Summary

Adds find_package(RunAnywhere) C++ desktop kit packaging for RCLI: static commons, public rac/ headers, generated proto headers, SCHEMA_LOCK. This is not an rcli binary.

  • cpp-desktop-kit.yml builds macos-arm64 + windows-x64. Attach-only: uploads onto an existing GitHub Release (gh release view then gh release upload).
  • release.yml builds the same kits as first-class assets. Windows is a hard assert_pair. Official CLI bottles ship from RCLI, not this repo.
  • Kit-only / prerelease GitHub Releases do not fail the Swift dist-repo gate (v0.20.26 is a stopgap kit prerelease on an existing tag).

RCLI 0.5.0 is merged: RunanywhereAI/RCLI#35

Status

Ready to merge once main is healthy (Swift dist / remaining main-line blockers) and required reviews land. Do not retarget v0.20.26. Next full SDK train is 0.20.27+.

Test plan

  • macOS kit + rcli-cxx pull/run e2e
  • Windows x64 kit + rcli.exe e2e (modelless; generate skipped without RCLI_E2E_MODEL)
  • GHA kit workflow produces windows-x64 tarball
  • Kits attached to v0.20.26 prerelease; RCLI pinned and released as 0.5.0

📝 Walkthrough

Walkthrough

The change adds C++ desktop kit configuration, packaging, consumer targets, local scripts, documentation, and CI delivery for macOS ARM64 and Windows x64. It disables in-tree RCLI builds and updates release validation.

Changes

C++ Desktop Kit

Layer / File(s) Summary
Kit build configuration
CMakeLists.txt, CMakePresets.json, cmake/CppDesktopKit.cmake, tests/kit/test_cpp_desktop_kit.c, engines/llamacpp/CMakeLists.txt
CMake configures desktop kit metadata, platform outputs, packaging targets, and a public-header smoke test. Presets select macOS ARM64 and Windows x64 packaging. Windows MSVC ARM configurations are rejected. In-tree RCLI configuration now fails with external-build instructions.
Kit staging and consumer package
cmake/PackageCppDesktop.cmake, cmake/RunAnywhereConfig.cmake.in
The packager validates schema assets, copies headers and libraries, generates metadata, and creates imported RunAnywhere targets with platform and backend linkage.
Consumption and engine-pack workflow
docs/reference/cpp-desktop-kit.md, docs/reference/generated-code-contract.md, rcli/README.md, scripts/build/fetch-private-engine-pack.sh, scripts/build/package-cpp-desktop.sh
Documentation defines kit consumption and schema locking. The in-tree RCLI is marked retired. Scripts package the kit and dispatch authenticated NeuRT or QHexRT downloads.
CI build and release delivery
.github/workflows/cpp-desktop-kit.yml, .github/workflows/pr-build.yml, .github/workflows/release.yml
CI builds platform kits, validates archives and runtime contents, creates SHA-256 checksums, uploads artifacts, and attaches manual-release assets. Release gates now use C++ desktop kit jobs instead of in-tree RCLI jobs.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 1fa67

The release upload command can execute injected shell syntax through an unsafely interpolated tag while holding write permissions, and Windows kits omit static libraries required by consumers; workflow validation also still fails on literal disabled conditions. Merge should be blocked until these release-security, Windows packaging, and validation issues are fixed.

215-227: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

The hand-written version file contains a branch that never runs.

Line 222 compares PACKAGE_FIND_VERSION_MAJOR with the full version string through EQUAL. EQUAL requires both operands to be valid numbers, and ${RAC_VERSION} is a dotted version such as 0.20.25, so the comparison is always false. Only the exact-match branch at line 219 is reachable. That matches the documented find_package(RunAnywhere @RAC_VERSION@ EXACT REQUIRED) usage, so the dead branch is misleading. Generate the file with write_basic_package_version_file(... COMPATIBILITY ExactVersion) from cmake/CppDesktopKit.cmake instead, or drop the elseif block.

Set GGML_METAL to ON explicitly in the macOS kit preset.

Use add_dependencies for target-level ordering.

DEPENDS does not create target-level dependencies for the targets in _kit_depends or for package-cpp-desktop. Add explicit dependencies to both custom targets to prevent incomplete staging or archiving.

Inline comments:
In @.github/workflows/cpp-desktop-kit.yml:
- Around line 33-34: Set the workflow-level contents permission to read, then
add contents: write specifically to the attach-release job so build jobs retain
only read access.
- Around line 25-31: Update the pull_request paths for the C++ desktop kit
workflow to include core/**, engines/**, and idl/**, matching the existing push
trigger while preserving all current path entries.

