Mes[0] aims to help create full source bootstrapping for GNU/Linux distributions such as GuixSD[1] as part of the bootstrappable builds[2] effort. It consists of a mutual self-hosting Scheme interpreter written in ~5,000LOC of simple C and a Nyacc-based C compiler written in Scheme. > As I could figure out, GuixSD is a (new) GNU package manager, right? Correct. Guix is the packagage manager, GuixSD (for System Distribution) is GNU's GNU/Linux distribution built around it. > I think you mentioned TCC, scheme, own header files etc. This MesCC compiler comes with three sizes of Mes lib C: libc for building mes.c, libc+tcc for building TCC. Then, there is libc+gnu that is used together with TCC to build binutils-2.20a and gcc-2.95.3. > Did you still had to use also the old gcc 2.95.3 ? We are using gcc 2.95.3 as the first GCC compiler mainly because (after many experiments with versions from 1.40 to 4.1) it proved the most "bootstrappable" GCC. GCC 3 introduces a dependency on dirent, e.g., that our naive C library does not support. If we make our libc+gnu richer then we can probably target a newer GCC, but it's not obvious to me what the bootstrap consequences of that are. > What's the goal, and why especially that target version gcc 4.7.4 ? GCC 4.7.4 is currently used as one of the bootstrap binaries of GuixSD. Also, it's the most recent GCC compiler that can be considered to be directly bootstrappable. I don't consider building a c++ bootstrap compiler ;-) The goal is to replace the x86 bootstrap of GNU/Linux distributions, using a bootstrap [mostly] from source instead of what currently happens: seeding it with a very large blob of bootstrap binaries. GuixSD seems the best place to develop this in. > Just a little bit curious about your complicated looking project :-) Thanks for showing interest!
