Does anyone know of a good easy to port to kernel space STL. I have come across quite a few and they all rely heavily on exceptions and lots of headers I don't have and don't wish to create. I would like to be able to use vectors, lists, dequeues, and at least some of the associative containers. I thought I would ask before I try my hand at ripping the exceptions out and trying to make up the rest of the headers.

Thanks,
Frank

You could write your own. It's shouldn't be too hard. (That is, if you just write a small subset of it.)

Well does anyone have a good reference on the internals of the STL? There are plenty of good references on the interface but few on the internals.

Candy should know. He does a lot of reading about these types of things. He had ought to find this message is no one else replies with any good information about that sort of stuff.

I bought "The C++ Standard - Incorporating Technical Corrigendum 1" (published by Wiley), but there is also the final Draft of the C++ Standard (also including technical corrigendum 1. Just for the record: imho in some STLs you can disable exceptions with a define or something similar.

SGI used to have good docs on the interfaces, and insight into the "under-workings" of the library; I used to use those sites whenever developing on top of STL, at least. I assume they would be of some use if implementing your own STL, as well (but they are mostly geared towards development on top of STL).

A searched google, and found this -- looks like the same site I remember:

You can disable exceptions fairly easily (IIRC it's a define indeed), replacing allocation & such by your own should be trivial. Do notice what functions return when they fail without exception, because you should (must) handle those cases.

Ok now then does anyone know of a good STL implementation that I can try to port? I have downloaded a couple and most of them just fail with 100s of compiler warnings. I could try to fix them but I am developing an OS not a STL.

Have you tried uSTL?

or STLPort ?

I ported SGI STL to my kernel before. It wasn't too hard. You can disable exceptions by editing stl_config.h; apart from that, the only problem I found was that it calls fprintf(stderr, ...) in a few places.

EDIT: I just noticed that it needs new.h. That means you have to define operator new, but the wiki explains that (under "new and delete").

Well , I know there's a Chinese provide a simple STL (Both With C , which amazing me a lot , and C ++ ) porting to x86ã€
