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.
## Building
Just run `make all`.
### 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
- export LD=x86_64-linux-gnu-ld
- export AR=x86_64-linux-gnu-ar
+ export LD=ld
+ export AR=ar
export OBJCOPY=x86_64-linux-gnu-objcopy
endif
```