In `@cmake/PackageCppDesktop.cmake`:
- Around line 132-153: Update the library-filter logic in the RAC_BINARY_DIR
staging loop to run the file --brief probe only on Apple platforms, where dSYM
companions must be excluded; copy matching artifacts directly on other
platforms, including Windows DLLs. Preserve the existing shared-library
validation for Apple and ensure onnxruntime and sherpa-onnx DLLs reach
RAC_KIT_OUT/third_party.
- Around line 64-71: Guard RUNANYWHERE_KIT_IDL_PROTO_COUNT before the
schema_lock.h file(WRITE) call: validate that the lock value exists and fail
clearly, or assign a numeric default when absent, ensuring
RUNANYWHERE_IDL_PROTO_COUNT is always emitted with a valid replacement token.
Keep the existing schema hash and version validation unchanged.
- Around line 198-204: Update the Windows branch configuring
RUNANYWHERE_KIT_SYSTEM_LIBS so the packaged target exports its CURL::libcurl and
ZLIB::ZLIB dependencies, and ensure Windows dependency discovery or archive
staging supplies those libraries for consumers when RAC_DESKTOP_ADAPTER is
enabled. Keep the existing Windows system libraries intact and use the
established dependency variables or _extra_link mechanism.

In `@cmake/RunAnywhereConfig.cmake.in`:
- Around line 106-118: Update the optional backend archive path construction in
the foreach loop for mlx, neurt, and qhexrt to use CMAKE_STATIC_LIBRARY_PREFIX
instead of a hard-coded lib prefix, consistently in both the EXISTS check and
IMPORTED_LOCATION for RunAnywhere::<opt> targets.
- Around line 57-92: Update the packaging flow around _runanywhere_kit_extra and
the archive handling in RunAnywhere::commons so rac_backend_* archives are
excluded from the plain RUNANYWHERE_KIT_EXTRA_LIBS entries, preventing lazy
duplicates. Preserve each backend’s whole-archive marker pairing by
deduplicating archive paths while collecting them, but do not apply
list(REMOVE_DUPLICATES) to linker flags or the surrounding whole-archive
sequences.

In `@docs/reference/cpp-desktop-kit.md`:
- Line 8: Update the fenced code block in the documentation to specify the text
language tag, using ```text instead of an untagged fence so markdownlint MD040
passes.

In `@scripts/build/fetch-private-engine-pack.sh`:
- Around line 13-17: Export the selected credential from the wrapper before
either delegation path so download-neurt.sh can read it from the environment;
update the token-handling flow around TOKEN and preserve the existing
NEURUN_TOKEN/GH_TOKEN fallback and missing-token check.
- Around line 5-6: Update the argument handling in fetch-private-engine-pack.sh
so the windows-arm64 target is converted to win-arm64 before being passed as the
--abi value to download-qhexrt.sh, while preserving existing mappings and
behavior for other targets.

In `@scripts/build/package-cpp-desktop.sh`:
- Around line 5-16: Update the no-argument preset selection in the case
statement so the Linux branch uses the documented non-Darwin default
cpp-desktop-windows-x64 instead of the macOS preset, while preserving the
existing Darwin and other-host behavior.

@coderabbitai review

Please review this PR in detail. Focus on:

  • the C++ desktop kit packaging contract (find_package(RunAnywhere), proto headers, SCHEMA_LOCK)
  • Windows-on-ARM host targeting AMD64 / MSVC llama.cpp
  • MSVC whole-archive linking ($<LINK_LIBRARY:WHOLE_ARCHIVE>)
  • CI checks that the tarball actually contains generated proto headers

@sanchitmonga22 I found two issues.

  1. High — The Windows kit is not self-contained for a clean find_package(RunAnywhere) consumer.
    core/CMakeLists.txt exports archive_static, zlibstatic, bz2_bundled, and CURL::libcurl as Windows link dependencies. cmake/PackageCppDesktop.cmake does not stage zlibstatic, bz2_bundled, or the vcpkg static curl archive. cmake/RunAnywhereConfig.cmake.in also skips find_dependency(ZLIB) and find_dependency(CURL) on Windows. It only exports Windows system libraries.

    A downstream RCLI link will therefore fail on unresolved libarchive, zlib, bzip2, and curl symbols, or on missing zlibstatic.lib and bz2_bundled.lib.

