Crystal is a young compiled programming language that is similar to Ruby in syntax but is much faster. It is non-trivial to install Crystal without the root permision. Although you can find precompiled binary packages from Crystal's release page, those packages lack essential libraries required to compile any Crystal programs. As a result, users have to install additional packages to make Crystal work.
This repository provides portable precompiled Crystal binaries. The only
difference from the official packages is that pacakges here include static
libevent and PCRE libraries available in
crystal-libs-v1.tar.bz2 from this repo. To use PortableCrystal, users
can download a package from the release page, unpack it and run
crystal-verion_x64-linux/bin/crystal to compile their programs without
installing other libraries. More importantly, executables compiled with our
binary distributions are not dynamically linked to the two libraries and are
thus more portable -- as developers, we wouldn't want our users to install
other libraries to use our tools.
At present, this repository does not provide libyaml and libgmp which are required to compile certain crystal programs.
