Initial commit: DarkForge Linux — Phases 0-12
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 Toolchain Bootstrap
|
||||
|
||||
Cross-compilation toolchain scripts that build the base system from scratch, following the Linux From Scratch (LFS 13.0) methodology with DarkForge-specific customizations.
|
||||
|
||||
## Overview
|
||||
|
||||
These scripts implement LFS Chapters 5-7, adapted for:
|
||||
|
||||
- **Target:** AMD Ryzen 9 9950X3D (Zen 5, `-march=znver5`)
|
||||
- **Compiler:** GCC 15.2.0 (full znver5 support)
|
||||
- **Target triplet:** `x86_64-darkforge-linux-gnu`
|
||||
|
||||
The build produces a self-hosting chroot environment capable of compiling everything else.
|
||||
|
||||
## Requirements
|
||||
|
||||
- A Linux host system (any recent distro)
|
||||
- ~20GB free disk space
|
||||
- Internet access (for downloading sources)
|
||||
- Host tools: bash, gcc, g++, make, bison, gawk, m4, texinfo, xz, wget/curl
|
||||
|
||||
### Host System Verification
|
||||
|
||||
Check your host has the required tools:
|
||||
|
||||
```bash
|
||||
# Verify essential tools are present
|
||||
for cmd in bash gcc g++ make bison gawk m4 texinfo xz wget; do
|
||||
command -v $cmd >/dev/null && echo "OK: $cmd" || echo "MISSING: $cmd"
|
||||
done
|
||||
```
|
||||
|
||||
## Build Process
|
||||
|
||||
### Step 1: Set up the environment
|
||||
|
||||
```bash
|
||||
export LFS=/mnt/darkforge
|
||||
|
||||
# Create and mount your target partition
|
||||
sudo mkdir -pv $LFS
|
||||
sudo mount /dev/nvme0n1p3 $LFS # adjust device as needed
|
||||
|
||||
# Run the environment setup
|
||||
sudo bash scripts/000-env-setup.sh
|
||||
```
|
||||
|
||||
This creates the `lfs` user, directory structure, and environment variables.
|
||||
|
||||
### Step 2: Download sources
|
||||
|
||||
```bash
|
||||
bash scripts/000a-download-sources.sh
|
||||
```
|
||||
|
||||
Downloads all ~30 source tarballs to `$LFS/sources/`.
|
||||
|
||||
### Step 3: Build the cross-toolchain (Chapter 5)
|
||||
|
||||
```bash
|
||||
bash scripts/build-all.sh cross
|
||||
```
|
||||
|
||||
Builds: binutils (pass 1) → GCC (pass 1) → Linux headers → glibc → libstdc++
|
||||
|
||||
### Step 4: Build temporary tools (Chapter 6)
|
||||
|
||||
```bash
|
||||
bash scripts/build-all.sh temp
|
||||
```
|
||||
|
||||
Builds 17 packages: m4, ncurses, bash, coreutils, diffutils, file, findutils, gawk, grep, gzip, make, patch, sed, tar, xz, binutils (pass 2), GCC (pass 2).
|
||||
|
||||
### Step 5: Enter chroot and build native tools (Chapter 7)
|
||||
|
||||
```bash
|
||||
sudo bash scripts/023-chroot-setup.sh
|
||||
# Now inside the chroot:
|
||||
bash /sources/toolchain-scripts/024-chroot-essentials.sh
|
||||
bash /sources/toolchain-scripts/025-gettext.sh
|
||||
# ... through 030-util-linux.sh
|
||||
bash /sources/toolchain-scripts/031-cleanup.sh
|
||||
```
|
||||
|
||||
### Step 6: Verify
|
||||
|
||||
The cleanup script runs a "Hello World" compilation test. If it passes, the toolchain is ready.

## Version Manifest
|
||||
|
||||
See `VERSION_MANIFEST.md` for the exact version of every package used, with source URLs and rationale.
|
||||
|
||||
## Logs
|
||||
|
||||
Build logs are saved to `logs/<script-name>.log` by the master build runner.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
If a build fails:
|
||||
|
||||
1. Check the log file in `logs/`
|
||||
2. The most common issue is a missing host dependency
|
||||
3. The glibc sanity checks (script 004) are critical — if they fail, the entire toolchain is broken
|
||||
4. GCC pass 1 is the longest build (~4 SBU on the 9950X3D with `-j32`)
|
||||
