Bluetooth requires macOS 15+ with Swift 6.2+/Xcode 26+, or the experimental [Linux/BlueZ backend](linux.md) with Swift 6.2+ and its runtime dependencies. Experimental [Windows x64/WinRT support](windows.md) uses the same engine with a native Bluetooth transport. Android remains unsupported. ## Build with CMake ```cmake add_subdirectory(/path/to/Switch2Kit/Integrations/CMake switch2kit) target_link_libraries(your_emulator PRIVATE Switch2Kit::C) -# For a macOS application bundle: -switch2kit_embed(your_emulator) +# Call the platform helper in the directory that creates the executable. +if(APPLE) + switch2kit_embed(your_emulator) +elseif(WIN32) + switch2kit_embed_windows(your_emulator) +elseif(CMAKE_SYSTEM_NAME STREQUAL "Linux") + switch2kit_install_linux(your_emulator) +endif() ``` Use a CMake build directory owned by your project. The integration builds SwiftPM sources in that directory, respecting `CMAKE_OSX_ARCHITECTURES`. On macOS, explicitly select a deployment target of 15.0 or newer when enabling this backend. An emulator supporting older macOS versions should keep the backend optional rather than silently changing its minimum. The macOS host supplies its Bluetooth usage description and, when sandboxed, Bluetooth entitlement. Linux uses normal BlueZ/system-bus permissions and `switch2kit_install_linux` rather than macOS bundle embedding; see [Linux installation](linux.md). `switch2kit_embed` copies the binding and required Swift runtime libraries; the host's normal final signing step signs the bundle. No signing identity or application entitlements are supplied by the binding. +Windows uses a native x64 MSVC-compatible CMake build and the x64 Swift toolchain. The imported target provides both `Switch2KitC.dll` and its import library. `switch2kit_embed_windows` copies the DLL and attribution notices beside the executable; the matching Swift runtime must also be installed and available to the process. It does not copy Windows system libraries or change global `PATH`. See [Windows build and runtime instructions](windows.md). + `bash scripts/build-switch2kit-c.sh` builds and inspects a universal `build/Switch2KitC.xcframework` and compiles a fresh C++ consumer for each architecture. The C distribution has a fixed-layout C ABI. Swift consumers use the SwiftPM source package; the standalone Swift XCFramework pipeline is retired (see [Swift distribution](xcframework.md)). Do not link both implementations into one process. The C binding already includes the controller engine. ## Lifecycle and input -Create the handle on the main thread, before starting support.

Remove compiler RPATHs from Linux package copies only. Exercise relocated C/SDL consumers on both maintained Windows toolchains and strengthen Linux loader tests with extraction and missing-runtime negative controls. Add shared Linux/X11 and Windows GUI archive qualification: isolated owned profiles, no developer PATH/library overrides, loaded-module location checks, stable application window, ordinary shutdown and relaunch. These do not claim hardware or pristine first-use acceptance. Fix Dolphin's MSVC /WX size conversion using the actual bounded event-capacity constant, without suppressing warnings or weakening motion tests. Include #73's documentation-index cleanup while retaining all license texts and attribution. Local reviewed tree matches 4f2876d16ddef562be9f6bc7cbb0fbc873c98493. Linux deployment/loader inspection, all 3 real SDL consumers, 19 launch-supervisor regressions, 4 repository checks, 5 distribution-notice checks and application identity/signing checks pass.

