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.
VoiceCat
Self-hosted, native voice & text chat in the spirit of classic TeamSpeak / Mumble —
channel-based voice, channel + private text, one server you run yourself. Plain TCP
(control) and UDP (media), no WebRTC. Encrypted by default. A shared C++ core
(libvoicecat) drives native clients (Swift on macOS/iOS, C# on Windows) and the server.
Status: Design complete in
docs/. M1–M5 are implemented — real TLS control plane, encrypted UDP voice (Opus), multi-stream, TOFU identity pinning, channel tree, permissions, moderation, disconnect/keepalive/reaper. Windows WinForms C# client shipped (M4). macOS/iOS Swift client is next. SeePROGRESS.mdanddocs/roadmap.md.

Build
The default development preset is dev — it builds everything (server + tools + tests)
with real vcpkg deps. It works on Windows, Linux, and macOS (vcpkg triplet auto-resolved).
# one-time vcpkg setup:
git clone https://github.com/microsoft/vcpkg && ./vcpkg/bootstrap-vcpkg.sh # .bat on Windows
export VCPKG_ROOT=/path/to/vcpkg # Linux/macOS; or $env:VCPKG_ROOT on PowerShell
# configure + build + test:
cmake --preset dev
cmake --build --preset dev
ctest --preset dev # 21 behavior tests
Artifacts land in build/dev/bin/ (voicecat-server, vccli, voicecat-admin).
The skeleton preset (no vcpkg deps, stubs only) is a fast smoke check that needs no
third-party libraries:
cmake --preset skeleton && cmake --build --preset skeleton && ctest --preset skeleton
See docs/building.md for the full preset matrix (including release,
server-release, windows-client, and Apple platform scaffolding).
