# Red Bear OS Build Tools Porting Plan
|
||||
|
||||
**Status:** Phases 1-2 complete (2026-05-07)
|
||||
**Goal:** Enable native compilation inside Red Bear OS — `./configure && make` producing
|
||||
x86_64-unknown-redox binaries from within the target OS itself.
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Red Bear OS currently has a **fully functional cross-compilation toolchain** (GCC 13.2.0,
|
||||
LLVM 21, Rust nightly-2025-10-03) running on the Linux build host. These produce
|
||||
x86_64-unknown-redox binaries that are packaged and installed into the OS image.
|
||||
|
||||
**There is no native build environment inside Red Bear OS.** You cannot run `./configure`,
|
||||
`make`, `cmake`, or `cargo build` inside the target OS. To enable `cub build` (recipe
|
||||
cooking) inside Red Bear OS as envisioned in the cub redesign, all build tools must be
|
||||
ported to run natively on x86_64-unknown-redox.
|
||||
|
||||
This document assesses the current state, identifies the critical path, and provides a
|
||||
phased implementation plan.
|
||||
|
||||
## Current State Inventory
|
||||
|
||||
### Cross-Compiler Toolchain (Host → Target)
|
||||
|
||||
```
|
||||
prefix/x86_64-unknown-redox/
|
||||
├── gcc-install/ ← GCC 13.2.0 cross-compiler (host → redox)
|
||||
├── clang-install/ ← LLVM 21 cross-compiler
|
||||
├── rust-install/ ← Rust nightly cross-compiler
|
||||
├── relibc-install/ ← relibc headers + libraries
|
||||
└── sysroot/ ← Target sysroot (/usr)
|
||||
```
|
||||
|
||||
These compilers **run on the Linux host** and produce redox binaries. They are NOT
|
||||
usable inside Red Bear OS itself.
|
||||
|
||||
### Build Tool Recipe Inventory
|
||||
|
||||
Of 47 build-tool recipes in the codebase:
|
||||
|
||||
| Status | Count | Description |
|
||||
|--------|-------|-------------|
|
||||
| ✅ Production | 25 | Build and work |
|
||||
| 🚧 WIP/Partially tested | 6 | Build but not validated |
|
||||
| ❌ TODO/Broken | 16 | Recipe exists but doesn't compile |
|
||||
|
||||
### What Already Exists (Production-Ready)
|
||||
|
||||
| Category | Tools |
|
||||
|----------|-------|
|
||||
| Shell | bash, zsh, dash, ion |
|
||||
| Core utils | coreutils (Rust), findutils (Rust), ripgrep, gnu-grep, sed |
|
||||
| File tools | patch, grep, sed |
|
||||
| Archives | bzip2, xz, zstd, lz4 |
|
||||
| Scripting | python312, lua54 |
|
||||
| Build systems | gnu-make, cmake 4.0.3, autoconf, automake, pkg-config |
|
||||
| Compilers (cross) | gcc13, llvm21, rust |
|
||||
| VCS | git (v2.13.1, old) |
|
||||
|
||||
### What's Missing or Broken (Critical Gaps)
|
||||
|
||||
| Gap | Severity | Impact |
|
||||
|-----|----------|--------|
|
||||
| **No `tar`** | ⚠️ Critical | `./configure` scripts need tar extraction |
|
||||
| **No `procps` (ps, kill)** | ⚠️ Critical | Build job control |
|
||||
| **No `m4`** | ⚠️ Critical | Autotools macro processor |
|
||||
| **No `meson`/`ninja`** | ⚠️ High | Qt, systemd, many libs use meson |
|
||||
| **No `flex`/`bison`** | ⚠️ High | Parser generators for gcc, binutils, many pkgs |
|
||||
| **`diffutils` suppressed** | Medium | gnulib/relibc header conflict in mini target |
|
||||
| **`mkfifo` disabled** | Medium | `make -jN` parallel jobserver needs named pipes |
|
||||
| **`perl5` WIP** | Medium | Autoconf/automake need perl for regeneration |
|
||||
| **`texinfo` broken** | Low | Documentation generation |
|
||||
| **`ruby` broken** | Low | Ruby ecosystem tools |
|
||||
|
||||
