# Compiling Contracts

Let's first create a contract

```bash
zeus create contract compiler
```

This places an EOSIO contract in `/contracts/eos`Now let's compile it.

```bash
zeus compile compiler # if using an old cdt --legacy-cdt
```

{% hint style="info" %}
If you want to use docker add `--docker=true`. EOSIO (now leap) and eosio.cdt (now cdt) only supports Ubuntu 18, 22, 24, so Docker must be used for the latest versions
{% endhint %}

If you wanted to compile all contracts within the`./contracts` directory, you can run

{% tabs %}
{% tab title="Compile" %}

```
zeus compile
```

{% endtab %}

{% tab title="Options" %}

```bash
zeus compile [contract]

compile contracts

Options:
  --version       Show version number                                  [boolean]
  --storage-path  path for persistent storage    [default: "/home/ubuntu/.zeus"]
  --rc-file       use rc file to load options from
                                     [default: "/home/ubuntu/.zeus/zeusrc.json"]
  --rc-ignore     ignore rc file                                [default: false]
  --verbose, -v                                                 [default: false]
  -h, --help      Show help                                            [boolean]
  --all           compile all contracts                          [default: true]
  --chain         chain to work on                              [default: "eos"]
  --sidechain     sidechain name to use for liquidx                [default: ""]
  --phase         select compile option [dapp-services-eos, eos]   [default: ""]
  --docker        enable to use docker                          [default: false]
  --legacy-cdt    unbox cmake files using cdt version < 3.0.0   [default: false]

Examples:
  zeus compile --all
  zeus compile helloworld
```

{% endtab %}
{% endtabs %}

To compile an ETH contract run:

{% tabs %}
{% tab title="Zeus" %}

```bash
zeus compile link --phase eth
# to compile all
zeus compile --phase eth
```

{% endtab %}

{% tab title="Truffle" %}

```bash
npx truffle compile
# run any truffle command
```

{% endtab %}
{% endtabs %}

If you wish to add your own ethereum contract, you can place it in the `./contracts/eth` directory.&#x20;

{% hint style="info" %}
If you want to change the compiler version, or any truffle settings, see the `./truffle-config.js` file.
