Honey os is an open suorce operating system and kernel.
The ´dependencies´ file contains a list of AUR packages that should be installed when runnung Honey-OS. To install them all, use your package manager (paru in this example) like this:
cat dependencies | paru -S -
To build the OS and run in an emulator, run
make
Sometime when modifying hlib, things can break. In this event, clear all build files using
make clean
and try building honey-os again.
The rootfs
directory contains all files for the 'root file system' of the final iso. It contains the final honey os kernel executable file as well as necessary grub configuration files.
The initrd
directory will be created during the building process as a temporary directory. This is later packed into a .tar
file and will be loaded by grub. After booting, the kernel will be able to load additional user mode programs from this 'initial ramdisk', before other file system drivers have been initialized to load programs from the boot drive.
src/kernel
contains all files which are compiled into the finished kernel.
src/userland
contains several directories with source files to compile different ELF user programs. The Makefile at src/userland/Makefile
and the accompanying src/userland/link.ld
are the default method of building the userland files. The compiled binary will have the same name as the folder its source files are located in, so source files in src/userland/shell/
will all be compiled and linked into an ELF file at initrd/shell
, then packed into rootfs/initrd.tar
and then inserted into the .iso
file.
All userspace programms are currently loaded into the virtual address 0x80000000
by default, but honey-os principally supports loading them anywhenre.
The compiled object files for userland programs are stored in src/userland/build/
src/hlib
is the honey OS utility library. It is linked by default with all loaded user mode programs at a high memory address (0xFF000000). And can be linked with and assumed to be loaded by any other program, because it will be loaded first.
src/include
has some .h
that are shared by all userspace programs and supported by hlib.
