How to embed C++ into OS kernel?

Question

C++ / C#

I have a core in C, and a bunch of libraries for C ++.
How do I embed C++ support into a written kernel?
Assembly code(kernel.asm)

bits 32
section .text
        ;multiboot spec
        align 4
        dd 0x1BADB002        
        dd 0x00            
        dd - (0x1BADB002 + 0x00)  

global start
global keyboard_handler
global read_port
global write_port
global load_idt

extern kmain 		
extern keyboard_handler_main

read_port:
  mov edx, [esp + 4]
      
  in al, dx	
  ret

write_port:
  mov   edx, [esp + 4]    
  mov   al, [esp + 4 + 4]  
  out   dx, al  
  ret

load_idt:
  mov edx, [esp + 4]
  lidt [edx]
  sti 				
  ret

keyboard_handler:                 
  call    keyboard_handler_main
  iretd

start:
  cli 			
  mov esp, stack_space
  call kmain
  hlt 		

section .bss
resb 8192; 8KB for stack
stack_space:

Is it possible to complete the core but already with C++ and with the same architecture (i386)?

It's just that there is a lot of information about C ++ and a pseudo graphical interface will be easier to do

Answer 1

C++ is a programming language. There is no support for it in any kernel.
The kernel is the part of the operating system that provides the main interface for running processes and system functions that can be used. You can write the kernel in anything, and there is no connection with the supported languages.
And C++ is supported primarily by the compiler, which has nothing to do with the kernel.
A slightly different question is the linker that creates a binary or library, and your kernel, in theory, should be able to run this binary and use the library.
In total, before "connecting C ++ to the kernel", you should clarify how the OS architecture works and ask the right question
