# Build And Platform Inventory

Status: live
Last updated: 2026-06-02

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 |

## 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, plus the
  RGBA pixel-format mapping used by `RTT` texture allocation. It also validates
  image channel-count to OpenGL texture format mapping, including
  invalid channel counts rejected by `Texture2D::create(Image)`, RGBA8/RGBA32F
  readback formats, byte-count math, and PBO pixel-buffer target/usage/access
  mapping used by `RTT` and `PBO` readbacks, and framebuffer status naming
  used by `RTT` and `Texture2D` diagnostics. It also owns the 2D texture target,
  framebuffer setup, readback format, mipmap target, and update component-type
  tokens used by `Texture2D`, plus cube-map binding and allocation face targets
  used by `TextureCube`. It also owns and
  validates framebuffer blit color mask and linear/nearest filters used by
  `RTT::resize` and `RTT::copy`, plus the default linear clamp-to-edge
  render-target texture parameters, texture/renderbuffer targets, depth format,
  framebuffer targets, binding queries, attachment points, and completion
  status used by `RTT::create` and framebuffer bind/restore paths, plus RTT
  clear color/depth masks and color-write-mask query tokens. `RTT` no longer
  spells GL enum names directly. It also
  validates Shape index-type, fill/stroke primitive-mode, buffer target, static
  upload usage, and vertex attribute component/normalization mapping used by
  the legacy mesh draw path, plus the PanoPainter cube-face to OpenGL
  texture-target mapping used by `TextureCube`.
  It also owns and validates sampler wrap S/T/R, min/mag filter, and desktop
  border-color parameter mapping used by legacy `Sampler`. The PanoPainter
  shader attribute binding catalog, shader stage tokens, compile/link status
  queries, active-uniform count query, and matrix-uniform transpose token used
  by legacy `Shader` creation also live here. `Shader` no longer spells GL enum
  names directly. It also owns the PanoPainter shader uniform catalog and legacy hash
  mapping used by `Shader` active-uniform discovery and the uniform uniqueness
  check. App OpenGL initialization debug severity, debug output, GL info string,
  default depth/program-point/line-smooth state, blend factor/equation, and UI
  render-target RGBA8 format tokens are cataloged and tested here too, including
  the legacy convert command and resize path. App clear color-buffer masks,
  default framebuffer binding, scissor state, and sampler filter/wrap tokens
  also consume the backend mapping. OpenGL extension enumeration query tokens
  used before runtime capability detection are cataloged here. Legacy font
  atlas texture formats, text mesh buffer targets, attribute component and
  normalization tokens, draw primitive/index type, upload usage, and active
  texture unit selection also consume the backend mapping. Canvas undo/redo
  dirty-region texture updates and readbacks also consume the backend-owned 2D
  texture target, RGBA pixel format, and unsigned-byte component mapping.
  `NodeViewport` preview rendering also consumes backend-owned viewport query,
  clear-color query, color-buffer clear mask, and blend-state tokens.
  `NodeImageTexture` preview drawing also consumes backend-owned fallback 2D
  texture bind and blend-state tokens.
  `NodeImage` drawing and remote-image texture creation also consume
  backend-owned mipmapped sampler filters, blend-state tokens, and RGBA8/RGBA
  texture format mapping.
  `NodeColorWheel` triangle-buffer setup and draw-state handling also consume
  backend-owned array-buffer, static-upload, vertex-attribute, primitive-mode,
  and blend-state tokens.
  Simple UI text, text-input, border, scroll, and animation timeline draw
  paths also consume backend-owned blend-state tokens.
  Canvas layer cube/equirect generation, clear, restore, and snapshot paths
  also consume backend-owned cube/2D texture targets, active texture units,
  blend/clear state, and RGBA8 read/write pixel mapping.
  `NodePanelGrid` heightmap preview and lightmap baking also consume
  backend-owned texture readback formats, sampler filters, depth/blend state,
  depth clears, viewport queries, color-mask booleans, active texture units,
  and float render-target formats.
  Legacy `util.cpp` OpenGL error naming and `gl_state` save/restore also
  consume backend-owned error codes, state queries, framebuffer targets,
  texture binding targets, and active texture units.
  `NodeStrokePreview` brush preview rendering also consumes backend-owned
  depth/scissor/blend state, viewport/clear-color queries, active texture
  units, 2D texture targets, copy targets, and sampler filters/wraps.
  Legacy `Texture2D`, `TextureManager`, `Sampler`, and `RTT` public headers no
  longer expose raw OpenGL enum defaults; default texture formats, sampler
  filters/wraps, and render-target formats resolve through backend-owned
  overloads.
  The Windows entrypoint also consumes backend-owned generic OpenGL error-code
  and info-string tokens; WGL context/pixel-format constants remain in the
  platform shell for a later platform-boundary slice.
  Desktop VR drawing also consumes backend-owned scissor/depth/blend state,
  depth clear masks, active texture units, and fallback 2D texture unbind
  targets while retaining the existing VR SDK/platform bridge shape.
  Canvas mode overlay, mask, and transform paths also consume backend-owned
  blend/depth state, active texture units, 2D texture copy targets, and RGBA8
  readback format tokens.
  `NodeCanvas` panorama UI rendering also consumes backend-owned sampler
  defaults, viewport/clear-state queries, blend/depth/scissor state, color
  clear masks, active texture units, fallback 2D texture unbind targets, copy
  targets, and RGBA8 render-target formats.
  Canvas resource setup also consumes backend-owned stroke-buffer
  RGBA8/RGBA16F/RGBA32F formats, flood-fill texture upload format/type,
  brush/stencil/mix sampler filters and wraps, and image channel-count texture
  formats for cube-strip imports. Clamp-to-border sampler wrap is now part of
  the backend capability catalog and test coverage.
  Early canvas draw helpers also consume backend-owned pick readback
  format/type, stroke mixer depth/scissor/blend state, saved viewport and
  clear-state queries, active texture units, fallback 2D texture unbind
  targets, and stroke background copy targets.
  Canvas stroke commit also consumes backend-owned saved viewport/clear/blend
  state, history readback format/type, active texture units, fallback 2D
  texture unbind targets, and layer compositing copy targets.
  Canvas layer merge rendering and explicit layer-merge compositing also consume
  backend-owned depth/blend state, active texture units, fallback 2D texture
  unbind targets, and merge framebuffer copy targets.
  Canvas equirectangular import drawing and depth export rendering also consume
  backend-owned depth/blend state and active texture units.
  Canvas thumbnail generation and object-drawing helpers also consume
  backend-owned saved viewport/clear/blend state, active texture units,
  readback format/type, framebuffer copy targets, and renderbuffer/depth
  attachment parameters; `src/canvas.cpp` no longer contains raw `GL_*`
  constants.
- `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.