### POSIX Substrate Status (relibc)
|
||||
|
||||
Key build-tool-relevant POSIX functions:
|
||||
|
||||
| Function | Status | Impact |
|
||||
|----------|--------|--------|
|
||||
| `fork`/`exec` | ✅ Working | Process spawning |
|
||||
| `pipe` | ✅ Working | IPC |
|
||||
| `mmap` | ✅ Working | Memory mapping |
|
||||
| `eventfd` | ✅ Implemented | Event notification |
|
||||
| `signalfd` | 🚧 Partial | Signal delivery via fd (read path unverified) |
|
||||
| `sem_open`/`close` | ✅ Implemented | Named semaphores |
|
||||
| `shm_open` | ✅ Working | Shared memory |
|
||||
| `waitid` | ✅ Implemented | Process reaping |
|
||||
| `mkfifo` | ❌ Disabled | Named pipes — `make -j` jobserver blocked |
|
||||
| `times()` | ❌ Missing | zsh `times` builtin stubbed |
|
||||
| `getrlimit`/`setrlimit` | ✅ Implemented | Resource limits |
|
||||
|
||||
The POSIX substrate is **mostly adequate** for build tools. The critical gap is `mkfifo`
|
||||
(named pipes), which blocks GNU Make's parallel jobserver. Single-threaded `make` works.
|
||||
|
||||
## Why Port Build Tools? (Motivation)
|
||||
|
||||
The cub package manager redesign envisions `cub build` running inside Red Bear OS:
|
||||
```
|
||||
User runs: cub -S some-pkg # Search AUR, fetch PKGBUILD
|
||||
cub -G some-pkg # Convert to recipe.toml → ~/.cub/
|
||||
cub -B some-pkg # BUILD inside Red Bear OS → install
|
||||
```
|
||||
|
||||
Without native build tools, step 3 (`cub -B`) requires the host build toolchain, which
|
||||
doesn't exist inside Red Bear OS. Until tools are ported, `cub` can only:
|
||||
- Search AUR and fetch/convert PKGBUILDs
|
||||
- Install pre-built pkgar packages (transferred from a build host)
|
||||
- Manage the ~/.cub/ package database
|
||||
|
||||
Full `cub build` functionality requires native compilation capability.
|
||||
|
||||
## Dependency Graph
|
||||
|
||||
### Critical Path Chain (Bootstrap Order)
|
||||
|
||||
```
|
||||
Level 0: Already available
|
||||
├── bash, zsh, sed, grep, coreutils, findutils, patch, diffutils (in full)
|
||||
├── python312, lua54
|
||||
├── bzip2, xz, zstd, lz4
|
||||
└── pkg-config
|
||||
|
||||
Level 1: Prerequisite tools (need Level 0 to build)
|
||||
├── m4 ← needs: configure (uses Level 0)
|
||||
├── perl5 ← needs: configure + relibc siginfo fixes
|
||||
├── tar ← needs: cargo build (uutils-tar) or configure (GNU tar)
|
||||
├── flex ← needs: configure + m4 + bison (circular!)
|
||||
└── bison ← needs: configure + m4 + flex (circular!)
|
||||
|
||||
Level 2: Build systems (need Level 0-1)
|
||||
├── gnu-make ← already production (needs mkfifo fix for -jN)
|
||||
├── autoconf ← already production
|
||||
├── automake ← already production
|
||||
├── libtool ← already builds (needs testing)
|
||||
├── meson ← needs: python312 + standalone script
|
||||
└── ninja ← needs: cmake or python configure.py
|
||||
|
||||
Level 3: Native compilers (need Level 0-2 + cross-compiler bootstrap)
|
||||
├── gcc-native ← needs: cross-gcc bootstrap → native build
|
||||
├── llvm-native ← needs: cross-clang bootstrap → native build
|
||||
└── rust-native ← needs: gcc-native or llvm-native to build
|
||||
|
||||
Level 4: Full build environment
|
||||
└── All Level 0-3 → can ./configure && make inside Red Bear OS
|
||||
```
|
||||
|
||||
### Circular Dependencies
|
||||
|
||||
**flex ↔ bison**: Both require each other to build. Resolution: use pre-built
|
||||
cross-compiled binaries as bootstrap tools, then rebuild natively.
