This is the instrucctions I have but it don't make the compile well:

1º) Get dependencies:

sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python \
      zlib1g-dev wget bsdmainutils automake

2º) Install:

git clone https://github.com/zencashio/zen.git

# Build
cd zen
./zcutil/build.sh -j$(1)
# fetch key
./zcutil/fetch-params.sh
# Run
./src/zend
