NOTE: THESE INSTRUCTIONS ARE TARGETING LINUX BASED SYSTEMS, IF YOU DON'T USE LINUX THEN INSTALL LINUX ON A VIRTUAL MACHINE TO FOLLOW THESE
A: Step 1 - Installing the required build tools
I am using Ubuntu for this guide, the following command will install the required tools on any Ubuntu based distro.
This installs:
NASM (for assembling the bootloader)
If you are not using an Ubuntu based distro then use any equivalent command for your distro's package manager, these tools should be easily available for all distros.
Step 2 - Building the OS
This process will work on any Linux distro as long as you have the previously stated dependencies installed. There are 2 commands you can use for this:
How do I compile and run this project?
sudo apt install build-essential binutils nasm clang qemu-system-x86
LD (the GNU linker for linking the code into one image)
Clang (for compiling the C code)
GCC (backup compiler, same use as Clang)
Make (for automating all the commands needed)
QEMU (emulator, for testing the OS)
make all - This produces an os.img file
make run - This produces an os.img file as well, but it also runs the img file in qemu so you can test it out.
