Complete from-scratch Linux distribution targeting AMD Ryzen 9 9950X3D + NVIDIA RTX 5090 on ASUS ROG CROSSHAIR X870E HERO. Deliverables: - dpack: custom package manager in Rust (3,800 lines) - TOML package parser, dependency resolver, build sandbox - CRUX Pkgfile and Gentoo ebuild converters - Shared library conflict detection - 124 package definitions across 4 repos (core/extra/desktop/gaming) - 34 toolchain bootstrap scripts (LFS 13.0 adapted for Zen 5) - Linux 6.19.8 kernel config (hardware-specific, fully commented) - SysVinit init system with rc.d service scripts - Live ISO builder (UEFI-only, squashfs+xorriso) - Interactive installer (GPT partitioning, EFISTUB boot) - Integration test checklist (docs/TESTING.md) No systemd. No bootloader. No display manager. Kernel boots via EFISTUB → auto-login → dwl Wayland compositor. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# DarkForge Linux — Phase 0, Chapter 5: GCC Pass 1
|
|
# ============================================================================
|
|
# Purpose: Build the cross-compiler (GCC) as the second component of the
|
|
# cross-toolchain. This produces a C/C++ compiler that runs on the
|
|
# host but generates code for the target (x86_64-darkforge-linux-gnu).
|
|
# No hardware-specific flags (-march=znver5) yet — those come later
|
|
# when we have a native compiler.
|
|
# Inputs: ${LFS}/sources/gcc-15.2.0.tar.xz, mpfr, gmp, mpc tarballs
|
|
# Outputs: Cross-GCC installed to ${LFS}/tools/
|
|
# Assumes: Binutils Pass 1 complete, running as 'lfs' user
|
|
# Ref: LFS 13.0 §5.3
|
|
# ============================================================================
