relibc is a portable POSIX C standard library written in Rust. It is under heavy development, and currently supports Redox and Linux.
The motivation for this project is twofold: Reduce issues the redox crew was having with newlib, and create a safer alternative to a C standard library written in C. It is mainly designed to be used under redox, as an alternative to newlib, but it also supports linux syscalls via the [sc](https://crates.io/crates/sc) crate.

-`src/header/*` - Each folder has a `cbindgen.toml` file, it generates a C-to-Rust interface and header files
-`src/ld_so` - Dynamic loader code
-`src/platform` - Platform-specific and common code
-`src/platform/redox` - Redox-specific code
-`src/platform/linux` - Linux-specific code
-`src/pthread` - pthread implementation
-`src/sync` - Synchronization primitives
-`tests` - C tests (each MR needs to give success in all of them)
### Build On The Build System
Inside of your Redox build system, run:
```sh
make prefix
```
## Building
Just run `make all`.
(It only works if the timestamp of the `relibc` folder changed)
### Issues
#### I'm building for my own platform which I run, and am getting `x86_64-linux-gnu-ar: command not found` (or similar)
The Makefile expects the gnu compiler tools prefixed with the platform specifier, as would be present when you'd install a cross compiler. Since you are building for your own platform, some distros (like Manjaro) don't install/symlink the prefixed executables.

An easy fix would be to replace the corresponding lines in the Makefile, e.g.
```diff
ifeq ($(TARGET),x86_64-unknown-linux-gnu)
export CC=x86_64-linux-gnu-gcc