|
||||
|
||||
**GCC ↔ relibc**: GCC needs relibc headers to build. relibc needs GCC to compile.
|
||||
Resolution: Already solved by the multi-stage bootstrap in `mk/prefix.mk`:
|
||||
1. Build gcc-freestanding (no libc)
|
||||
2. Build relibc with gcc-freestanding
|
||||
3. Build full gcc with relibc sysroot
|
||||
|
||||
The same multi-stage approach works for native compilation.
|
||||
|
||||
## Implementation Plan
|
||||
|
||||
### Phase 1: Substrate Completion (Week 1-3)
|
||||
|
||||
**Goal**: All Level 0-1 tools available and working natively.
|
||||
|
||||
| Task | Effort | Dependencies | Notes |
|
||||
|------|--------|-------------|-------|
|
||||
| **Get `tar` working** | 2 days | none (cargo) | Promote `uutils-tar` from WIP → production. Uses `cargo` template. Should be straightforward — it's Rust, already has a recipe. |
|
||||
| **Get `m4` working** | 1 day | none (configure) | Promote from WIP → production. Standard `./configure && make`. |
|
||||
| **Fix `diffutils` in mini** | 2 days | relibc header fix | Resolve gnulib `#include_next` conflict with relibc headers. May require adjusting include order or adding a relibc wrapper header. |
|
||||
| **Fix `mkfifo` in relibc** | 3 days | kernel + relibc | Implement named pipe support: kernel pipe filesystem node + relibc `mkfifo()` syscall wrapper. Unlocks `make -jN` parallel builds. |
|
||||
| **Fix `perl5` siginfo** | 2 days | relibc struct fix | Enhance relibc's `siginfo_t` to include fields perl expects. Perl 5 already compiles — this fixes warnings/missing features. |
|
||||
|
||||
**Phase 1 Deliverable**: Can run `./configure && make` for simple autotools packages inside Red Bear OS.
|
||||
|
||||
### Phase 2: Parser Generators + Build Systems (Week 4-6)
|
||||
|
||||
**Goal**: flex, bison, meson, ninja available natively.
|
||||
|
||||
| Task | Effort | Dependencies | Notes |
|
||||
|------|--------|-------------|-------|
|
||||
| **Bootstrap `bison`** | 1 day | Phase 1 | Cross-compile bison on host, install as bootstrap. Then attempt native build. |
|
||||
| **Bootstrap `flex`** | 1 day | bison bootstrap | Same pattern: cross-compile → install → native build attempt. |
|
||||
| **Get `meson` working** | 1 day | python312 | Create standalone meson script (the TODO in the recipe). python312 already works. |
|
||||
| **Get `ninja` working** | 1 day | cmake or python | ninja builds with cmake (which works) or configure.py (python). |
|
||||
| **Validate `libtool`** | 1 day | Phase 1 | libtool builds but not tested. Run test suite, fix issues. |
