# Build And Platform Inventory

Status: live
Last updated: 2026-06-01

This inventory records the known build surfaces during the CMake migration.
Keep it updated as platform paths move to shared CMake targets.

## Existing Build Entrypoints

| Platform/Target | Current Entrypoint | Notes |
| --- | --- | --- |
| Windows desktop | Root `CMakeLists.txt`, preset `windows-msvc-default`; target preset `windows-vs2026-x64` retained for VS 2026 | Raw `.sln/.vcxproj` files removed on 2026-05-31; local machine currently uses Visual Studio 17 2022 |
| Windows AppX | `PanoPainterPackage/Package.appxmanifest`, `.wapproj` referenced by solution | Distribution packaging |
| macOS | `PanoPainter-OSX/` project files and `Info.plist` | Uses `NSOpenGLView` today |
| iOS | `PanoPainter/Info.plist`, related Apple sources | Uses OpenGL ES today |
| Android standard | `android/android/build.gradle`, `android/android/CMakeLists.txt` | Native library target `native-lib` |
| Android Quest | `android/quest/build.gradle`, `android/quest/CMakeLists.txt` | OVR SDK imported libraries |
| Android Focus/Wave | `android/focus/build.gradle`, `android/focus/CMakeLists.txt` | Wave SDK imported libraries |
| Linux | `linux/CMakeLists.txt` | Old CMake 3.4, C++14 flag |
| WebGL/Emscripten | `webgl/CMakeLists.txt` | Old CMake 3.4, WebGL2 flags |

## Existing Version Generation

- Script: `scripts/pre-build.py`
- Output: `src/version.gen.h`
- Current behavior: derives version from git branch, latest tag, short hash,
  commit count, and configuration argument.
- Migration requirement: root CMake should call this script through a custom
  command and avoid unnecessary tracked-file churn where possible.

## Existing Dependency Sources

Hybrid policy: migrate reliable packages to vcpkg and retain SDK/patched
dependencies until each platform triplet is proven.

| Dependency | Current Source | Initial Policy |
| --- | --- | --- |
| fmt | `libs/fmt` | Move to vcpkg |
| GLM | `libs/glm` | Move to vcpkg |
| tinyxml2 | `libs/tinyxml2` | Move to vcpkg |
| stb | `libs/stb` | Move to vcpkg or interface target if package friction |
| CURL | `libs/curl-win`, `libs/curl-android-ios` | Move to vcpkg where triplets work |
| SQLite | `libs/sqlite3` | Move to vcpkg |
| GLAD | `libs/glad` | Move to vcpkg or generated backend target |
| Catch2 | none yet | Add through vcpkg |
| OpenVR | `libs/openvr` | Retain initially |
| OVR Platform/Mobile | `libs/ovr_platform`, `libs/ovr_mobile` | Retain initially |
| Wave SDK | `libs/wave_sdk` | Retain initially |
| Wacom WinTab | `libs/wacom` | Retain initially |
| AppCenter Apple | `libs/appcenter-apple` | Retain initially |
| openh264/mp4v2/libyuv | `libs/openh264`, `libs/mp4v2`, `libs/libyuv` | Retain initially |
| jpeg helpers | `libs/jpeg` | Evaluate after image tests exist |
| poly2tri/nanort/base64/hash-library | `libs/*` | Evaluate after component split |

Known local toolchain state:

