This repository contains Github Actions workflows and build scripts that build each SBCL release with a few extra "goodies" statically linked into the SBCL runtime: OpenSSL and libfixposix. These two libraries are often cited as a reason why distributing Common Lisp binaries is difficult, so it's useful to have them built into the core.
src/runtime/sbcl is statically linked to libcrypto, libssl, libtls and libfixposix*features*: :CL+SSL-FOREIGN-LIBS-ALREADY-LOADEDCL:LISP-IMPLEMENTATION-VERSION returns a string containing the revision, e.g. "2.3.1+r00"third_party/include contains the headers of libfixposixUbuntu 22.04 LTS.
The binaries are linked to the official OpenSSL from the Ubuntu repositories (with security updates), as well as the Linux port of OpenBSD's libtls.
The latest Github release.
The release process publishes both a source and a binary distribution tarball of SBCL. The naming scheme adds a two-digit revision that is increased every time new releases of the "goodies" occur after SBCL upstream makes a new release. When SBCL is released, the revision is reset to "00".
