LOSS (Lua Operating SystemS)

Aim: To be able to run many virtual kernels built to run Lua.

Currently LOSS shouldn't require anything other than clang and libncurses which doesn't always come pre-installed for all distros.

sudo apt-get install clang libncurses5-dev libboost-system1.62-dev libboost-context1.62-dev libboost-coroutine1.62-dev libfuse-dev libsfml-dev libboost1.62-dev cmake

Building should be as simple as calling

mkdir build
cmake ..
make
./LossProg <name of harddrive file>

Unit testing is as simple as

make TESTING=yes
./LossTests

FUSE tool Todo: Extend tool to be able to create empty harddrives.

./LossFuse -d <name of harddrive file> <mount folder>

• A modified version of lua using boost coroutines to support pre-emptive multitasking.
• Mostly supports and has a concept of multiple processes.
• Supports a VFS (virtual filesystem). So everything starts up in a RAMFS and then harddrives are mounted.
• Uses CMake and generally seems to work across different platforms.

• Not really stable.
• Fuse tool has some strange issues overriding files.
• Has more dependancies than it really needs to build.

[ SUCCESS ] Setup VFS
[ SUCCESS ] Created root user
[ SUCCESS ] Created kernel process
[ SUCCESS ] Created proc filesystem
Booting system from init.d
