C++ Kernel

[Silvio Fonseca <silvio at gdora dot com dot br>]

Hello all,

I've been following this list for about two months to get knowledge on 
how g++ works internally. The reason I'm doing it is because I'm writing 
and operating system using C++ (to have full OO design). I got the 
global constructor/destructor to work, got some code from libsupc++ to 
make inheritance and virtual functions to work, but I can't make 
exceptions and RTTI to work, if I just compile the code without 
-fno-exceptions -fno-rtti, in the linking I get:

main.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'

I saw gxx_personality_v0 on libsupc++ but it uses code from other parts 
and I have the felling of "bloating" the code more than needed... (what 
gxx_personality_v0 does anyway??)

Since you are the gurus in g++ where, how can I make a stripped version 
of libsupc++ to get support to: virtual functions/pure virtual classes, 
exceptions and rtti? I need a stripped version because the kernel has to 
small, can't put the entire libstdc++ inside it...

If this list isn't the place to discuss this, please tell me where to 
post :-)

Thanks in advance,
