# Algorithms-c

This subproject contains all C Code for the benchmarking. It is built with
[ceedling](https://www.throwtheswitch.org/ceedling), a more modern build tool
for C projects that also integrates well with the Unity framework.

## Compiler

To compile for STM32, you need to crosscompile

```
# apt install binutils-arm-none-eabi gcc-arm-none-eabi
```

Then, use your tool with an `arm-none-eabi-` prefix: `arm-none-eabi-gcc`. This
project has been configured to use the compiler specified in `$CC` to compile modules and `$AR` to
"link" the object files (this should be `ar` for a static library like this).

```bash
# compile for STM32
CC=arm-none-eabi-gcc AR=arm-none-eabi-ar ceedling release
# compile for this computer
CC=gcc AR=ar ceedling release
```
