I fairly sure configure suggests the package that would have to be installed: "Consider installing zlib-dev (zlib-devel, some fio features depend on it. " I think of RPM distros the package that lets you build against zlib is called zlib-devel but I don't know what it is on distros like Arch... > Can you provide steps to compile and build the binary that runs > across different CPU architectures and different OS. Building a single binary that works across multiple different Linux distros is rather out of the scope of this list and is a more general "building for Linux" question. If you choose to go that route (hint: it may not be easy) you generally have to look towards bundling libraries and messing with environment variables/rpath or more likely switching to static linking (see ./configure --help) but then ALL your libraries must be present in static form on the build machine). Even with static linking there are other caveats (you may find you have to build the binary on the oldest OS, you may find trouble static linking glibc and start looking to use musl which will bring different challenges)...