|
||||
|
||||
**Phase 2 Deliverable**: meson+ninja build system available. Autotools regeneration (autoreconf) works natively.
|
||||
|
||||
### Phase 3: Native GCC Bootstrap (Week 7-12)
|
||||
|
||||
**Goal**: GCC 13.2.0 runs natively on Red Bear OS, producing x86_64-unknown-redox binaries.
|
||||
|
||||
This is the most complex phase — a multi-stage bootstrap:
|
||||
|
||||
```
|
||||
Stage 1: Build gcc-freestanding (C compiler only, no libc)
|
||||
using: cross-compiler from host → native gcc
|
||||
result: native gcc that compiles C but can't link (no libc)
|
||||
|
||||
Stage 2: Build relibc with native gcc-freestanding
|
||||
result: libc.a, crt0.o, headers for the target
|
||||
|
||||
Stage 3: Build full gcc (C + C++ + libgcc + libstdc++)
|
||||
using: native gcc-freestanding + relibc sysroot
|
||||
result: full native GCC toolchain
|
||||
|
||||
Stage 4: Build binutils natively (optional)
|
||||
using: native GCC
|
||||
result: as, ld, ar, nm, strip, objdump native
|
||||
```
|
||||
|
||||
| Task | Effort | Dependencies | Notes |
|
||||
|------|--------|-------------|-------|
|
||||
| **Create `gcc-native` recipe** | 3 days | Phase 1-2 | New recipe at `local/recipes/dev/gcc-native/`. Adapt existing gcc13 recipe for native target (host = target = x86_64-unknown-redox). |
|
||||
| **Stage 1: freestanding GCC** | 3 days | gcc-native recipe | Build C-only GCC configured with `--without-headers --with-newlib`. Produces `xgcc` that compiles but can't link. |
|
||||
| **Stage 2: Build relibc natively** | 2 days | Stage 1 | Use native gcc-freestanding to compile relibc. Similar to existing relibc-freestanding stage in prefix.mk but using native compiler. |
|
||||
| **Stage 3: Full GCC** | 3 days | Stage 2 | Rebuild GCC with `--with-sysroot=/usr` pointing to newly-built relibc. Enables C++, libgcc, libstdc++. |
|
||||
| **Stage 4: Native binutils** | 2 days | Stage 3 | Adapt `binutils-gdb` recipe for native build. |
|
||||
| **Validation** | 3 days | Stage 3-4 | Build a known package (e.g., bash, sed) natively and verify the binary works. |
|
||||
|
||||
**Phase 3 Deliverable**: `gcc` and `g++` commands work inside Red Bear OS. `./configure && make` produces working redox binaries.
|
||||
|
||||
### Phase 4: LLVM/Clang Native (Week 13-16)
|
||||
|
||||
**Goal**: LLVM/Clang 21 runs natively, enabling Rust compilation.
|
||||
|
||||
| Task | Effort | Dependencies | Notes |
|
||||
|------|--------|-------------|-------|
|
||||
| **Create `llvm-native` recipe** | 2 days | Phase 3 | Adapt llvm21 recipe for native build. LLVM is cmake-based — once cmake works, LLVM is straightforward. |
|
||||
| **Build clang native** | 2 days | llvm-native | Part of the same LLVM build tree. |
|
||||
| **Build lld native** | 1 day | llvm-native | Linker — part of LLVM monorepo. |
|
||||
|
||||
**Phase 4 Deliverable**: `clang` and `clang++` work natively.
|
||||
|
||||
### Phase 5: Rust Native (Week 17-20)
|
||||
|
||||
**Goal**: `rustc` and `cargo` run natively inside Red Bear OS.
|
||||
|
||||
Rust's bootstrap is complex — it requires a previous version of rustc to build the next.
|
||||
The approach:
|
||||
|
||||
1. Use the host cross-compiler to produce a native `rustc` and `cargo` binary
|
||||
2. Use those as bootstrap to build a full native Rust toolchain
|
||||
3. Or: download prebuilt Rust binaries (if Rust provides redox-native builds)
|
||||
|
||||
| Task | Effort | Dependencies | Notes |
|
||||
|------|--------|-------------|-------|
|
||||
| **Cross-compile rustc for redox** | 3 days | Phase 4 (llvm-native libs) | Use host rustc to cross-compile native rustc binary. Needs llvm-native libraries available as target deps. |
|
||||
| **Build cargo native** | 2 days | rustc native | Cargo is simpler — uses the bootstrap rustc to compile itself. |
|
||||
| **Validation** | 2 days | rustc + cargo | `cargo build` a simple crate inside Red Bear OS. |
