Both VoiceCatMac and VoiceCatiOS failed to link with 'Undefined symbols
for architecture arm64: _rnnoise_create/_rnnoise_destroy/_rnnoise_process_frame'.
Root cause: build-xcframework.sh merged vcpkg deps into the fat static lib but
NOT the locally-built vendored librnnoise.a (a CMake target from
third_party/rnnoise/ linked privately into voicecat via VOICECAT_HAS_NS — not a
vcpkg dep). The xcframework had been rebuilt after the RNNoise commit but still
omitted the symbols, so every slice's libvoicecat-fat.a referenced _rnnoise_*
with no defining object. The iOS slices were also stale (pre-rnnoise) and
absent from the xcframework entirely.
Fix: build-xcframework.sh now also collects .a files from build/<preset>/lib/
(excluding libvoicecat*) so vendored CMake-target static libs like librnnoise.a
get merged in. Future-proof: any new vendored static-lib target landing in
build/<preset>/lib/ is picked up automatically. README 'Fat static library'
section updated.
Verify: rebuilt VoiceCatCore.xcframework --all → all 3 slices (macos-arm64,
ios-arm64, ios-arm64-simulator) now carry the 10 _rnnoise_* symbols; fat lib
~30 MB → ~33 MB. xcodebuild Debug BUILD SUCCEEDED for VoiceCatMac, VoiceCatiOS
(iphonesimulator arm64), and VoiceCatiOS (iphoneos arm64). No core/ABI/proto
changes — xcframework artifact + build script only.
Add scripts/dist-ios-adhoc.sh and scripts/asc_api.py to build an ad-hoc
signed IPA and the OTA web-install files (manifest.plist + index.html)
for sharing the iOS client with registered devices before TestFlight.
- asc_api.py: App Store Connect API helper (ES256 JWT via cryptography,
urllib) to register device UDIDs and list registered devices.
- dist-ios-adhoc.sh: registers UDIDs, builds the iOS device xcframework
slice, archives + exports with method=release-testing using
-allowProvisioningUpdates, and stages the install files into
dist/ios-adhoc/.
- Document the workflow in clients/apple/README.md; ignore __pycache__.
Lays the groundwork for the macOS (AppKit) and iOS (SwiftUI) clients with a shared
Swift core wrapping the C ABI, mirroring the proven Windows VoiceCat.Interop layer.
Architecture decision: macOS UI = AppKit (not SwiftUI) for the most mature VoiceOver
accessibility story — same rationale as the Windows client's WinForms-over-WinUI-3
decision. iOS stays SwiftUI. Recorded in docs/roadmap.md §2.
Build infrastructure (Phase 0):
- clients/apple/scripts/build-xcframework.sh: runs cmake --preset apple-dev, merges
libvoicecat.a + 107 vcpkg static deps into a single ~30 MB fat static library
(libvoicecat-fat.a) via libtool -static (SPM binary targets link one .a per slice),
stages voicecat.h + a generated module.modulemap (module VoiceCatC) into the headers,
runs xcodebuild -create-xcframework -> clients/apple/VoiceCatCore.xcframework.
VoiceCatCore Swift Package (Phase 1):
- Package.swift: binary target (VoiceCatCoreXCF) + library (VoiceCatCore) + test target.
- Sources/VoiceCatCore/: 7 files mirroring the C# VoiceCat.Interop patterns adapted to
Swift native C interop — Enums (9 Swift mirrors of C enums, UInt32-backed), Config,
Event (copies ev.text to String inside the callback — the #1 lifetime rule), Models
(10 Swift value types), Marshaling (C arrays -> Swift + immediate vc_free_*),
Callbacks (@convention(c) + Unmanaged.passUnretained, the Swift analog of C#'s
[UnmanagedCallersOnly] + GCHandle), VoiceCatClient (owns vc_client* as OpaquePointer,
all 38 C ABI functions, deinit -> vc_client_destroy then frees config CStrings, event
delivery on main queue via coalesced DispatchQueue.main drain).
Tests — 6/6 green (swift test against a real voicecat-server):
- testConnectTofuAuthListChannelsRoundTrips, testAdminChannelCrudAccountCrudRoundTrips,
testScreenAudioStreamStartsAndStops, testPerStreamRecvControlsRoundTrip, plus two
static smoke tests. Catches Swift-specific interop bugs (@convention(c) callback
lifetime, Unmanaged pointer resolution, CString memory management, enum raw-value
bridging, struct layout) that C++ ctest cannot. C++ suite still 21/21 green.
