This project was made for our Computer Architecture subject at ITBA University (Buenos Aires, Argentina).

λlma is based on x64BareBones which is a basic setup to develop operating systems for the Intel 64 bits architecture and a provider of an entry point for a C kernel and the possibility to load extra binary modules separated from the main kernel.

It uses a modification of the Pure64 boot loader to boot up the basic system. The modification enables to load a greater payload than the restrictive 26k that the original allows.

This project needs the following packages: nasm gcc binutils make qemu.

This will install make, build-essential, nasm and qemu into your system.

From the project's directory, run:

sudo apt-get update
sudo apt-get install make build-essential nasm qemu

Or simply run the installation script: ./Scripts/install-linux.sh.

Assuming you already have homebrew installed...

This will install nasm, qemu and a cross compiler (CrossGCC) into your system.

From the project's directory, run:

brew update
brew install nasm
brew install qemu
curl -o gcc-4.8.1-OSX64.dmg http://crossgcc.rts-software.org/download/gcc-4.8.1-for-linux32-linux64/gcc-4.8.1-for-linux64.dmg
hdiutil mount gcc-4.8.1-OSX64.dmg
sudo installer -package /Volumes/gcc-4.8.1-for-linux64/gcc-4.8.1-for-linux64.pkg -target /
hdiutil detach /Volumes/gcc-4.8.1-for-linux64
rm -f gcc-4.8.1-OSX64.dmg

Or simply run the installation script: ./Scripts/install-osx.sh.

From the project's directory, simply run:

make all

If you want to just build the project, run make build then use make run to run.