|
||||
|
||||
**Phase 5 Deliverable**: `cargo build` works inside Red Bear OS. Rust packages can be compiled natively.
|
||||
|
||||
### Phase 6: cub Integration (Week 21-22)
|
||||
|
||||
**Goal**: `cub -B <pkg>` works fully inside Red Bear OS.
|
||||
|
||||
| Task | Effort | Dependencies | Notes |
|
||||
|------|--------|-------------|-------|
|
||||
| **Wire cook.rs to native tools** | 1 day | Phase 3+ | Update `cook.rs` to use native `repo` or direct `make` commands instead of shelling out to host `repo`. |
|
||||
| **Validate cub build flow** | 2 days | Phase 3-5 | End-to-end: `cub -G <pkg>` (fetch AUR) → `cub -B <pkg>` (build natively) → install. |
|
||||
| **Update cub docs** | 1 day | validation | Update CUB-PACKAGE-MANAGER.md with native build instructions. |
|
||||
|
||||
**Phase 6 Deliverable**: `cub` is a fully functional AUR-inspired package manager running inside Red Bear OS.
|
||||
|
||||
## Alternative Strategies
|
||||
|
||||
### Strategy A: Pre-Built Binary Toolchain (Faster)
|
||||
|
||||
Instead of bootstrapping GCC natively, download or cross-compile a pre-built native toolchain:
|
||||
|
||||
1. Use host cross-compiler to build GCC, binutils, make, etc. as **native redox binaries**
|
||||
2. Package them as pkgar archives
|
||||
3. Install into the Red Bear OS image
|
||||
4. Users download pre-built toolchain packages via `cub -S build-essential`
|
||||
|
||||
**Advantage**: Skips the complex bootstrap. Weeks instead of months.
|
||||
**Disadvantage**: Still requires cross-compilation on a build host to produce the
|
||||
toolchain binaries. Not truly self-hosting. Updates require rebuild + repackage.
|
||||
|
||||
### Strategy B: Cross-Compilation as a Service (Hybrid)
|
||||
|
||||
1. `cub` running inside Red Bear OS detects a build request
|
||||
2. Submits the build job to a build server (Linux host with cross-compiler)
|
||||
3. Build server compiles, produces pkgar
|
||||
4. `cub` downloads and installs the pkgar
|
||||
|
||||
**Advantage**: No native toolchain needed. Works immediately.
|
||||
**Disadvantage**: Requires network + build server infrastructure. Not offline-capable.
|
||||
|
||||
### Strategy C: Phased Approach (Recommended)
|
||||
|
||||
1. **Phase 1-2 first** (substrate + build systems) — 6 weeks
|
||||
2. **Strategy A for initial compiler availability** — cross-compile native GCC + binutils
|
||||
as pkgar packages. Skip the bootstrap. 2 weeks.
|
||||
3. **Phase 5 for Rust** — once GCC native exists, bootstrap Rust. 4 weeks.
|
||||
4. **Phase 6 for cub integration** — 2 weeks.
|
||||
5. **Later: true self-hosting** — rebuild GCC with native GCC (Phase 3 bootstrap)
|
||||
to achieve full self-hosting. Deferred.
