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:

sudo apt remove libsodium-dev

1. 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:

cd $HOME/git

1. To download Cardano Node source code, type:

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

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

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

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.

1. 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:

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

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

cabal build all
cabal build cardano-cli

Depending on the processing power of your computer, the build process requires about 20 minutes to complete.

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

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

1. To confirm that the version installed on your computer matches the latest release available in the Cardano Node GitHub repository, type:

cardano-node --version
cardano-cli --version

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