Docs updated (house rule): tech-stack.md §2, architecture.md §4, roadmap.md M4 + §2,
clients/apple/README.md (full rewrite), PROGRESS.md, .gitignore.
macOS port groundwork — core, server, tools, and tests now build and run on
macOS 26.5 / Apple Silicon. ctest --preset dev green 21/21 (2 consecutive runs).
apple-dev produces valid arm64 libvoicecat.a + XCFramework for the Swift Package.
Three real cross-platform bugs found and fixed (all latent on Windows/Linux):
1. test_m2_voice.cpp POSIX branch missing <netdb.h> — Linux glibc transitively
includes it, macOS doesn't. Would fail on any strict POSIX system.
2. SIGPIPE killing processes on macOS — writing to a closed TCP socket raises
SIGPIPE by default (doesn't exist on Windows, benign on Linux). Fixed by
ignoring SIGPIPE in both core client init and server startup (POSIX-only,
#ifndef _WIN32). Production fix, not just tests.
3. Use-after-free of Asio's kqueue reactor on server shutdown — the
deterministic test_tofu_flow segfault. TcpServerConn's tls_read_loop runs on
a blocking-I/O thread; when Server::run() returned, io_context was destroyed
while those threads were still running. On macOS kqueue the reactor pointer
is null'd immediately -> segfault in socket.close(). Latent on Windows IOCP
and Linux epoll. Fix: TcpAcceptor now tracks connections; new shutdown()
closes all + joins threads before io is destroyed; Server::stop() now closes
acceptor + media_relay too (was just io.stop()).
Verified: dev + apple-dev presets build green, 21/21 tests pass, server starts
+ two vccli text chat over TLS (M1 on Mac), vccli --voice starts MIC stream via
CoreAudio (M2 protocol-level), vccli --list-devices enumerates CoreAudio
devices, xcodebuild -create-xcframework produces valid VoiceCatCore.xcframework.
No ABI or proto changes. Docs updated: building.md, clients/apple/README.md,
PROGRESS.md, CLAUDE.md status line.
Rationalize the preset set to match the project's actual state (past M5):
- Rename dev->skeleton (no-deps stub smoke), m1-dev->dev (default dev preset)
- Drop m2-dev (cache-identical to m1-dev)
- Add release preset (optimized + tests on, symbols kept)
- Strip server-release binaries (-s linker flag)
- Add apple-dev/apple-ios/apple-ios-sim scaffolding presets for XCFramework
Add cmake/voicecat-toolchain.cmake wrapper that auto-resolves the vcpkg
triplet from the host platform (x64-mingw-static/x64-linux/arm64-osx) so
the main presets work on Windows/Linux/macOS without per-OS variants.
Update all docs (building.md, CLAUDE.md, README.md, AGENTS.md, deployment.md,
tech-stack.md, client READMEs) and stale preset-name references in code
comments. No C++ behavior changes — the core was already portable.
Turn the design into a buildable, dependency-free M0 skeleton plus the
onboarding layer so a new agent can pick up instantly.
Build system:
- CMake + CMakePresets (dev = no deps; server-release = vcpkg) + vcpkg.json
- Skeleton builds with just a C++20 compiler; deps stay off until needed
- .gitattributes (LF), .gitignore, .clang-format
Core (libvoicecat):
- core/include/voicecat.h: full C ABI (the client/server contract), stubbed
- core/proto/voicecat.proto: control-plane wire format, matches docs/protocol.md
- src/{net,crypto,codec,protocol,session,audio,core}: subsystem stubs that
return VC_ERR_NOT_IMPLEMENTED, each pointing to its design doc
- server/ (voicecat-server) and tools/vccli/ link the core
- tests/: CTest smoke test asserting the C ABI contract (behavior, not just build)
- clients/{apple,windows}: M4 placeholders
Onboarding for agents:
- CLAUDE.md: hub — build/test commands, architecture at a glance, doc map, rules
- AGENTS.md: working method (behavior-driven; clean compile is the floor not the goal)
- PROGRESS.md: living tracker — M0 done, M1 task checklist, "where we left off"
Verified: cmake --preset dev && cmake --build --preset dev && ctest --preset dev → green.
