# Building ocamlrep with Buck2 and Reindeer
Instructions on how to setup a Buck2 build of ocamlrep. More Buck2 information & examples can be found on the [Buck2 website](https://buck2.build/).
## Setup
### Install Buck2
#### Buck2 binary
- Get the latest prebuilt `buck2` binary (and symlink it into '/usr/local/bin').
```bash
wget https://github.com/facebook/buck2/releases/download/latest/buck2-"$PLAT".zst
zstd -d buck2-"$PLAT".zst -o buck2
chmod +x buck2
sudo ln -s "$(pwd)"/buck2 /usr/local/bin/buck2
```
*Valid values for `$PLAT` are `x86_64-unknown-linux-gnu` on Linux, `x86_64-apple-darwin` on x86 macOS and `aarch64-apple-darwin` on ARM macOS.*
#### Buck2 prelude
- Initialize a Buck2 prelude Git submodule.
```bash
git submodule update --init
```
### Reindeer
[Reindeer](https://github.com/facebookincubator/reindeer) is a tool to generate Buck2 rules for Rust crates.
- Install the `reindeer` binary from source (into '~/.cargo/bin').
```bash
cargo install --git https://github.com/facebookincubator/reindeer.git reindeer
```
### OPAM
- Initialize [OPAM](https://opam.ocaml.org/).
```bash
opam init --compiler=5.1.1 --disable-sandboxing -y
eval $(opam env)
```
### Symlink OPAM
- Run the script 'ocaml-setup.sh'.
```bash
./ocaml-setup.sh
```
*Note: The script assumes that [`OPAM_SWITCH_PREFIX`](https://opam.ocaml.org/doc/Manual.html#Switches) is set.*
### Generate BUCK rules for third-party Rust.
- Run `reindeer buckify`.
```bash
reindeer --third-party-dir shim/third-party/rust buckify
```
## Build
- Build the complete set of ocamlrep targets.
```bash
buck2 build root//...
```
