Download the ledger code
If you need them, here are the Git SSH key generation instructions.
Clone the repository:
cd [working_directory] git clone https://github.com/fetchai/ledger.git git checkout release/v0.9.x
Update and initialise submodules from the repository root directory:
cd ledger git pull git submodule update --init --recursive
Make sure you have all the submodules:
git submodule status
If any submodules are missing, please check your installation.
Build the ledger
ledger directory, follow the steps to build the library:
mkdir build cd build cmake .. make -j constellation

make -j 4 constellation
If you want, you can build all the libraries:
make -j 4
