crabc-libc

A no_std Rust implementation of musl-compatible libc. Produces libc.so and libc.a for running unmodified musl-linked ELF binaries.

Usage

This crate is not intended for direct use as a Rust library. It produces C-compatible shared/static libraries:

• libc.so — dynamic library
• libc.a — static library

Build with:

cargo build -p crabc-libc

Output is in target/debug/libc.so and target/debug/libc.a.

Features

• Implements ~350+ C library functions (stdio, stdlib, string, math, pthread, etc.)
• no_std — no Rust standard library dependency
• Targets musl ABI for x86_64 and aarch64
• Supports long double via f128 on aarch64
