These commands set the EOSIO directories, install git, and clone the EOSIO repository.

# set EOSIO directories
export EOSIO_LOCATION=~/eosio/eos
# install git
yum update -y && yum install -y git
# clone EOSIO repository
git clone https://github.com/EOSIO/eos.git $EOSIO_LOCATION
cd $EOSIO_LOCATION && git submodule update --init --recursive

Install EOSIO Dependencies

These commands install the EOSIO software dependencies. Make sure to Download the EOSIO Repository first and set the EOSIO directories.

These commands build the EOSIO software on the specified OS. Make sure to Install EOSIO Dependencies first.

EOSIO_BUILD_LOCATION environment variable

Do NOT change this variable. It is set for convenience only. It should always be set to the build folder within the cloned repository.

cd $EOSIO_BUILD_LOCATION && source /opt/rh/devtoolset-8/enable && cmake -DCMAKE_BUILD_TYPE='Release' -DLLVM_DIR='/opt/rh/llvm-toolset-7.0/root/usr/lib64/cmake/llvm' -DCMAKE_INSTALL_PREFIX=$EOSIO_INSTALL_LOCATION $EOSIO_LOCATION
cd $EOSIO_BUILD_LOCATION && make -j$(nproc)

Install EOSIO