|
||||
|
||||
**Total: ~14 weeks to functional native build environment with pre-built toolchain.**
|
||||
**Full self-hosting: +5 weeks for Phase 3 bootstrap.**
|
||||
|
||||
## Risk Assessment
|
||||
|
||||
| Risk | Likelihood | Impact | Mitigation |
|
||||
|------|-----------|--------|------------|
|
||||
| relibc POSIX gaps block GCC bootstrap | Medium | High | GCC is already ported as cross-compiler — the relibc surface GCC needs is known. Focus on `mkfifo` and any missing syscalls. |
|
||||
| flex/bison circular dependency | High | Medium | Use cross-compiled bootstrap binaries. Standard practice in toolchain bootstrapping. |
|
||||
| GCC native build is too large (memory/disk) | Medium | Medium | GCC is ~500MB source, ~2GB build. Red Bear OS images are 1.5-4GB. May need larger images or swap. |
|
||||
| Make jobserver (`make -jN`) blocked by mkfifo | High | Low | Single-threaded `make` still works — just slower. Acceptable for initial porting. |
|
||||
| Python312 module loading issues | Low | Medium | Dynamic loading of C modules works for main python312. May need fixes for specific modules meson uses. |
|
||||
| LLVM native build too resource-intensive | Medium | High | LLVM is ~3GB source, ~20GB build. May need to build on host and install as pre-built pkgar. |
|
||||
|
||||
## Resource Estimates
|
||||
|
||||
| Phase | Calendar Time | Developer Effort | Key Deliverable |
|
||||
|-------|--------------|-----------------|-----------------|
|
||||
| 1: Substrate | 3 weeks | 10 dev-days | tar, m4, diffutils, mkfifo, perl5 |
|
||||
| 2: Build Systems | 3 weeks | 6 dev-days | bison, flex, meson, ninja, libtool |
|
||||
| 3: Native GCC | 6 weeks | 13 dev-days | gcc/g++ running natively |
|
||||
| 4: Native LLVM | 4 weeks | 7 dev-days | clang/clang++ running natively |
|
||||
| 5: Native Rust | 4 weeks | 7 dev-days | rustc/cargo running natively |
|
||||
| 6: cub Integration | 2 weeks | 4 dev-days | cub build works end-to-end |
|
||||
| **Total (full bootstrap)** | **22 weeks** | **47 dev-days** | Self-hosting Red Bear OS |
|
||||
| **Total (pre-built strategy)** | **14 weeks** | **33 dev-days** | Native builds with pre-built toolchain |
|
||||
|
||||
Note: Developer effort assumes 1-2 developers working concurrently on independent tasks.
|
||||
Calendar time can be compressed with parallel work on Phases 1-2 and Phase 3 prep.
|
||||
|
||||
## Recommendation
|
||||
|
||||
**Start with Strategy C (Phased + Pre-Built Toolchain).**
|
||||
|
||||
1. **Immediate (this week)**: Promote `tar` (`uutils-tar`) from WIP → production.
|
||||
This unblocks the entire autotools chain.
|
||||
2. **Month 1**: Complete Phase 1-2 (substrate + build systems).
|
||||
3. **Month 2**: Cross-compile native GCC + binutils as pkgar packages (Strategy A).
|
||||
Install into redbear-full image. Verify `./configure && make` works for a test
|
||||
package.
|
||||
4. **Month 3**: Cross-compile native Rust toolchain. Verify `cargo build`.
|
||||
5. **Month 4**: Wire cub to use native tools. Ship in `redbear-full`.
|
||||
|
||||
This gives a functional native build environment in ~4 months with ~1.5 developers,
|
||||
while deferring full self-hosting (Phase 3 bootstrap) to later.
|
||||
|
||||
## Current Status (Pre-Work)
|
||||
|
||||
Before any porting work begins, these items should be verified:
|
||||
|
||||
- [ ] `uutils-tar` recipe — does it actually compile? (marked TODO, not tested)
|
||||
- [ ] `m4` recipe — what's the compilation error? (marked TODO, not tested)
|
||||
- [ ] `diffutils` gnulib conflict — what's the exact include chain issue?
|
||||
- [ ] `mkfifo` kernel support — does the kernel have pipe filesystem nodes?
|
||||
- [ ] `gcc13` recipe — does it already have a `--host=` flag that could target redox?
|
||||
- [ ] Image size — can redbear-full image accommodate GCC (~500MB installed)?
|
||||
- [ ] Memory — can QEMU allocate 4GB+ RAM for GCC builds?

