster

I pretty much couldn't get ANYTHING related to Object to work, which I 
think was ultimately because thread-local storage was ruining 
everything, and I was spending way too much time on it.
The only thing I got working was pretty much C code written in D... 
structs & unions, fun stuff. :)

I don't remember how I built this... I used the Geany text editor, 
because it also had some (minimal) project support, but I have no idea 
what the command-line parameters and all that stuff were. (I remember 
doing a LOT of work with .obj files and stuff to get everything working, 
though...)

Feel free to try building it, good luck.
I've attached the file (7-zip archive)... let me know if it didn't 
attach correctly.

Thanks for that, it's another kernel to add to my collection ^^
Unfortunately it doesn't have an object.d that is for D2 (latest).
Your code looks interesting though! I'll have a look through it!
