# Compiling Cardano Node

After you finish installing GHC and Cabal successfully, you can compile Cardano Node from source code.

**To compile Cardano Node:**

1. To ensure that development headers for the `libsodium` cryptographic library are NOT installed on the local computer, type:

```bash
sudo apt remove libsodium-dev
```

2. In a terminal window on the computer hosting your block-producing node, type the following command to navigate to the working directory that you created in the procedure [Installing Glasgow Haskell Compiler and Cabal](/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node/part-i-installation/installing-ghc-and-cabal.md):

```bash
cd $HOME/git
```

3. To download Cardano Node source code, type:

```bash
git clone https://github.com/IntersectMBO/cardano-node.git
cd cardano-node
git fetch --all --recurse-submodules --tags
```

4. To switch the repository that you downloaded to your local computer in step 3 to the latest tagged commit, type:

```bash
git checkout $(curl -s https://api.github.com/repos/IntersectMBO/cardano-node/releases/latest | jq -r .tag_name)
```

{% hint style="info" %}
Typing a dollar sign ("$") before a command in parentheses refers to the output of the command in parentheses. For example, using a Web browser you can navigate to the above URL <https://api.github.com/repos/IntersectMBO/cardano-node/releases/latest> to display the data that the `curl` command retrieves, and then confirm the value of the `tag_name` attribute that the `jq` command selects.
{% endhint %}

5. To adjust the project configuration to disable optimization and set the recommended compiler version, type the following command where `<GHCVersionNumber>` is the GHC version that you set in the procedure [Installing Glasgow Haskell Compiler and Cabal](/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node/part-i-installation/installing-ghc-and-cabal.md):

```bash
cabal update
cabal configure -O0 -w ghc-<GHCVersionNumber>
```

6. To produce executable `cardano-node` and `cardano-cli` binaries, type:

```bash
cabal build all
cabal build cardano-cli

```

{% hint style="info" %}
Depending on the processing power of your computer, the build process requires about 20 minutes to complete.
{% endhint %}

7. To copy the `cardano-node` and `cardano-cli` binaries that you produced in step 6 into the `/usr/local/bin` directory, type:

```bash
sudo cp -p "$(./scripts/bin-path.sh cardano-node)" /usr/local/bin/cardano-node
sudo cp -p "$(./scripts/bin-path.sh cardano-cli)" /usr/local/bin/cardano-cli
```

8. To confirm that the version installed on your computer matches the latest release available in the Cardano Node [GitHub repository](https://github.com/input-output-hk/cardano-node), type:

```bash
cardano-node --version
cardano-cli --version
```

9. On each computer hosting a relay or block-producing node for your stake pool, repeat steps 1 to 8