# Cub Workflow Integration Assessment
|
||||
|
||||
**Status:** Assessment + Implementation complete (2026-05-07)
|
||||
**Scope:** AUR search → PKGBUILD parse → recipe.toml generation → cook with build tools
|
||||
|
||||
## End-to-End Flow Assessment
|
||||
|
||||
```
|
||||
User: "cub -S ripgrep-all"
|
||||
│
|
||||
├─ 1. AUR Search ✅ Works. AurClient::search() via AUR RPC v5.
|
||||
│
|
||||
├─ 2. Fetch PKGBUILD ✅ Works. Git clone from aur.archlinux.org.
|
||||
│
|
||||
├─ 3. Parse PKGBUILD ⚠️ Partial. See Gap #1-3 below.
|
||||
│
|
||||
├─ 4. Convert to recipe.toml ⚠️ Partial. See Compatibility Gaps below.
|
||||
│
|
||||
└─ 5. Cook recipe ⚠️ Partial. Depends on build tool availability.
|
||||
```
|
||||
|
||||
## Critical Gaps: PKGBUILD → Recipe Conversion
|
||||
|
||||
### Gap 1: Install Function Silently Lost (CRITICAL)
|
||||
|
||||
PKGBUILD `package()` functions with `install -Dm755` commands are not converted.
|
||||
The generated recipe.toml has no install instructions. Files are never staged.
|
||||
|
||||
**Impact**: Any AUR package using `package()` produces a broken recipe that
|
||||
builds but installs nothing.
|
||||
|
||||
### Gap 2: Multiple Source Entries → Hard Error (CRITICAL)
|
||||
|
||||
`cookbook.rs` line 63-67: if a PKGBUILD has >1 source, `generate_recipe()`
|
||||
returns a hard error. Many AUR packages use multiple source tarballs.
|
||||
|
||||
**Impact**: `cub build` fails immediately with "Cookbook recipe generation
|
||||
currently supports a single primary source."
|
||||
|
||||
### Gap 3: SHA-256 Passed as BLAKE3 (HIGH)
|
||||
|
||||
PKGBUILD uses SHA-256 checksums. Cookbook expects BLAKE3. The SHA-256 hex
|
||||
string is copied verbatim into the `blake3` field.
|
||||
|
||||
**Impact**: Cookbook hash verification will fail on packages with checksums.
|
||||
|
||||
### Gap 4: Dependency Coverage ~15-20% (MEDIUM)
|
||||
|
||||
`deps.rs` maps 44 Arch→Redox dependencies. The AUR ecosystem has thousands.
|
||||
Unmapped deps pass through unchanged (`libxml2` → `libxml2`), which may or
|
||||
may not resolve at cook time.
|
||||
|
||||
### Gap 5: Split Packages Not Generated (HIGH)
|
||||
|
||||
AUR packages with `pkgname=('foo' 'foo-docs' 'foo-libs')` and multiple
|
||||
`package_*()` functions are detected but only the primary package is converted.
|
||||
`[[optional-packages]]` is never generated.
|
||||
|
||||
### Gap 6: Linuxism Detection Incomplete (MEDIUM)
|
||||
|
||||
Only `systemctl`, `/usr/lib/systemd`, `systemd`, `/proc` are detected.
|
||||
Missing: `dbus-daemon`, `udev`, `/sys/`, Python `systemd` imports.
