Summary

Two target systems as base packages for mcpp (design 2026-11-10 E5, E9): each archive is target code (one archive for every host, one sha256 across linux/macosx/windows) and carries an mcpp.toml base statement — the layers it supplies and, per architecture, the directory that is the sysroot.

Package Version Source Contents Size
mingw-w64-sysroot 20261104 official llvm-mingw 20261104 release (UCRT; LLVM 23.1.5) MinGW-w64 headers and import libraries, libc++, libunwind, compiler-rt, libc++'s std module; x86_64 and aarch64 22 MB
freebsd-sysroot 14.5 official FreeBSD 14.5-RELEASE base.txz (amd64, arm64; digests match the release MANIFEST) usr/include, shared libraries, ld-elf.so.1, crt objects, static archives of libc / C++ run-time / compiler run-time; std module sources generated from the official libcxx 21.1.8 source release 40 MB

mingw-w64-sysroot is named with -sysroot because mingw-w64 is the winlibs toolchain on Windows hosts. Release storage: xlings-res/mingw-w64-sysroot, xlings-res/freebsd-sysroot on GitHub, mirrored to GitCode (both downloads verified byte-identical by sha256). The assembly scripts are in .agents/tools/ (build-mingw-w64-sysroot.py, build-freebsd-sysroot.py, libcxx-modules.py); each archive's PROVENANCE.md names the upstream archives and their sha256.

Consumers: mcpp's mingw-llvm provider (Windows GNU-ABI rows from every host, mcpp#913) names xim:mingw-w64-sysroot@20261104; a FreeBSD platform names xim:[email protected].

Test plan

  • Static and isolation tests of both packages (22 passed locally); install/verify tests run in CI (the local sandbox refuses xlings config --add-xpkg for every package).
  • mingw-w64-sysroot with clang 23.1.3: import std programs for x86_64 (runs under wine, static, UCRT imports only) and aarch64.
  • freebsd-sysroot with clang 23.1.3: import std + exceptions for amd64 and arm64, dynamic and static; the amd64 programs run in a FreeBSD 14.5 VM.
  • CI: run 42691990812 green — install (linux, macosx, windows) installs, checks and removes both packages; static/isolation, index-registration, scan, required.

Sorry, something went wrong.

…get systems as mcpp base packages

mingw-w64-sysroot is the target side of llvm-mingw 20261104 (MinGW-w64 on
UCRT, libc++, libunwind, compiler-rt, libc++'s std module) for x86_64 and
aarch64; freebsd-sysroot is FreeBSD 14.5-RELEASE's base system for compiling
and linking (amd64, arm64) with libc++ 21.1.8's std module sources generated
from the official libcxx source release. Each archive is target code, one for
every host, and carries an mcpp.toml base statement (mcpp design 2026-11-10
E5, E9). The assembly scripts are under .agents/tools.

Self-review before merge (spec / ecosystem / architecture / code quality):

  • Spec: both archives carry the E5 base statement exactly as mcpp reads it ([base] roots, include-dirs, libs, std-module, and compiler-runtime-dir for the MinGW base). The mcpp branch builds against the extracted archives: import std on x86_64/aarch64 Windows and FreeBSD, dynamic and static; FreeBSD programs run in a 14.5 VM, Windows ones under wine.
  • Ecosystem: the packages are target code. Each has one archive and one sha256 for every host, and an umbrella xvm node only, so no target header enters a subos sysroot. Release storage is xlings-res on GitHub plus a GitCode mirror verified byte-identical. The packages have no ci block because a version bump re-runs the assembly script.
  • Provenance: the upstream archives are official (llvm-mingw release; FreeBSD base.txz, whose digests equal the release MANIFEST; libcxx 21.1.8 source release). PROVENANCE.md in each archive names them with their sha256. The published archives name the scripts by their working names (mingw_w64_sysroot.py, freebsd_sysroot.py); the scripts' docstrings say so.
  • Code: install() asserts the files whose absence makes the base unusable, for both architectures. The tests assert one hash, no subos publication, and that [base] roots names directories holding the std module sources.
