(Sorry for my poor English)

I am developing a kernel in C++, and would like to use RTTI and exceptions. The compiler used is the DJGPP (GCC 4). I ask this because I don't have found information anywhere.

I founded this References:

But could not help me much. Does anyone already tried a kernel 100% in C++?

Thank you.

First, I'd recommend making your own cross compiler rather than relying on djgpp. You can follow the GCC Cross-Compiler tutorial to achieve this (you'll also need cygwin as I don't think djgpp has the infrastructure for running configure scripts?). Once you have that, the only extra thing you need for rtti/exceptions is the libsupc++ library, which has a few extra requirements, see libsupcxx. Alternatively, the OS Specific Toolchain tutorial has complete instructions for doing it from scratch, and everything seems to fit together better.

I needed something more specific. Someone knows only a tutorial for that matter?

Here's the article that discusses Visual C++'s internal implementation of exception. The trick is that the internal implementation is not defined by the standard, so it depends on specific compiler as well as underlying operating system.
