Ensure your system meets the following requirements:

Operating System must be one of the following:

Configurations

Setup Environment Variables

Use which go to check where Golang is installed

In your .bashrc or .zshrc file, set up environment variables as below:

export GOPATH="folder for all your Golang project"
export PATH=$PATH:$GOPATH/bin
export GO111MODULE=auto
export GOROOT="folder where Golang is installed"
export OLROOT="$GOPATH/src/github.com/Oneledger"
export OLTEST="$OLROOT/protocol/node/scripts"
export OLSCRIPT="$OLROOT/protocol/node/scripts"
export OLSETUP="$OLROOT/protocol/node/setup"
export OLDATA="$GOPATH/test"

and source it(choose .bashrc or .zshrc that you are using)

source ~/.bashrc

Install ClevelDB

For Ubuntu:

sudo apt-get update
sudo apt install build-essential

sudo apt-get install libsnappy-dev

wget https://github.com/google/leveldb/archive/v1.20.tar.gz && \
  tar -zxvf v1.20.tar.gz && \
  cd leveldb-1.20/ && \
  make && \
  sudo cp -r out-static/lib* out-shared/lib* /usr/local/lib/ && \
  cd include/ && \
  sudo cp -r leveldb /usr/local/include/ && \
  sudo ldconfig && \
  rm -f v1.20.tar.gz

For MacOS:

brew install leveldb

Clone the repo

cd $OLPATH
git clone github.com/Oneledger/protocol

Install the required dependencies

cd ./protocol
git checkout develop
git checkout -b name-of-your-branch
make update
make install_c

If no error occurs, you are good to go.