Keep unresolved and ambiguous non-system dependencies fatal and report conflict paths. Repair the Linux install fixture for compiler-selected runtime staging. Build a real transitive native runtime, remove its original location before relocated launch, and retain missing-runtime and complete-notice checks. Add four native ELF/PE deployment regressions for the OS boundary, transitive runtime copies, source immutability, missing dependencies and compiler-directory protection. Register them in the existing portable runner and C consumer CTest suite. Validated the exact tree locally: 4 Linux build/relocation tests, 4 runtime staging tests (including red/green against the original traversal), 3 Linux build-helper tests, 4 repository tests, 5 distribution-notice tests, identity/signing configuration checks, and git diff --check. Native Windows C/SDL execution still requires the new CI run; no hardware qualification is claimed. --- Integrations/CMake/Runtime.cmake | 8 ++ Integrations/CMake/StageDesktopRuntime.cmake | 23 +++- tests/c-consumer/CMakeLists.txt | 6 + tests/desktop-runtime/run.sh | 4 + tests/desktop-runtime/test_staging.py | 138 +++++++++++++++++++ tests/linux-bluez/test_build.py | 33 ++++- 6 files changed, 208 insertions(+), 4 deletions(-) create mode 100755 tests/desktop-runtime/run.sh create mode 100644 tests/desktop-runtime/test_staging.py diff --git a/Integrations/CMake/Runtime.cmake b/Integrations/CMake/Runtime.cmake index c14a5e2..0a651d5 100644 --- a/Integrations/CMake/Runtime.cmake +++ b/Integrations/CMake/Runtime.cmake @@ -32,7 +32,14 @@ elseif(_s2k_compiler_version MATCHES "Swift version 6\\.3\\.3([ (]|$)") endif() set(SWITCH2KIT_RUNTIME_ICU_LICENSE "" CACHE FILEPATH "Explicit ICU license/third-party notices for a different Swift runtime distribution") +set(_s2k_system_paths) if(WIN32) + # OS libraries are prerequisites, not part of the Swift redistribution. + file(TO_CMAKE_PATH "$ENV{SystemRoot}" _s2k_windows_root) + if(NOT IS_DIRECTORY "${_s2k_windows_root}/System32") + message(FATAL_ERROR "SystemRoot must identify the Windows installation") + endif() + set(_s2k_system_paths "${_s2k_windows_root}/System32" "${_s2k_windows_root}") find_program(_s2k_inspector dumpbin REQUIRED) set(_s2k_platform "windows+pe") set(_s2k_inspector_kind dumpbin) @@ -46,6 +53,7 @@ set(SWITCH2KIT_RUNTIME_CONFIG "${CMAKE_CURRENT_BINARY_DIR}/Switch2KitRuntimePath CACHE INTERNAL "Build-only Swift runtime deployment inputs") file(CONFIGURE OUTPUT "${SWITCH2KIT_RUNTIME_CONFIG}" CONTENT [=[ set(S2K_RUNTIME_DIRS [==[@_s2k_runtime_paths@]==]) +set(S2K_SYSTEM_RUNTIME_DIRS [==[@_s2k_system_paths@]==]) set(S2K_SWIFT_LICENSE [==[@SWITCH2KIT_SWIFT_LICENSE@]==]) set(CMAKE_GET_RUNTIME_DEPENDENCIES_PLATFORM "@_s2k_platform@") set(CMAKE_GET_RUNTIME_DEPENDENCIES_TOOL "@_s2k_inspector_kind@") diff --git a/Integrations/CMake/StageDesktopRuntime.cmake b/Integrations/CMake/StageDesktopRuntime.cmake index e458338..7c9918a 100644 --- a/Integrations/CMake/StageDesktopRuntime.cmake +++ b/Integrations/CMake/StageDesktopRuntime.cmake @@ -9,15 +9,32 @@ include("${S2K_RUNTIME_CONFIG}") if(NOT EXISTS "${S2K_LIBRARY}") message(FATAL_ERROR "The built facade is required") endif() +# Stop at files actually resolved inside the Windows installation.

Windows host runtime closure and stabilize SDL rumble regressions Scan the actual consumer executable and CMake-declared transitive runtime DLLs in addition to the facade. Separately compiled Swift clients require runtime imports (notably SwiftOnoneSupport) that an optimized facade does not, so facade-only staging can pass in-tree via the developer PATH yet fail extracted launch with STATUS_DLL_NOT_FOUND. Supply application DLL directories to the native dependency scanner and copy declared application libraries together with the compiler-owned runtime closure. Keep unresolved/ambiguous dependencies fatal, retain the resolved Windows system boundary and all license checks, and keep compiler-directory overwrite protection. Add native ELF/PE regressions for a runtime imported only by a linked fixture, missing fixture-only runtime, and missing executable/library roots. The new regressions fail on the previous staging script and pass with this repair. Also apply the previously unpublished deterministic rumble regression: verify the exact 200 ms renewal boundary, rejection after a 500 ms host stall, normal SDL duration expiry, and no effect revival using the existing clocked production adapter. Real SDL callbacks and Swift facade remain in use; production safety cutoffs are unchanged.

Scanning a previously staged executable directly can therefore select old application-local runtime copies, conflict with compiler originals, or hide a missing compiler dependency. The second SDL executable shares the same deployment directory, so repeatability is required even in a clean CI build. Inspect isolated copies of declared executable and application DLL roots, then resolve their complete dependency closure against the selected compiler and Windows system directories. Retain fatal unresolved/ambiguous dependency checks and reject duplicate application root names. Serialize scans and deployment for targets sharing an output directory without adding files to the distributed package. Add native re-staging and Windows stale-copy regressions. Keep the facade fixture in a separate source directory so re-staging does not mutate an ELF source binary's RPATH. Validation: the tested local tree exactly matches a0252bb78ed79b41e3b37dbd525c583d127199cf. Eight Linux native dependency-graph tests pass (one new PE-specific test requires Windows). Real cross-built PE imports were inspected using CMake's Windows dependency scanner: initial staging, repeat staging, replacing stale copies, and three concurrent stages pass; removing a compiler dependency remains fatal despite a previously staged copy.