- CMake: 4.0.0-rc4
- Local Visual Studio generator selected by CMake: Visual Studio 17 2022
- Bundled vcpkg: `C:\Program Files\Microsoft Visual Studio\2022\Community\VC\vcpkg`
  (`vcpkg version` reports 2025-11-19)
- Android SDK: `C:\Users\omara\AppData\Local\Android\Sdk`
- Android NDK: `C:\Users\omara\AppData\Local\Android\Sdk\ndk\29.0.14206865`
- clang-cl: `C:\Program Files\LLVM\bin\clang-cl.exe` reports 18.1.8, but the
  selected VS 2026-preview STL expects Clang 20 or newer; see DEBT-0014 before
  treating `windows-clangcl-asan` as a passing sanitizer gate.
- Android arm64 headless configure/build passes through root CMake and the
  `platform-build` automation wrapper for `pp_foundation`, `pp_assets`,
  `pp_paint`, `pp_document`, `pp_renderer_api`, `pp_renderer_gl`,
  `pp_paint_renderer`,
  `pp_ui_core`, `pano_cli`, and their current headless test binaries,
  including foundation event/logging/task queue coverage, PNG metadata and
  decode, PPI header/layout, settings document, document
  snapshot/per-layer-frame/move/duration/face-pixel coverage, paint
  brush/stroke/stroke-script coverage, renderer shader descriptor and OpenGL
  capability coverage, UI color parsing, and layout XML parse coverage.
- `pano_cli inspect-image` reports PNG IHDR metadata as JSON and is covered by
  `pano_cli_inspect_png_metadata_smoke` with a tiny IHDR fixture.
- `pano_cli inspect-project` reports validated PPI thumbnail/body byte layout,
  body summary fields, layer/frame descriptors, and dirty-face PNG payload
  metadata, and is covered by `pano_cli_inspect_project_layout_smoke` with a
  minimal PPI fixture.
- `pp_assets_image_pixels_tests` decodes PNG payloads to RGBA8 and rejects
  corrupt image payloads.
- `pp_document_ppi_import_tests` attaches decoded PPI dirty-face payloads to
  `pp_document` layer/frame storage and rejects payloads outside document
  layers.
- `pano_cli load-project` creates a `pp_document` projection with per-layer
  frame counts, durations, and decoded face-pixel payloads when present; the
  metadata-only minimal fixture remains covered by
  `pano_cli_load_project_metadata_smoke`.
- `pano_cli create-document` supports `--frames` and `--frame-duration-ms` and
  is covered by `pano_cli_create_animation_document_smoke`.
- `pano_cli simulate-stroke` exposes the pure stroke sampler for scripted
  automation and is covered by `pano_cli_simulate_stroke_smoke`.
- `pano_cli simulate-stroke-script` loads a text stroke script fixture and is
  covered by `pano_cli_simulate_stroke_script_smoke`.
- `panopainter_validate_shaders` validates the current combined GLSL shader
  files for one vertex stage marker, one fragment stage marker, valid marker
  order, and existing relative includes.
- `pp_renderer_api` owns the canonical PanoPainter shader catalog consumed by
  the legacy OpenGL app initialization path; `pp_renderer_api_tests` validates
  catalog size, key entries, duplicate rejection, and bad path rejection.
- `pp_renderer_gl` owns headless OpenGL runtime capability detection consumed
  by the legacy app initialization path; `pp_renderer_gl_capabilities_tests`
  validates framebuffer fetch, map-buffer alignment, desktop GL float support,
  GLES float/half-float extensions, WebGL exclusion behavior, and the
  upload-type mapping used by legacy `Texture2D` and `RTT` creation.
- `windows-msvc-vcpkg-headless` validates manifest install/configure/build/test
  for the current headless component matrix; see DEBT-0007 for remaining app
  and platform triplet migration.
- `pp_ui_core` consumes vcpkg tinyxml2 only when `PP_USE_VCPKG_TINYXML2=ON`
  through the vcpkg preset; default and Android validation still use the
  retained vendored fallback tracked by DEBT-0012.

Known warnings after the current CMake app build:

- Legacy code/vendor warnings under `/W4`.
- Visual Studio vcpkg manifest warning because manifest mode is not enabled.
- `LNK4099` missing `yuv.pdb` for retained libyuv binaries.
- `LNK4098` runtime library conflict from retained vendor binaries.

Platform-specific commands should be added here when verified locally.
