Hello world OS

[Afflictedd2]

Hi, I'm trying to compile a hello world OS, but I get the following error

[flethuseo@localhost Program]$ g++ -c copyboot.cpp
copyboot.cpp:10:19: error: bios.h: No such file or directory
copyboot.cpp: In function ‘void writebootsector(char*, int)’:
copyboot.cpp:27: error: ‘biosdisk’ was not declared in this scope
[flethuseo@localhost Program]$

I've tried adding bios.hs to the folder but I get nowhere.. maybe I'm just adding the wrong ones.. anyone know how I can fix this error

Hello,

1. Make sure you have a main.cpp file (which compiler wants). If you dont have one please rename copyboot.cpp to main.cpp
2.make sure you have a "bios.h" in same directory as main.cpp
3. If ‘void writebootsector(char*, int)’: is a main function please rename it to main. Also main function must be "int" and must return 0 or 1 value (which tells to OS if program finished as well.
4. Declare biosdisk.


I hope that helps,

Jan
