Requirements

This target is cross-compiled. There is currently no support for std yet. It generates binaries in the ELF format. Currently, we support the x86_64, aarch64 and riscv64gc architectures. The examples below $ARCH should be substituted for one of the supported architectures.

Building the target

Managarm has upstream support in LLVM since the release of 21.1.0.

Set up your bootstrap.toml like this:

change-id = 142379

[llvm]
targets = "X86;AArch64;RISCV"
download-ci-llvm = false

[build]
target = ["$ARCH-unknown-managarm-mlibc", "x86_64-unknown-linux-gnu"]

[target.x86_64-unknown-linux-gnu]
llvm-config = "/path/to/your/llvm/bin/llvm-config"

[target.$ARCH-unknown-managarm-mlibc]
llvm-config = "/path/to/your/llvm/bin/llvm-config"

Building Rust programs

Build a $ARCH-managarm-gcc using our gcc fork.

[build]
rustc = "/path/to/the/rust-prefix/bin/rustc"
target = "$ARCH-unknown-managarm-mlibc"

[target.$ARCH-unknown-managarm-mlibc]
linker = "/path/to/the/managarm-gcc/bin/$ARCH-managarm-gcc"

Testing

This target does not support running the Rust testsuite yet.