The rapid native PE re-staging regression reproduced a stale DLL surviving an otherwise successful deployment.

Strengthen the Windows stale-runtime regression to retain the original size and modification timestamp while replacing all bytes. Verify that staging restores the selected compiler's exact DLL, and that a stale staged DLL cannot rescue a missing compiler dependency. Local validation: real PE dependency inspection passes initial/repeat staging, a fixture originally beside the executable, equal-size/equal-timestamp corruption repair, missing compiler dependency rejection, and three concurrent deployment operations.

Windows 6.3.3 exposed a post-link deployment timeout: one SDL target held the shared-output lock while scanning its entire dependency graph, causing the other target to exhaust the 60-second lock wait. Perform isolated dependency inspection, input validation and license acquisition independently. Hold the output lock only while updating shared application-owned libraries and notices. Keep the existing deployment wait and all unresolved-dependency, compiler-ownership and content-validation checks. Enable normalized dependency paths with guarded CMP0207 support on newer CMake. Protect build-only license downloads with a separate per-license function-scoped lock so concurrent scans cannot hash a partially downloaded cache file. Downloads remain bounded at 60 seconds, and modified license contents remain fatal. Add executable regressions proving missing dependencies are diagnosed while another process holds the copy lock, concurrent acquisition cannot consume a partial license, and changed cached licenses still fail verification. Both held-lock and partial-license failures were reproduced against the previous implementation. Local validation: 10 Linux native staging/notice tests pass, with two additional Windows-only tests retained for native CI; nine relocation supervisor tests pass. Real PE dependency inspection passes initial/repeated staging, same-size/same-timestamp corruption repair, three concurrent deployments, and missing-runtime validation while the copy lock is held. Tree 7b199491d85ae9f0e080ffc94ec305b6d283e759 exactly matches the tested local tree. Final native Windows validation is required. Windows artifact comparison identifies swiftSynchronization.dll as the previously omitted consumer dependency; the Linux SwiftOnoneSupport observation was an analogous fixture-only import, not the missing DLL in the Windows failure. --- Integrations/CMake/RuntimeNotices.cmake | 4 + Integrations/CMake/StageDesktopRuntime.cmake | 14 +- tests/desktop-runtime/test_staging.py | 135 +++++++++++++++++++ 3 files changed, 150 insertions(+), 3 deletions(-) diff --git a/Integrations/CMake/RuntimeNotices.cmake b/Integrations/CMake/RuntimeNotices.cmake index 4bd1468..5e2d927 100644 --- a/Integrations/CMake/RuntimeNotices.cmake +++ b/Integrations/CMake/RuntimeNotices.cmake @@ -4,6 +4,10 @@ function(_s2k_license name url blob output) get_filename_component(_cache "${S2K_RUNTIME_CONFIG}" DIRECTORY) set(_path "${_cache}/runtime-notices/${name}") file(MAKE_DIRECTORY "${_cache}/runtime-notices") + # A concurrent deployment must not hash a partially downloaded cache file. + # This per-license lock is independent of the application copy lock and is + # released on function return.

The SDK supervisor only waited for wmctrl -m, racing the first real application observation. Wait for both EWMH identity and the possibly empty client list before starting the application. Keep this prerequisite bounded to five seconds including probe timeouts. Preserve every subsequent observer, window, runtime-location, normal-exit and relaunch assertion; no observer error becomes a successful GUI and no application startup timeout is increased. Add seven portable failure-oriented readiness tests to the retained launch suite, plus a native Xvfb/Openbox/Xlib regression run in Linux CI. The native test owns a separate display and uses a pipe-controlled window to reproduce the exact old identity-only readiness failure, then verifies real normal-window observation, normal close and relaunch. It is explicitly an observer fixture, not an emulator, controller or hardware qualification substitute. Validation: all 19 retained launch tests and seven new readiness tests pass. The real isolated X11 reproduction and both normal-close cycles pass locally. YAML parses, the six-file diff passes git diff --check, and published tree 888cb88650da06755f4cef8b94d8f472ddb01991 exactly matches the locally tested tree. SDK product sources, protocol, transport, packaging and Windows paths are unchanged. Final native CI and affected maintained-fork pin validation are still required. --- .github/workflows/linux-bluez.yml | 4 +- tests/emulator-launch/README.md | 6 + tests/emulator-launch/linux.py | 43 ++++-- tests/emulator-launch/run.sh | 1 + tests/emulator-launch/test_linux.py | 84 +++++++++++ tests/emulator-launch/test_linux_native.py | 155 +++++++++++++++++++++ 6 files changed, 283 insertions(+), 10 deletions(-) create mode 100644 tests/emulator-launch/test_linux.py create mode 100644 tests/emulator-launch/test_linux_native.py diff --git a/.github/workflows/linux-bluez.yml b/.github/workflows/linux-bluez.yml index 0dc6ed8..a41d132 100644 --- a/.github/workflows/linux-bluez.yml +++ b/.github/workflows/linux-bluez.yml @@ -24,7 +24,7 @@ jobs: - name: Install test dependencies run: | apt-get update - apt-get install -y --no-install-recommends cmake ninja-build make g++ python3 dbus libsystemd0 nodejs + apt-get install -y --no-install-recommends cmake ninja-build make g++ python3 dbus libsystemd0 nodejs libx11-dev xvfb openbox wmctrl x11-utils - name: Preserve the exact source under test run: | # The runner owns this bind-mounted checkout, but the Swift container @@ -43,6 +43,8 @@ jobs: swift test -Xswiftc -warnings-as-errors bash tests/linux-bluez/run.sh bash tests/run.sh + - name: Exercise the real isolated X11 observer and readiness regression + run: python3 tests/emulator-launch/test_linux_native.py - name: Release package tests run: swift test -c release -Xswiftc -warnings-as-errors - name: Relocated native facade and real C++ consumers diff --git a/tests/emulator-launch/README.md b/tests/emulator-launch/README.md index 23fc1cb..3e088ca 100644 --- a/tests/emulator-launch/README.md +++ b/tests/emulator-launch/README.md @@ -18,3 +18,9 @@ The application process cannot read `/Applications`, `/Library/Developer`, `/opt The test uses macOS's `sandbox-exec` as a CI-only dependency restriction, not as a product dependency or security boundary for hostile code.

