## Code structure
|
|
|
|
Each major component and library has its own subdirectory (kernel, userspace, libc, ...). Each directory contains directory *include*, which has **all** of the header files of the component. Every header is included by its absolute path.
|
|
|
|
## Building
|
|
|
|
### Needed packages
|
|
|
|
#### apt (tested on ubuntu 22.04)
|
|
```# apt install build-essential git ninja-build texinfo bison flex libgmp-dev libmpfr-dev libmpc-dev parted qemu-system-x86```
|
|
|
|
#### pacman
|
|
```# pacman -S --needed base-devel git wget cmake ninja parted qemu-system-x86```
|
|
|
|
|
|
### Compilation
|
|
|
|
To build the toolchain for this os. You can run the following command.
|
|
> ***NOTE:*** The following step has to be done only once. This might take a long time since we are compiling binutils and gcc.
|
|
```sh
|
|
./bos toolchain
|
|
```
|
|
|
|
To build the os itself you can run one of the following commands. You will need root access for disk image creation/modification.
|
|
```sh
|
|
./bos qemu
|
|
./bos qemu-nographic
|
|
./bos qemu-debug
|
|
./bos bochs
|
|
```
|
|
|
|
You can also build the kernel or disk image without running it:
|
|
```sh
|
|
./bos kernel
|
|
./bos image
|
|
```
|
|
|
|
To build for other architectures set environment variable BANAN\_ARCH=*arch* (e.g. BANAN\_ARCH=i686).
|
|
|
|
To change the bootloader you can set environment variable BANAN\_BOOTLOADER; supported values are BANAN (my custom bootloader) and GRUB.
|
|
|
|
To run with UEFI set environment variable BANAN\_UEFI\_BOOT=1. You will also have to set OVMF\_PATH to the correct OVMF (default */usr/share/ovmf/x64/OVMF.fd*).
|
|
|
|
If you have corrupted your disk image or want to create new one, you can either manually delete *build/banan-os.img* and build system will automatically create you a new one or you can run the following command.
|
|
```sh
|
|
./bos image-full
|
|
```
|
|
|
|
I have also created shell completion script for zsh. You can either copy the file in _script/shell-completion/zsh/\_bos_ to _/usr/share/zsh/site-functions/_ or add the _script/shell-completion/zsh_ to your fpath in _.zshrc_.
