Quick and dirty: download Makefile and source code from github

(pre-requisite: working C++ compiler like g++ or clang, make, wget)

wget https://github.com/fcorbelli/zpaqfranz/raw/main/zpaqfranz.cpp
wget https://github.com/fcorbelli/zpaqfranz/raw/main/NONWINDOWS/Makefile
make install clean

Dirtiest (!), the "nightly build"

(pre-requisite: working C++ compiler like g++ or clang, wget, NO MAKE NEEDED)

WARNING This version is the n-1, may (will) contain experimental code, compilation incompatibilities etc. Almost the bleeding edge

wget http://www.francocorbelli.it/zpaqfranz.cpp -O zpaqfranz.cpp

then... build (aka: compile)
