API. It was originally a stripped-down copy of
|
|
|
|
|
[C-KZG](https://github.com/benjaminion/c-kzg), but it has been heavily modified

|
|
|

since then.

|
|
|
|
2023-03-28 13:26:51 +00:00
|
|
|
* `git`
|
|
|
|
|
* `make`
|
|
|
|
|
* `clang`

### Build & test
|
2022-11-04 23:56:16 +00:00
|
|
|
|
2023-03-28 13:26:51 +00:00
|
|
|
To build `c_kzg_4844.o`, the object file that the bindings use, run `make` in
|
|
|
|
|
the `src` directory. This will ensure the `blst` submodule has been initialized,
|
|
|
|
|
build `blst`, build `c_kzg_4844`, and run the tests. From the project root, run
|
|
|
|
|
this:
|
2022-11-04 23:56:16 +00:00
|
|
|
|
|
|
|
|
```
|
2023-03-28 13:26:51 +00:00
|
|
|
cd src && make
|
2022-11-04 23:56:16 +00:00
|
|
|
```
