libhermit-rs is the kernel of the RustyHermit unikernel project.
Usually the kernel will be linked as static library to your applications.
- Rust applications: Instructions can be found in the rusty-hermit repository.
- For C/C++ applications: Instructions can be found in the hermit-playground repository.
If this does not fit your needs and you want to build the kernel as static library to link afterwards, you need the following:
The Rust nightly toolchain (official webpage), the source code of the Rust runtime, and llvm-tools:
rustup toolchain install nightly rustup component add rust-src llvm-tools-preview
You can then build
libhermit-rs with the following command
cargo build -Z build-std=core,alloc,panic_abort --target x86_64-unknown-hermit-kernel
The resulting library then can be found in
libhermit-rs uses the lightweight logging crate log to print kernel messages.
The environment variable
HERMIT_LOG_LEVEL_FILTER controls the verbosity.
You can change it by setting it at compile time to a string matching the name of a LevelFilter.
If the variable is not set, or the name doesn't match, then
LevelFilter::Info is used by default.
$ HERMIT_LOG_LEVEL_FILTER=Debug cargo build -Z build-std=core,alloc,panic_abort --target x86_64-unknown-hermit-kernel
libhermit-rs is derived from following tutorials and software distributions:
- Philipp Oppermann's excellent series of blog posts.
- Erik Kidd's toyos-rs, which is an extension of Philipp Opermann's kernel.
- The Rust-based teaching operating system eduOS-rs.