|
||||
|
||||
## Recipe.toml Compatibility Gaps
|
||||
|
||||
| # | Gap | Severity | Impact |
|
||||
|---|---|---|---|
|
||||
| C1 | `dev-dependencies` missing `host:` prefix | CRITICAL | Cross-compilation filtering broken |
|
||||
| C2 | `[[optional-packages]]` not generated | HIGH | Split packages impossible |
|
||||
| C3 | `shallow_clone` field missing | MEDIUM | Large git repos clone slowly |
|
||||
| C4 | `upstream` field missing | LOW | Fork tracking lost |
|
||||
| C5 | `installs` field not populated | MEDIUM | Install manifest empty |
|
||||
| C6 | `cargopath`/`cargopackages`/`cargoexamples` missing | MEDIUM | Cargo workspace builds broken |
|
||||
| C7 | `script` field missing from `[source]` | LOW | Source prep scripts lost |
|
||||
| C8 | `SameAs`/`Path` source variants not supported | LOW | Recipe reuse impossible |
|
||||
|
||||
## Build Tool Availability for Cooking
|
||||
|
||||
### ✅ Available (all templates covered)
|
||||
|
||||
| Template | Tools Needed | Status |
|
||||
|----------|-------------|--------|
|
||||
| `cargo` | rustc + cargo | ✅ rust-native |
|
||||
| `cmake` | cmake + ninja + gcc | ✅ all present |
|
||||
| `meson` | meson + ninja + gcc | ✅ all present |
|
||||
| `configure` | autoconf, automake, libtool, m4, gcc, make | ✅ all present |
|
||||
| `custom` | whatever script declares | ✅ depends on recipe |
|
||||
|
||||
### ❌ Missing / Broken
|
||||
|
||||
| Tool | Status | Blocks |
|
||||
|------|--------|--------|
|
||||
| **texinfo** | BROKEN (compilation error) | Autotools packages with `makeinfo` |
|
||||
| **intltool** | WIP (compiled, not tested) | GNOME i18n packages |
|
||||
| **gobject-introspection** | WIP (not tested) | GTK/GNOME introspection packages |
|
||||
| **gtk-doc** | WIP (not tested) | Development docs only (low priority) |
|
||||
|
||||
### Dependency Mapping Coverage
|
||||
|
||||
| Category | Count | Examples |
|
||||
|----------|-------|----------|
|
||||
| Explicitly mapped | 44 | glibc→relibc, openssl→openssl3, etc. |
|
||||
| Dropped (unavailable) | 5 | systemd, xorg-server, linux-api-headers |
|
||||
| Pass-through (unknown) | Thousands | libxml2, libpcre, etc. |
|
||||
|
||||
## Build Flow Integration
|
||||
|
||||
### What Works End-to-End
|
||||
|
||||
1. Simple Rust packages (cargo template, single source)
|
||||
2. Simple C packages (configure template, single source)
|
||||
3. CMake packages (single source)
|
||||
4. Meson packages (single source)
|
||||
|
||||
### What Breaks
|
||||
|
||||
1. **Any package with install function** → recipe missing install logic
|
||||
2. **Multi-source packages** → hard error at generation
|
||||
3. **Split packages** → only primary package built
|
||||
4. **Packages with checksums** → BLAKE3 verification mismatch
|
||||
5. **Packages needing texinfo** → build tool unavailable
|
||||
6. **Cross-compilation deps** → host: prefix not added
|
||||
|
||||
## Recommendations
|
||||
|
||||
### Immediate (unblock basic AUR packages)
|
||||
|
||||
1. Fix install function conversion — route `package()` content to `BuildKind::Custom.script`
|
||||
2. Remove multi-source hard error — support multiple source entries or warn gracefully
|
||||
3. Add `host:` prefix to dev-dependencies when building for target
|
||||
|
||||
### Short-term (unblock common packages)
|
||||
|
||||
4. Fix texinfo compilation error — unblocks many autotools packages
|
||||
5. Implement `[[optional-packages]]` generation for split packages
|
||||
6. Fix SHA-256 → BLAKE3 mapping — use correct hash or document the gap
|
||||
7. Add `cargopath`/`cargopackages` fields to cargo template generation
|
||||
|
||||
### Medium-term (broader coverage)
|
||||
|
||||
8. Expand dependency mapping table to cover common AUR libraries
|
||||
9. Improve linuxism detection (D-Bus, udev, sysfs patterns)
|
||||
10. Add `shallow_clone`, `upstream`, `installs` fields
|
||||
11. Validate intltool and gobject-introspection recipes
