DepthOS

Stable, flexible and very simple in use Operating System, which doesn't restrict you

Dependencies

DepthOS requires GNU Make, GCC and NASM to build. And QEMU to run.

Build

Custom toolchain can be configured through environment variables:

• BINCPATH - Root directory of GCC and GNU binutils (defaults to /bin)
• CC - Custom C compiler (defaults to $BINCPATH/gcc)
• LD - Custom linker (defaults to $BINCPATH/ld)

Kernel

To just build the kernel, run make build. If you also want to test it, run just make instead.

Applications

All applications can be build using make apps.

However, each application has it's build system, and might require additional configuration. See application's README for more details

If you weren't using make apps, you would need to manually install applications into initrd/ folder (currently DepthOS supports only the initrd filesystem) and then rebuild the image file with make initrd.

To install the applications manually, you can go into apps/ directory and execute make install there. If you only want to install a particular application, see the it's README for details.

Running

To run DepthOS you can use QEMU's kernel and initrd flags:

qemu-system-i686 -kernel DepthOS-1.0 -initrd initrd.img

ISO

To build an ISO you would first need to install all the binaries into iso/ folder, that can be done by executing make iso.

After that you can use grub-mkrescue to build the ISO itself:

grub-mkrescue -o DepthOS.iso iso/

And run it with QEMU or any other emulator:

qemu-system-i686 DepthOS.iso
