# building
|
|
|
|
`git submodule udpate --init`
|
|
|
|
- `nasm` compiles the bootcode
|
|
- `ld` links the bootcode and rust binary
|
|
- `grub-mkrescue` builds the iso (need xorriso and mtools)
|
|
- `xargo` builds rust code
|
|
|
|
See `.travis.yml` to get an ubuntu environment ready
|
|
on archlinux `pacman -S rustup make grub xorriso mtools binutils gcc qemu`
|
|
on voidlinux `xbps-install -S rustup make grub xorriso mtools binutils gcc qemu nasm`
|

|
|
#### rust setup
|
|
|
|
We build on nightly channel because of some cool features not yet in stable.
|
|
We need the rust sources to build with xargo for cross-compiling to custom platform.
|
|
|
|
```
|
|
rustup component add rust-src
|
|
rustup override add nightly
|
|
rustup default nightly
|
|
cargo install xargo
|
|
```
|
|
|
|
# running
|
|
|
|
- `make iso` builds a bootable iso with grub
|
|
- `make qemu` runs the iso,
|
|
- `make qemu-reload` reloads the CD
|
|
|
|
# todo
|
|
|
|
- remove assembly for a pure rust entry point
|
|
- replace grub with something lighter (no bootloader at all with `qemu -kernel` ?)
|
