## Building

### Environment

* [Rust](https://www.rust-lang.org) toolchain at nightly-2019-03-05
* Cargo tools: [cargo-xbuild](https://github.com/rust-osdev/cargo-xbuild)
* [QEMU](https://www.qemu.org) >= 3.1.0
* [bootimage](https://github.com/rust-osdev/bootimage) (for x86_64)
* [RISCV64 GNU toolchain](https://www.sifive.com/boards) (for riscv32/64)
* [AArch64 GNU toolchain](https://cs140e.sergio.bz/assignments/0-blinky/) (for aarch64)
* [musl-cross-make](https://github.com/richfelker/musl-cross-make) (for userland musl, or download prebuilt toolchain from [musl.cc](https://musl.cc/))
* [libfuse-dev](https://github.com/libfuse/libfuse) (for userland image generation)

See [Travis script](./.travis.yml) for details.

### How to run

```bash
$ rustup component add rust-src llvm-tools-preview
$ cargo install cargo-binutils
$ cargo install cargo-xbuild --force
$ cargo install bootimage --version 0.5.7 --force
```

```bash
$ git clone https://github.com/rcore-os/rCore.git --recursive
$ cd rCore/user
$ make sfsimg arch={riscv32,riscv64,x86_64,aarch64,mipsel} # requires $(arch)-linux-musl-gcc
$ cd ../kernel
$ make run arch={riscv32,riscv64,x86_64,aarch64,mipsel} mode=release
$ make run arch=x86_64 mode=release pci_passthru=0000:00:00.1 # for ixgbe real nic, find its pci (bus, dev, func) first
```
