# Luna
|
||||
A very basic POSIX operating system for desktop computers, written mostly in C++ and C. [](https://drone.cloudapio.eu/apio/Luna)
|
||||
|
||||
## Another UNIX clone?
|
||||
[Yes, another UNIX clone](https://wiki.osdev.org/User:Sortie/Yes_Another_Unix_Clone).
|
||||
A simple kernel and userspace for the x86_64 platform, written mostly in C++ and C.
|
||||
|
||||
## Features
|
||||
- x86_64-compatible lightweight [kernel](kernel/).
|
||||
- x86_64-compatible [kernel](kernel/).
|
||||
- Keeps track of which [memory](kernel/src/memory/) is used and which memory is free, and can allocate memory for itself and [user programs](kernel/src/sys/mem.cpp).
|
||||
- Can read, write and execute files from a [virtual file system](kernel/src/fs/) supporting an initial ramdisk, device pseudo-filesystems... but no hard disks yet.
|
||||
- Preemptive multitasking, with a round-robin [scheduler](kernel/src/thread/) that can switch between tasks.
|
||||
- [Virtual file system](kernel/src/fs/) with a simple but working [tmpfs](kernel/src/fs/tmpfs/) populated from the initial ramdisk.
|
||||
- Can [load ELF programs](kernel/src/ELF.cpp) from the file system as userspace tasks.
|
||||
- [System call](kernel/src/sys/) interface and [C Library](libc/), aiming to be mostly POSIX-compatible.
|
||||
- Designed to be [portable](kernel/src/arch), no need to be restricted to x86_64.
|
||||
- Fully [UTF-8 aware](libluna/include/luna/Utf8.h), **everywhere**.
|
||||
- [Thread](libluna/include/luna/Atomic.h) [safety](kernel/src/thread/Spinlock.h) (supposedly).
|
||||
- Environment-agnostic [utility library](libluna/), which can be used in both kernel and userspace.
|
||||
- Return-oriented [error propagation](libluna/include/luna/Result.h), inspired by Rust and SerenityOS.
|
||||
- Build system uses [CMake](CMakeLists.txt).
|
||||
- Can [load ELF programs](kernel/src/sys/elf/) from the file system as userspace tasks.
|
||||
- [System call](kernel/src/sys/) interface and [C Library](libs/libc/), aiming to be mostly POSIX-compatible.
|
||||
- UNIX-like [multitasking primitives](kernel/src/sys/exec.cpp), which allow user tasks to spawn other tasks.
|
||||
- Some simple [userspace programs](apps/src/), written in C.
|
||||
- Simple [command-line shell](apps/src/sh.c), allowing for interactive use of the system.
|
||||
- Basic multi-user system with [a password file](initrd/etc/passwd) and utilities for [logging in](apps/src/session.c) and [switching users](apps/src/su.c).
|
||||
|
||||
## Notes
|
||||
- The default user is named 'selene' and you can log into it with the password 'moon'.

## Setup
|
||||
|
||||
To build and run Luna, you will need to build a [GCC Cross-Compiler](https://wiki.osdev.org/Why_do_I_need_a_Cross_Compiler) and cross-binutils for `x86_64-luna`. (Yes, Luna is advanced enough that it can use its own [OS-Specific Toolchain](https://wiki.osdev.org/OS_Specific_Toolchain), instead of a bare metal target like `x86_64-elf`. It is the first of my OS projects to be able to do so. The patches for Binutils and GCC are [binutils.patch](tools/binutils.patch) and [gcc.patch](tools/gcc.patch)).

## Building
|
||||
Yes, there is a Makefile sitting on the top level of the repository. It's tempting. But do not use it directly, since it depends on environment variables set by the build scripts.
|

|

There are a variety of scripts for building Luna.

`tools/build.sh` will build the kernel, libc and binaries.

@ -42,11 +42,13 @@ There are a variety of scripts for building Luna.
|
||||
|
||||
`tools/build-iso.sh` will build, install, and make an ISO disk image named Luna.iso.
|
||||
|

`tools/build-debug.sh` will rebuild the kernel with debug symbols and optimizations disabled, install, and make an ISO image. This script should only be used when you are going to be running the system with a debugger (such as GDB).
|
||||
|
||||
`tools/build-stable-iso.sh` does the same thing as build-iso.sh, but configures the kernel so that the version does not show the commit hash (used for stable versions).
|
||||
|
||||
`tools/rebuild-iso.sh` will do a clean rebuild, install, and make an ISO disk image.
|
||||
|
||||
In most cases, you should just use `run.sh`, but if you want to build without running, `build-iso.sh`.

## Running
|

|

@ -54,12 +56,14 @@ You should have [QEMU](https://www.qemu.org/) installed.
|
||||
|
||||
You can choose between 3 run scripts:

`tools/run.sh` is the one you should use in most cases. It will build changed files, install, make an ISO image, and run Luna in QEMU.
|
||||
`tools/run.sh` is the one you should use in most cases. It will build (only files that have changed since last build), install, make an ISO image, and run Luna in QEMU.
|
||||
|
||||
`tools/rebuild-and-run.sh` will rebuild, install, make an ISO, and run Luna in QEMU.
|
||||
|
||||
`tools/debug.sh` will run Luna in QEMU with a port open for GDB to connect to. (run `tools/build-debug.sh`, `tools/gdb.sh`, and then `tools/debug.sh` in a separate terminal for an optimal debugging experience)
|
||||
|
||||
Beware that running with optimizations disabled may cause the kernel to behave differently, which is why I don't use it that often.
|
||||
|
||||
Essentially, since `run.sh` builds the toolchain if it hasn't been built, builds Luna if it hasn't been built, and runs it, you could just checkout this repo, run `run.sh`, and you're done. No need for the other scripts. Those are included for more fine-grained control/building step-by-step.
|
||||
|
||||
You can pass any arguments you want to the run scripts, and those will be forwarded to QEMU. Example: `tools/run.sh -m 512M -net none -machine q35`.

|

## Is there third-party software I can use on Luna?
|
||||
|
||||
Not right now, but hopefully we can start porting some software soon! (After the VFS and fork/exec are done, of course. So, in a long time.)
|
||||
Yes, actually! Check out the [ports](ports/) directory.
|
||||
Right now, there are very few ports, because our C Library is a bit primitive and doesn't support complex projects.
|
||||
|
||||
You should also keep in mind that it is not possible to compile software written in any language other than C/C++ (and C++ was added recently, its standard library doesn't work very well) for Luna right now.
|
||||
|
||||
But feel free to try to port some program yourself and add it to the ports directory!
|
||||
|
||||
Port usage:
|
||||
|
||||
`ports/add-port.sh <port-name>` will build and add a port to the list of installed ports, and the built port will automatically get installed into the system root every time you run Luna.
|
||||
|
||||
`ports/remove-port.sh <port-name>` will remove the port from the list of installed ports, remove built files from the system root, as well as the build directory.
|
||||
|
||||
`ports/make-package.sh <port-name>` will compile the port and make a package archive from it, which may be used in the future with a package manager :)
