# Lua OS

A mix of OSKit and Lua.

## Requirements

   

* gcc 4.5+

* scons

* qemu

### ubuntu

    

    $ sudo apt-get install scons # https://launchpad.net/ubuntu/+source/scons

    $ sudo apt-get install qemu # https://help.ubuntu.com/community/Installation/QemuEmulator

    

## Setup

    $ git clone http://github.com/mischief/los

    $ cd los

Run scons

    $ scons

    scons: Reading SConscript files ...

    scons: done reading SConscript files.

    scons: Building targets ...

    scons: building associated VariantDir targets: .build

    as       .build/src/crt/x86/multiboot.o

    src/crt/x86/multiboot.S: Assembler messages:

    src/crt/x86/multiboot.S:33: Error: invalid instruction suffix for `push'

    src/crt/x86/multiboot.S:36: Error: operand type mismatch for `push'

    src/crt/x86/multiboot.S:37: Error: operand type mismatch for `push'

    scons: *** [.build/src/crt/x86/multiboot.o] Error 1

    scons: building terminated because of errors.

Ack! Cross compiling failed. Update build parameters

    $ emacs -nw scache.conf # or vim or whatever editor of your choice

    verbose = True

    

Try again

    # Tips:

    # If you get an error, you can do: scons -c to clean

    # To run a parallel build: scons -j _ (where _ is # of cores, e.g. 1, 2, 4)

    $ scons

    scons: Reading SConscript files ...

    scons: done reading SConscript files.

    scons: Building targets ...

    scons: building associated VariantDir targets: .build

    Copy("kernel", ".build/kernels/hello")

    scons: done building targets.

Mount the disk image to the floppy disk -- Check this file first

before proceeding! Also, if anyone knows how to a modify floppy disks

in userspace without calling mount (which requires root)

    $ ./scripts/update_linux.sh

    Mounting floppy...

    [sudo] password for mek: 

    Copying kernels...

    Unmounting floppy...

## Go!

Run qemu to emulate and run the image

    qemu-system-i386 -fda ./los.img

If, after GRUB, you see a stream of non-stop text, you've encountered an error. This happens if debug settings not included with scons (if optimization level of gcc is set to anything > 0)

    $ scons debug=true optimization=0 # verbose=False (optional)

    $ ./scripts/update_linux.sh

    $ qemu-system-i386 -fda ./los.img

Prefer interacting with los from your custom terminal instead of through qemu?

    qemu-system-i386 -serial stdio -fda ./los.img