    Update the package contract to do one of these:

    • stage all required Windows static archives and add their full kit-relative paths to RunAnywhere::commons; or
    • require the matching vcpkg dependencies with find_dependency and document that requirement.

    The first option better matches a desktop kit that contains static commons and its transitive dependencies.

    Relevant locations: cmake/PackageCppDesktop.cmake, Lines 157-189; cmake/PackageCppDesktop.cmake, Lines 199-201; cmake/RunAnywhereConfig.cmake.in, Lines 38-42; and core/CMakeLists.txt, Lines 1294-1314 and 1335-1345.

  2. Medium — The proto-header tarball check does not run for all relevant PR changes or for release assets.
    .github/workflows/cpp-desktop-kit.yml correctly checks for include/runanywhere/proto/model_types.pb.h and share/runanywhere/SCHEMA_LOCK. However, its pull_request.paths list excludes core/**, engines/**, and idl/**. A PR that changes generated proto headers, the IDL lock, or kit inputs can skip this workflow.

    The release jobs in .github/workflows/release.yml also create and upload the tarballs without the corresponding tarball-content check. A release can therefore publish a malformed kit even though the standalone workflow has the assertion.

    Add the same relevant source paths to the pull-request filter. Add a shared tarball validation step to both release kit jobs. Prefer validating all expected *.pb.h entries, plus SCHEMA_LOCK, rather than one representative header.

    Relevant locations: .github/workflows/cpp-desktop-kit.yml, Lines 24-30 and 49-65; .github/workflows/release.yml, Lines 781-792 and 823-836.

The reviewed MSVC changes are correct:

  • $<LINK_LIBRARY:WHOLE_ARCHIVE,...> is the correct replacement for a raw /WHOLEARCHIVE: item in INTERFACE_LINK_LIBRARIES. The project requires CMake 3.24, so this feature is available.
  • The llama.cpp Windows guard checks that MSVC targets x64 before it changes CMAKE_SYSTEM_PROCESSOR from the ARM host value to AMD64. It fails clearly for a real ARM MSVC target.

@sanchitmonga22 I reviewed the latest head. Two issues remain.

  1. High — The Windows kit still omits required bundled archives.
    rac_commons exports zlibstatic and bz2_bundled as public Windows dependencies. See core/CMakeLists.txt, Lines 1299-1303. The core configuration gives these archives the required names zlibstatic.lib and bz2_bundled.lib. See core/CMakeLists.txt, Lines 541-570.

    cmake/PackageCppDesktop.cmake copies archive_static, protobuf, Abseil, and selected vcpkg archives. Its static archive allowlist at Lines 197-201 excludes both zlibstatic.lib and bz2_bundled.lib. The Windows block at Lines 211-225 copies libcurl.lib and zlib.lib, but zlib.lib does not satisfy the zlibstatic.lib reference.

    A clean Windows consumer can therefore fail to link RunAnywhere::commons with missing zlibstatic.lib or bz2_bundled.lib.

    Copy both bundled archives into lib/ and add their kit-relative paths to RUNANYWHERE_KIT_EXTRA_LIBS. Alternatively, replace the exported bare target names with package-owned imported targets. The first option is consistent with the kit’s self-contained static-library contract.

  2. Medium — Tarball validation remains incomplete.
    The PR workflow now correctly triggers for core/**, engines/**, and idl/** changes. This fixes the previous path-filter issue.

    However, .github/workflows/cpp-desktop-kit.yml checks only model_types.pb.h and SCHEMA_LOCK. See Lines 64-70 and Lines 110-116. core/CMakeLists.txt defines a larger generated protobuf set and requires a .pb.h for every listed .pb.cc. See Lines 1431-1488 and Lines 1538-1548.

    The release jobs also package and upload both kit tarballs without any tarball-content check. See .github/workflows/release.yml, Lines 772-837. A release can publish a tarball with missing generated headers or SCHEMA_LOCK.

    Derive the expected header list from the generated protobuf source list, or maintain one canonical manifest. Validate every required .pb.h and share/runanywhere/SCHEMA_LOCK in both standalone workflow jobs and both release jobs before checksum generation.

The MSVC-focused changes are correct:

  • CMake 3.24 supports $<LINK_LIBRARY:WHOLE_ARCHIVE,...>. The expression is appropriate for the imported static plugin archives.
  • The llama.cpp guard only changes CMAKE_SYSTEM_PROCESSOR when MSVC targets x64. It rejects an actual ARM MSVC target.

