Build instructions

Prerequisites:

• .NET Framework 4.6.1 or latest Mono
• NASM Assembler (sudo apt-get install nasm)
• mtools (sudo apt-get install mtools)
• xorriso (sudo apt-get install xorriso)
• Optional: qemu or bochs for emulation.

git clone --recursive https://github.com/lonos-project/lonos.git
cd lonos 
./lonosctl configure patch apply # Some patches are requied, because Mono does not support
                                 # .NET Framework v4.7.2 yet
./lonosctl configure mosa        # Build the Mosa-Compiler
./lonosctl build all             # Builds the lonos kernel and creates a disk image

Run it with ./lonosctl run qemu x86 or ./lonosctl run bochs x86

The technology behind this project

• The most important part of the Lonos project is the Mosa-Compiler, wich is written in pure C#. The Mosa-Compiler converts an already compiled Assembly (build via msbuild or xbuild, default compiler from .NET/Mono) into native Code.
• build some requied Assembler-Code and append it to the native binary. The Assembler code ist mostly used for early initalization.
• Building the Operating System Disk Image, with Grub2 as Bootloader

Status of the OS

This is a research project / proof of concept. So it isn't a fully functional OS. This is implemented:

• Build tool chain
• Reading Kernel-Embedded ELF-Files
• Integration of assembler code within the kernel.
• Output kernel log messages via serial interface to a text file on the host
• Scrollable screen output
• Setup GDT
• Basic Interrupts
