Building

Environment

• Rust toolchain at nightly-2019-02-16
• Cargo tools: cargo-xbuild
• QEMU >= 3.1.0
• bootimage (for x86_64)
• RISCV64 GNU toolchain (for riscv32/64)
• AArch64 GNU toolchain (for aarch64)
• musl-cross-make (for userland musl, or download prebuilt toolchain from musl.cc)
• libfuse-dev (for userland image generation)

See Travis script for details.

How to run

$ rustup component add rust-src
$ cargo install cargo-xbuild bootimage

$ git clone https://github.com/rcore-os/rCore.git --recursive
$ cd rCore/user
$ make sfsimg arch={riscv32,riscv64,x86_64,aarch64} # requires x86_64-linux-musl-gcc or musl-gcc
$ cd ../kernel
$ make run arch={riscv32,riscv64,x86_64,aarch64} 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
