crabc-0.1.0 is not a library.

crabc

A Rust musl-compatible libc with a dynamic linker that runs existing, unmodified musl-linked x86_64 Linux binaries.

Requirements

Rust nightly
musl-gcc (from musl-tools / musl-dev)

Build

cargo build --workspace

This produces:

target/debug/libc.so
target/debug/libldso.so
target/debug/loader

Test

Run all integration tests:

cargo test --workspace

Run a single subsystem:

cargo test --test math
cargo test --test ctype
cargo test --test string
cargo test --test ldso_real_binary

Run the upstream musl libc-test harness:

cd libc-test-harness
./run.sh              # functional subset
./run.sh math         # math subset
./run.sh regression   # regression subset
./run.sh api          # API/header checks
./run.sh all          # everything

Project layout

Path	Description
`src/`	`loader` binary — minimal static-PIE ELF runner
`libc/`	`libc.so` / `libc.a` — `no_std` libc implementation
`ldso/`	`libldso.so` — dynamic linker
`include/`	Public C headers
`tests/`	Rust integration tests and C fixtures
`libc-test-harness/`	Shell harness for upstream musl `libc-test`

Notes

long double ABI is currently 64-bit; math fixtures are compiled with -mlong-double-64.
tests/new_functions.rs may fail in containers where /dev/null is a regular file instead of a character device.
libc-test reports many BUILDERRORs until the full musl symbol set is exported; this is expected.
