See "Bootstrapping Racket" in the commentary on "racket.scm" for ;; details on the Racket portion of Chez Scheme's bootstrapping path. ;; ;; Chez Scheme is a self-hosting compiler. A small kernel implemented in C ;; loads "boot files" (in a custom object file format) compiled from the parts ;; of the system implemented in Chez Scheme. (While Chez Scheme generates ;; native machine code, it implements its own linker and loader.) ;; ;; As of Chez Scheme 10.0.0 (and the pre-release versions that preceded it on ;; the Racket branch), there are several ways to obtain boot files: ;; ;; 1. The Racket package "cs-bootstrap" (in the "racket/src/rktboot/" ;; directory of the main Racket Git repository) simulates enough of Chez ;; Scheme to load the Chez Scheme compiler purely from source into Racket ;; and apply the compiler to itself, producing the needed boot files ;; (albeit very slowly). ;; Any variant of Racket since version 7.1 can run the simulation. Using ;; the older Racket BC implementation, which does not depend on Chez ;; Scheme, breaks the dependency cycle. ;; However, the simulation relies on implementation details of Chez ;; Scheme, so a given version of Chez Scheme can only be bootstrapped by ;; the corresponding version of the "cs-bootstrap" package. ;; ;; 2. The Chez Scheme makefile provides a "re.boot" target for bootstrapping ;; via a different version of Chez Scheme (9.5.4 or later). ;; This path manages potential differences in implementation details ;; acro