@coderabbitai review

Follow-up to the in-tree CLI removal:

  • rcli/ is gone. Public SDKs no longer build or bottle the CLI. Official CLI is RunanywhereAI/RCLI and consumes a released find_package(RunAnywhere) kit only.
  • Integration / unit tests for the CLI live in RCLI (tests/, scripts/e2e.sh, scripts/smoke.sh).
  • The OpenAI-compatible HTTP library (rac_server) stays in this repo so any kit consumer can embed it. RCLI only wraps rcli serve.
  • Windows kit now stages zlibstatic.lib and bz2_bundled.lib (the archives rac_commons PUBLIC-links). Tarball CI checks every generated *.pb.h plus SCHEMA_LOCK, and those two libs on Windows.
  • native_rcli_* / rcli-* jobs and ./run rcli build are removed from this repo.

@sanchitmonga22 I reviewed the latest head.

The Windows archive staging and tarball validation fixes are correct. Both standalone and release kit jobs run the shared verifier before checksum generation. The verifier checks every generated .pb.h, SCHEMA_LOCK, and the required Windows archives.

I found two remaining issues.

  1. Medium — core/tests/Dockerfile.linux-tests still enables the removed in-tree CLI.
    The Dockerfile configures CMake with -DRAC_BUILD_CLI=ON. The root CMakeLists.txt now fails configuration when this option is enabled. Any use of this Dockerfile will fail before it builds the test image.

    Remove the retired CLI option and its CLI-specific comments. If this Dockerfile is obsolete with the in-tree CLI tests, remove it and its references instead.

  2. Low — Generated-code documentation names a deleted release job.
    docs/reference/generated-code-contract.md states that release.native_rcli_macos runs generate-idl. That job no longer exists. scripts/AGENTS.md also documents RA_SKIP_BUILD as reusing an in-tree rcli build, although the telemetry script now exits as retired.

    Update these documents to describe the current kit workflow, or remove the obsolete CLI-specific entries.

Learning: The in-tree `rcli/` product is retired. The official CLI is maintained in `RunanywhereAI/RCLI`, which consumes a released C++ desktop kit through `find_package(RunAnywhere)`. CLI unit, integration, smoke, and E2E tests belong in the RCLI repository.

Learning: In `runanywhere-sdks`, `rac_server` remains an embeddable OpenAI-compatible HTTP library for C++ desktop kit consumers. RCLI only wraps its `rcli serve` command.

Addressed the still-valid leftovers on 717462b4f:

  • cpp-desktop-kit.yml now puts inputs.attach_tag in ATTACH_TAG and runs gh release upload "$ATTACH_TAG".
  • core/tests/Dockerfile.linux-tests no longer passes -DRAC_BUILD_CLI=ON (that option is a configure hard error). RAC_BUILD_SERVER stays.
  • package-cpp-desktop.sh usage now states Darwin/Windows defaults and that Linux needs an explicit preset.
  • scripts/AGENTS.md no longer describes RA_SKIP_BUILD as an in-tree rcli rebuild.
  • docs/reference/generated-code-contract.md no longer names release.native_rcli_macos (db598c093).

Windows zlibstatic.lib / bz2_bundled.lib staging was already in PackageCppDesktop.cmake (copy by filename + FATAL_ERROR if missing). Those archives are not CMake targets, so they are not on the CppDesktopKit.cmake $<TARGET_FILE:...> list. The retired if: false native_rcli_* jobs are gone from release.yml.

sanchitmonga22 added a commit that referenced this pull request Aug 24, 2026
Cut as 0.20.27 rather than 0.20.26: a separate stopgap "C++ desktop kits"
release (draft, tag v0.20.26, PR #776) already claims that tag and explicitly
asks that it not be retargeted, naming 0.20.27+ as the next real SDK train.
Discovered mid-flight by an independent audit pass; the in-progress v0.20.26
release build was cancelled before it collided with that draft, and the
v0.20.26 tag was left untouched from that point on.

Ships the full engine-artifact pipeline from tonight's work: NeuRT and QHexRT
as pinned prebuilt archives from the private neurun repo, the QAIRT/QNN runtime
the Hexagon engine depends on at execution time as its own private pinned
artifact (briefly public for a few hours, moved back to private), and
check_qairt_pairing.sh guarding the two pins against drift.