The exact Dolphin Windows diagnostic archive showed this failure after a successful complete application build, before any GUI process was started. Keep private profiles, OS-only PATH, packaged DLL/runtime inspection, normal close and relaunch mandatory. Add structured failure-stage and startup-exit-code evidence instead of freezing diagnostic prose. Add executable native Windows supervisor regressions for both emulator profiles. A compiled console fixture validates its private environment and exits with a known nonzero code; it must never satisfy GUI qualification. Missing notices and pre-existing packaged Cemu settings remain rejected. Run this regression on both Windows toolchains alongside, not instead of, the real C/SDL and extracted consumer checks. Local validation: 19 launch policy tests, 7 Linux observer tests, 4 repository integrity tests, 5 distribution notice tests, Python compilation and changed-tree whitespace validation pass. Native Windows fixture and real maintained-fork GUI validation are required in CI.

Its subsequent advertisements were permanently suppressed until some unrelated scan restart. Remove only the retiring peripheral's duplicate-admission entry in finish. Retain stable physical identity, fresh monotonically increasing connection tokens, bounded scan storage and all shared retry/consent/explicit-stop policy. This does not restart scanning, fabricate an advertisement or initiate a connection. Add three executable adaptation regressions covering continuous-scan reconnect with stale-token rejection, failure/cancellation followed by a fresh advertisement, and explicit stop/shutdown remaining stopped. Two new tests fail on the old production adapter (three assertions), and all ten pass with this repair. Local reproduction compiled the actual Swift adapter, production advertisement parser/identity/types and existing OS-boundary test double under Swift 6.2.1 on Linux. The Windows source guard was removed only in a temporary proof package; unused native entry points abort rather than pretend to implement WinRT. No such shim is distributed or committed. This is adaptation evidence, not native radio or physical-controller qualification; the real Windows Swift/WinRT CI matrix must pass on this revision.

Each README also includes build-and-launch instructions when a download is unavailable. 2. **Connect over Bluetooth.** Open **Controllers** in Dolphin or **Options > Input settings** in Cemu, click **Find Switch 2 Controllers**, allow Bluetooth access, and hold the controller's **Sync** button. Close other apps managing the same controller first. diff --git a/docs/switch2kit/linux.md b/docs/switch2kit/linux.md index f9cd742..bcbcc82 100644 --- a/docs/switch2kit/linux.md +++ b/docs/switch2kit/linux.md @@ -29,7 +29,7 @@ Writes are bounded to one outstanding D-Bus write per physical device and the ch ## Native emulators and installation -For playing games, start with the maintained [Dolphin fork](https://github.com/jmonster/dolphin#linux) or [Cemu fork](https://github.com/jmonster/Cemu#linux).

Downloads are development builds for the distribution identified by the workflow, not universal Linux binaries. For the SDK's separate pinned source-patch examples, follow the [Dolphin/Cemu source integration guide](../../Integrations/Emulators/README.md), using Linux dependencies instead of Xcode, Homebrew or MoltenVK. Both optional patches accept Linux with SDL enabled; Dolphin also requires Qt. The build helper selects Linux arguments, builds all enabled upstream installation targets, and retains the targeted macOS bundle build on Apple hosts.