Also folds in an independent adversarial audit's confirmed findings: stale
"public QAIRT" comments left behind by the public->private move (in three
files), a real bug in the QAIRT release-content gate section (its .sha256
sidecar comparisons failed on byte-identical hashes because
publish-qairt-runtime.sh wrote shasum's default "hash  filename" format while
every other sidecar in this pipeline is bare-hash -- fixed the publisher,
hardened the gate's parser to extract the first field regardless, and
re-uploaded corrected sidecars), the hand-staged-path guard extended to cover
QAIRT/RA_QNN_RUNTIME_DIR, and a "latest" release-marker mixup on the private
neurun repo (publishing the QAIRT runtime there marked IT latest instead of the
real engine release -- fixed and documented as a standing trap in that repo's
release skill).

Changelog prose is hand-written per Flutter package, as always.

Ship RunAnywhere-cpp-desktop-{macos-arm64,windows-x64} tarballs from a
dedicated workflow and from release.yml. In-tree rcli bottles are no
longer a release gate; the product CLI lives in RunanywhereAI/RCLI and
consumes the kit (proto headers + SCHEMA_LOCK, never a second protoc).

macos-14 does not ship Xcode 26.6, which setup-toolchain requires.
Install ninja from Homebrew and use the image compiler instead.

CMake reports CMAKE_SYSTEM_PROCESSOR=ARM64 on Snapdragon hosts even when
vcvarsall amd64 has selected Hostx64/x64/cl.exe. ggml then takes its ARM
MSVC path and fatals ("use clang"). Pin the x64 kit preset to AMD64 and
detect the same mismatch in the llama.cpp engine so configure matches
the compiler we actually invoked.
The v0.20.25 macOS kit originally uploaded to GitHub was a 32MB archive
without include/runanywhere/proto or SCHEMA_LOCK, so RCLI CI failed on
`test -f` with no useful log. GHA already staged a complete prefix;
assert the tarball contains those files before uploading the artifact.
Putting /WHOLEARCHIVE:C:/... in INTERFACE_LINK_LIBRARIES makes Ninja
treat the flag as a path and fail FindFirstFileExA when RCLI links the
kit. Use $<LINK_LIBRARY:WHOLE_ARCHIVE,...> instead.
Tighten workflow permissions, keep in-flight Windows kit jobs, quote the
checksum path, and fail closed when Linux has no kit preset. Packaging now
guards IDL_PROTO_COUNT, Apple-only file(1) filtering, Windows libcurl/zlib
export, and whole-archive backend linking without flattening flag pairs.

The desktop CLI, its tests, installers, and bottles live in

Keep rac_server in this repo (any consumer can embed the OpenAI-compatible

- point docs and ./run rcli at the RCLI repository

workflow only attaches to an existing GitHub Release. Kit-only prerelease
tags no longer fail the Swift dist-repo gate, so PRs can merge after a
stopgap kit prerelease on an existing version tag.

Public C++ kits stay OSS (llama.cpp, Sherpa, ONNX, MLX). NeuRT (macOS
ANE, from neurun) and QHexRT (Windows ARM64 Hexagon NPU) ship as
workflow-only overlay tarballs. Configure fails closed without the
pinned prebuilt; overlays never attach to the GitHub Release.

find_package(RunAnywhere) discovers overlay archives dropped onto a
public prefix. Kit and release CI build the overlays on macos-14 and
windows-11-arm using NEURUN_TOKEN.

…oad work on Windows

Public desktop tarballs were failing verification because
core/include/rac copied rac_plugin_entry_neurt.h. Exclude private
engine headers from the OSS prefix and ship the NeuRT plugin header
in the private overlay instead.

QHexRT CI on windows-11-arm was rejecting a valid payload: Git-Bash
paths mixed with native Python junctions, so current did not read as
versions/<receipt>. Convert paths with cygpath before Python and
resolve mixed junction targets in read_target.
Git-Bash find does not recurse junctions, so the QHexRT overlay packager
saw an empty runtime even after a successful download. Resolve current
through _selection and copy DLLs with Python, and pass Windows paths into
the QAIRT downloader the same way the QHexRT fetch already does.

Bump the train so C++ desktop kits and private NeuRT/QHexRT overlays
ship as first-class release artifacts.

Desktop kit jobs never fetched Sherpa-ONNX, so capability_check returned
BACKEND_UNAVAILABLE while HAS_SHERPA looked true. Prefetch the prebuilts,
fail configure/package on a stub, and keep a rebuild_cpp_desktop publish
path so Apple/WASM from the candidate can be reused.
